        <content xml:lang="en" type="html">&lt;p&gt;Welcome to the second edition of my monthly meanderings. For a bit of context, you can check out &lt;a href=&#34;https://chameth.com/monthly-meanderings-2025-12/&#34;&gt;the introduction to the first edition&lt;/a&gt;.&lt;/p&gt;
&lt;h3 id=&#34;website-updates&#34;&gt;Website updates&lt;/h3&gt;
&lt;p&gt;It’s been a pretty busy month for chameth.com. Three blog posts: &lt;a href=&#34;https://chameth.com/the-meaning-of-life/&#34;&gt;The Meaning of Life&lt;/a&gt; — an entry into the &lt;a href=&#34;https://www.jeremiahlee.com/posts/2026-01-indieweb-carnival/&#34;&gt;IndieWeb carnival&lt;/a&gt; where I mostly review a book on Stoicism —  &lt;a href=&#34;https://chameth.com/surge-protectors-marketing-vs-reality/&#34;&gt;Surge Protectors: Marketing vs Reality&lt;/a&gt; which is a dump of a research rabbit hole I fell into, and &lt;a href=&#34;https://chameth.com/tailscale-docker-gotcha/&#34;&gt;An Interesting Tailscale + Docker Gotcha&lt;/a&gt; which documents a fun problem I encountered.&lt;/p&gt;
&lt;p&gt;I’ve also made a new &lt;a href=&#34;https://chameth.com/films/&#34;&gt;films&lt;/a&gt; section, which is basically my Letterboxd data but free range instead of cooped up in a silo. I imported my 200-odd reviews, and for the last few I wrote the review on my site and then copied it over to Letterboxd. That’s what the IndieWeb folks call &lt;a href=&#34;https://indieweb.org/POSSE&#34;&gt;POSSE&lt;/a&gt;: publish on your own site, syndicate elsewhere. I like the idea that my website is the canonical source of truth for all the public things I generate. I want to expand this to some other areas in the future: music, video games, board games, etc.&lt;/p&gt;
&lt;p&gt;I made most of the film components into “shortcodes”, so I can drop them into arbitrary pages or posts, like so:&lt;/p&gt;
&lt;a class=&#34;film-list raised-box plain-link&#34; data-title=&#34;Film list&#34; href=&#34;https://chameth.com/films/lists/ranking/&#34;&gt;
  &lt;h3 class=&#34;plain-header&#34;&gt;Watched films ranked&lt;/h3&gt;
  &lt;div class=&#34;poster-stack&#34;&gt;
    &lt;img src=&#34;https://chameth.com/films/265/poster.jpg&#34; alt=&#34;Poster of Midsommar&#34;/&gt;&lt;img src=&#34;https://chameth.com/films/4/poster.jpg&#34; alt=&#34;Poster of Easy A&#34;/&gt;&lt;img src=&#34;https://chameth.com/films/97/poster.jpg&#34; alt=&#34;Poster of Hackers&#34;/&gt;&lt;img src=&#34;https://chameth.com/films/25/poster.jpg&#34; alt=&#34;Poster of The Matrix&#34;/&gt;&lt;img src=&#34;https://chameth.com/films/202/poster.jpg&#34; alt=&#34;Poster of Sinners&#34;/&gt;
  &lt;/div&gt;
  &lt;div class=&#34;description&#34;&gt;&lt;p&gt;Every film I’ve watched since I started logging, ranked.&lt;/p&gt;
&lt;p&gt;Obviously super subjective, and subject to change often and arbitrarily.&lt;/p&gt;
&lt;/div&gt;
  &lt;p class=&#34;count&#34;&gt;264 films&lt;/p&gt;
&lt;/a&gt;
&lt;p&gt;Finally, I added a new widget to the bottom of most pages: a “nod” button. It’s effectively a “like” or “kudos” button but deliberately does not track how many times it’s been pressed, has no social network connotations, and won’t flood my inbox or hit rate limits if it gets spammed. If you click the button, it simply sends a message to a private IRC channel that says “Someone nodded at $URL”. I’ll probably write a bit more about it in a blog post in the future.&lt;/p&gt;
&lt;h3 id=&#34;other-projects&#34;&gt;Other projects&lt;/h3&gt;
&lt;p&gt;I only have one small non-chameth.com update: a new project called &lt;a href=&#34;https://github.com/csmith/pigeonhole/&#34;&gt;pigeonhole&lt;/a&gt; which provides a really basic web service that lets you leave messages in a named cubby, and retrieve them at a later date. I’m using it to automate adding things to my Obsidian notes from my Apple Watch. There’s lots of reasons why that isn’t as simple as it sounds. I went through a bunch of iterations to try and make it work before just writing code to fix it.&lt;/p&gt;
&lt;p&gt;I wanted to do this because I’m trying to replace Todoist with just having tasks in &lt;a href=&#34;https://obsidian.md/&#34;&gt;Obsidian&lt;/a&gt;. I already used Obsidian for longer form notes, but I’ve now also started using it for drafting blog posts (I’m typing this in Obsidian right now!), and trying to keep more useful day-to-day notes. I’ll probably write a blog post with more details once I’ve figured everything out.&lt;/p&gt;
&lt;p&gt;Finally, I’ve been moving a bunch of projects to a private &lt;a href=&#34;https://forgejo.org/&#34;&gt;Forgejo&lt;/a&gt; instance, with the ultimate goal of having all of my projects live there. I’m going to mirror the contents out to GitHub and maybe other places, but Forgejo will be the single source of truth, and where all the workflows/dependency wrangling/etc happens. I’ve got &lt;a href=&#34;https://renovatebot.com/&#34;&gt;Renovate&lt;/a&gt; configured to do dependency bumps, and I’m very much liking the whole setup so far. I’m saying it a lot but again: I’ll blog about it in more detail when it’s a bit further along.&lt;/p&gt;
&lt;h3 id=&#34;entertainment&#34;&gt;Entertainment&lt;/h3&gt;
&lt;p&gt;I mentioned last month that I was playing Hogwarts: Legacy. I finished that off, and have been struggling to find something to scratch the same itch. I’ve tried a whole bunch of open world games, and basically none of them work for me. They have cumbersome control schemes (yay console ports), really awkward or sluggish movement, and so on. I think I’m just too fussy, but if I’m going to sink dozens of hours into a game it shouldn’t feel annoying or like a chore!&lt;/p&gt;
&lt;p&gt;I did play through &lt;a href=&#34;https://store.steampowered.com/app/2366980/Thank_Goodness_Youre_Here/&#34;&gt;Thank Goodness You’re Here&lt;/a&gt;, which is delightfully funny but sadly only took 3.6 hours to finish with 100% of the achievements. Still highly recommend picking it up, especially when it’s on sale for under ‘10 bob’.
I’ve also started playing through Control, and I’m enjoying the ambience. There’s an insanely sharp difficulty spike for the first boss, though, which nearly made me put it down.&lt;/p&gt;
&lt;p&gt;In other entertainment, I’ve been playing a load of turn-based games on &lt;a href=&#34;https://boardgamearena.com/&#34;&gt;Board Game Arena&lt;/a&gt; , and I’ve watched a bunch of films after barely watching any last month. Here’s another of those shortcodes to show them off:&lt;/p&gt;

&lt;p&gt;A fun post documenting using Tailscale in a very weird way to solve a relatable problem. Very much my cup of tea.&lt;/p&gt;
&lt;h4 id=&#34;i-charged-18000-for-a-static-html-pagehttpsidiallocomblog18000-dollars-static-web-page&#34;&gt;&lt;a href=&#34;https://idiallo.com/blog/18000-dollars-static-web-page&#34;&gt;I charged $18,000 for a static HTML page&lt;/a&gt;&lt;/h4&gt;
&lt;p&gt;This one’s actually from 2019, but it’s the first time I’ve come across it, and it’s a fun story. As a contractor, deciding what to bill for and what not to can be a bit messy. Downtime between meetings? The ten minutes in the shower you spent thinking through a bug? It’s a lot more clear cut if the client wants you to sit in an office, twiddling your thumbs, though.&lt;/p&gt;
&lt;h4 id=&#34;oxide-rfd-using-llms-at-oxidehttpsrfdsharedoxidecomputerrfd0576&#34;&gt;&lt;a href=&#34;https://rfd.shared.oxide.computer/rfd/0576&#34;&gt;Oxide RFD: Using LLMs at Oxide&lt;/a&gt;&lt;/h4&gt;
&lt;p&gt;A wonderfully well thought out piece about using LLMs in a respectful, sensible manner. I’d been thinking about writing something similar, but it wouldn’t have been anywhere near as well crafted as this. While I basically agree with it all, the part about LLM-generated text really resonates:&lt;/p&gt;
&lt;blockquote&gt;
&lt;p&gt;LLM-generated prose undermines a social contract of sorts: absent LLMs, it is presumed that of the reader and the writer, it is the writer that has undertaken the greater intellectual exertion.&lt;/p&gt;
&lt;/blockquote&gt;
&lt;h4 id=&#34;your-app-subscription-is-now-my-weekend-projecthttpsrselbachcomyour-sub-is-now-my-weekend-project&#34;&gt;&lt;a href=&#34;https://rselbach.com/your-sub-is-now-my-weekend-project&#34;&gt;Your app subscription is now my weekend project&lt;/a&gt;&lt;/h4&gt;
&lt;p&gt;Roberto points out that monthly SaaS subscriptions start looking even less appealing when you can just prompt an alternative into existence. &lt;a href=&#34;https://chameth.com/an-app-can-be-a-ready-meal/&#34;&gt;I talked a bit about using LLMs for one-person software before&lt;/a&gt;, and it becomes even more appealing when the alternative is paying monthly for a service that keeps shoe-horning in features you don’t want, making you agree to share data with 329 “trusted partners”, and/or repeatedly ratcheting up the price.&lt;/p&gt;
&lt;h4 id=&#34;ekuls-internet-spacehttpsekulme&#34;&gt;&lt;a href=&#34;https://ekul.me/&#34;&gt;Ekul’s Internet Space&lt;/a&gt;&lt;/h4&gt;
&lt;p&gt;I love the aesthetics of this personal site, and the data tracking that goes along with it. I’m also slightly aghast at the amount of Monster consumed! Makes me want to track more things and expose them on my own site.&lt;/p&gt;

        <content xml:lang="en" type="html">&lt;p&gt;For a while I’ve been idly thinking about a way to get smaller bits of content
onto my website without it being too annoying for me, or too hard to consume. Things
like interesting links, small project updates, and so on.&lt;/p&gt;
&lt;p&gt;I didn’t immediately come up with anything I was happy with, so just sat on it.
Ignoring the problem seems to work surprisingly well for things like this.
I’d been meaning to redesign the &lt;a href=&#34;https://chameth.com/about&#34;&gt;about page&lt;/a&gt; for a while, but wasn’t
sure what to do with all the interests I wanted to list. After ignoring the
problem for a while I came across the &lt;a href=&#34;https://chrisburnell.github.io/interests-directory/&#34;&gt;interests directory&lt;/a&gt;
and realised I could just bundle all those things into their own page.&lt;/p&gt;
&lt;p&gt;This seems amazingly obvious in hindsight, but I think I needed a bit
of a push to accept that a page just about my interests was… well…
interesting. Anyway, as the end of December rolled around, I got a similar
dose of inspiration: a flurry of monthly round-up posts from various blogs
I follow. If I bundle up all the small bits and bobs, it’ll make something
vaguely blog post shaped, and writing and consuming those is already a
solved problem. Again, pretty obvious in hindsight, and again I think I
just needed a nudge to shut up the little voice in my head saying “but those
people all have interesting things to say… do you, really?”&lt;/p&gt;
&lt;p&gt;So without further ado, welcome to the inaugural post in my new monthly
meanderings series. If you have any feedback on the format or contents,
please drop me a note with the contact form at the bottom!&lt;/p&gt;
&lt;h3 id=&#34;website-updates&#34;&gt;Website updates&lt;/h3&gt;
&lt;p&gt;As already mentioned, I reworked the &lt;a href=&#34;https://chameth.com/about&#34;&gt;about page&lt;/a&gt; and split out
a new &lt;a href=&#34;https://chameth.com/interests&#34;&gt;interests page&lt;/a&gt;. The old about page had a few lists
of interests show up in thought bubbles when you hovered over things,
which was a cool effect on desktop, but barely worked at all on mobile.
The new page gives me a lot more room for waffle, and I do like waffling.&lt;/p&gt;
&lt;p&gt;Only a single new blog post this month:
&lt;a href=&#34;https://chameth.com/exposing-game-servers-over-tailscale/&#34;&gt;exposing game servers over Tailscale&lt;/a&gt;.
Just a quick how-to I wrote up, having not found it documented usefully
anywhere before. I have a bunch of ideas for posts I want to write, but
none of them have really sparked joy quite yet, so I’m once again employing
the “sit on them for a bit and maybe inspiration will strike” approach.&lt;/p&gt;
&lt;h3 id=&#34;other-projects&#34;&gt;Other projects&lt;/h3&gt;
&lt;p&gt;I created a small collection of Docker related projects this month:
&lt;a href=&#34;https://github.com/csmith/containuum&#34;&gt;containuum&lt;/a&gt; is a go library that
helps with listing containers, and keeping that list up-to-date. On top
of that I built &lt;a href=&#34;https://github.com/csmith/centauri-docker-confd&#34;&gt;centauri-docker-confd&lt;/a&gt;
which generates a config for &lt;a href=&#34;https://github.com/csmith/centauri&#34;&gt;centauri&lt;/a&gt;
(my reverse proxy) based on running Docker containers. I already had a
way of doing that, but containuum is designed to be a bit more robust,
and I made it so the config can be passed over a network connection
instead of having to write it to disk and then signal the proxy to reload.&lt;/p&gt;
&lt;p&gt;The next project has a bit of backstory: after reading
&lt;a href=&#34;https://blog.jakesaunders.dev/my-server-started-mining-monero-this-morning/&#34;&gt;I got hacked, my server started mining Monero this morning&lt;/a&gt;
[warning: the article is interesting but a bit LLM-sloppy] I realised that I, too, was
running a vulnerable version of Umami. Luckily, as far as I can tell, it wasn’t
exploited. But it got me looking into automated vulnerability scanning. I don’t
put much stock into it normally, as you get so many false alerts, but this is one
case where it would have definitely helped. There didn’t seem to be any
good solution for my “middle-of-the-road” approach to containers (lots of containers,
but not needing Kubernetes), so I wrote &lt;a href=&#34;https://github.com/csmith/purser&#34;&gt;purser&lt;/a&gt;.
It takes every image used by a running container, runs them through
&lt;a href=&#34;https://github.com/aquasecurity/trivy/&#34;&gt;Trivy&lt;/a&gt;, and generates a combined report.
I’ll add some form of active notifications to it in the future.&lt;/p&gt;
&lt;h3 id=&#34;entertainment&#34;&gt;Entertainment&lt;/h3&gt;
&lt;p&gt;This month I’ve been playing a lot of Hogwarts: Legacy, after picking it up
for free on Epic Games. I grew up with the Harry Potter books coming out,
and while I’m not a super-fan, it still has a special appeal to me.
Obviously she-who-must-not-be-named is doing her best to out-evil Voldemort,
but I think you can still enjoy the universe despite that. Especially when
you don’t have to contribute any money that might go towards her.&lt;/p&gt;
&lt;p&gt;Anyway, the game is surprisingly fun. They did a really good job of making
it feel like an open world. You &lt;em&gt;want&lt;/em&gt; to walk around from place to place
to see everything, find all the various collectables, and so on. Compared
to Far Cry or Cyberpunk the world is a lot smaller but that means it’s far
more densely packed with stuff to do. I initially didn’t vibe with the
way combat works: it’s pretty heavily reliant on dodging or shielding against
incoming attacks, which reminded me a lot of Clair Obscur: Expedition 33.
Fortunately, it’s a lot more forgiving in Hogwarts: Legacy and I got used
to it after not too long.&lt;/p&gt;
&lt;p&gt;It’s been a relatively sedate month for other forms of entertainment.
I saw Fackham Hall and Wicked: For Good at the cinema. The former was
a funny romp, vaguely reminiscent of Airplane or The Naked Gun, as you’d
expect from something penned by Jimmy Carr. Wicked was… fine? I wasn’t
overly enamoured with part one, so it’s not a surprise I didn’t vibe with
the follow-up. If you smushed them into a single normal-length feature I think they
would have made a really good film, but two films both over two hours
long is a bit much for what actually happens.&lt;/p&gt;
&lt;h3 id=&#34;around-the-web&#34;&gt;Around the web&lt;/h3&gt;
&lt;h4 id=&#34;wikipedia-list-of-citogenesis-incidentshttpsenwikipediaorgwikiwikipedialist-of-citogenesis-incidents&#34;&gt;&lt;a href=&#34;https://en.wikipedia.org/wiki/Wikipedia:List_of_citogenesis_incidents&#34;&gt;Wikipedia: List of citogenesis incidents&lt;/a&gt;&lt;/h4&gt;
&lt;p&gt;A list of incidents where (often false) information on Wikipedia has ended up
becoming its own source. That led to Mark Dominus’ blog post titled
&lt;a href=&#34;https://blog.plover.com/wikipedia/ysolo.html&#34;&gt;Imaginary Albanian eggplant festivals… IN SPACE&lt;/a&gt;
where he discovers that a mountain on Ceres got named after a made-up festival
(and then got it fixed!)&lt;/p&gt;
&lt;p&gt;Not relying on Wikipedia as a source was drummed into us at school, but
it feels like this sort of thing is only going to get worse and worse now
LLMs are on the scene. I assume we’re already at the point where LLM
hallucinations are prevalent enough that they’ll find their way into
the training data for future iterations.&lt;/p&gt;
&lt;h4 id=&#34;simon-collisons-websitehttpscollycom&#34;&gt;&lt;a href=&#34;https://colly.com/&#34;&gt;Simon Collison’s website&lt;/a&gt;&lt;/h4&gt;
&lt;p&gt;I really like the design here. Both the homepage and how well every
journal entry is formatted. It makes me feel bad for the many walls of
text that adorn this site. The &lt;a href=&#34;https://colly.com/v4/&#34;&gt;archived v4 design&lt;/a&gt;
is also wonderful.&lt;/p&gt;
&lt;h4 id=&#34;my-dinner-with-skinnerhttpswwwyoutubecomwatchvpk-oq8iytva&#34;&gt;&lt;a href=&#34;https://www.youtube.com/watch?v=pk-Oq8iYtVA&#34;&gt;My Dinner with Skinner&lt;/a&gt;&lt;/h4&gt;
&lt;p&gt;A 43-minute-long feature film that is “just” the Steamed Hams gag from
The Simpsons done in the style of My Dinner with Andre. There’s a (much shorter)
&lt;a href=&#34;https://www.youtube.com/watch?v=1Ecg_5r1L1M&#34;&gt;behind-the-scenes video&lt;/a&gt; that
goes over the extreme amount of effort that was put into it, too.&lt;/p&gt;
&lt;p&gt;I’m still trying to wrap my head around this. It’s… something.&lt;/p&gt;
&lt;h4 id=&#34;delete-spotify-sure-but-dont-just-replace-it-with-another-subscriptionhttpsstephveecablogentertainmentdelete-spotify-sure-but-dont-just-replace-it-with-another-subscription&#34;&gt;&lt;a href=&#34;https://stephvee.ca/blog/entertainment/delete-spotify-sure-but-dont-just-replace-it-with-another-subscription/&#34;&gt;Delete Spotify? Sure, But Don’t Just Replace it With Another Subscription&lt;/a&gt;&lt;/h4&gt;
&lt;p&gt;A similar take to my own &lt;a href=&#34;https://chameth.com/escaping-spotify-the-hard-way/&#34;&gt;escaping Spotify the hard way&lt;/a&gt;,
but it avoids getting lost in the technical weeds like I did. (In my defence,
they’re very fun weeds to get lost in.) Stephanie is
also one of the people that does monthly wrap-ups, and I was pleasantly
surprised when &lt;a href=&#34;https://stephvee.ca/blog/rewinds/rewind-dec-2025/&#34;&gt;the latest one&lt;/a&gt;
popped up in my RSS reader and I saw my own site linked.&lt;/p&gt;

        <title>Blogging and the Imaginary Quality Bar</title>
        <link href="https://chameth.com/blogging-and-the-imaginary-quality-bar/"/>
        <updated>2025-09-18T00:00:00Z</updated>
        <id>https://chameth.com/blogging-and-the-imaginary-quality-bar/</id>
        <content xml:lang="en" type="html">&lt;p&gt;Recently I realised that I’ve developed a self-imposed quality bar for blog
posts. They need to be a certain length, and have a certain &lt;em&gt;substance&lt;/em&gt; to them.
They need to be generally useful in some way I can’t quite define, to some
imagined future audience. They need to have images to break up the page, and
opengraph data for when they’re linked to on social media. But… maybe they
don’t? Those things all make sense for longer “article” type posts, but not so
much for a personal blog.&lt;/p&gt;
&lt;p&gt;I’ve done some fiddling so that I can make posts without all that extra stuff.
We’ll see how it goes. The posts won’t be distinguished on the site (yet?), but
I have set up separate RSS feeds for just &lt;a href=&#34;https://chameth.com/short.xml&#34;&gt;short form posts&lt;/a&gt; and
&lt;a href=&#34;https://chameth.com/long.xml&#34;&gt;long form posts&lt;/a&gt; in case subscribers are radically opposed to one
or the other. Now I can start blogging like it’s 2005 again. But hopefully
with a bit less cringe.&lt;/p&gt;
&lt;p&gt;I’ve been staring at this post in my editor for about five minutes. The urge
to make it longer, more thorough, more article-like is really strong. This
entire paragraph is only here as a compromise with myself so I can actually
save and commit the post.&lt;/p&gt;

        <title>Fixing a loud PSU fan without dying</title>
        <link href="https://chameth.com/fixing-a-loud-psu-fan-without-dying/"/>
        <updated>2025-07-30T00:00:00Z</updated>
        <id>https://chameth.com/fixing-a-loud-psu-fan-without-dying/</id>
        <content xml:lang="en" type="html">&lt;p&gt;Three months after I &lt;a href=&#34;https://chameth.com/building-a-new-computer/&#34;&gt;built my new computer&lt;/a&gt;, it
started annoying me. There would occasionally be a noise that sounded like
a fan was catching on a cable, but there weren’t any loose cables to be a
problem. Over the course of a few weeks, the sound got progressively worse
to the extent that I didn’t want to use the computer without headphones on.
I measured the sound at 63 dB, which is about the sound of someone talking.
That may not sound terrible, but it’s a constant, nasty noise coming from
something that sits about 40cm from my head.&lt;/p&gt;
&lt;p&gt;After some investigating&lt;sup id=&#34;fnref:1&#34;&gt;&lt;a class=&#34;footnote-ref&#34; href=&#34;#fn:1&#34; role=&#34;doc-noteref&#34;&gt;1&lt;/a&gt;&lt;/sup&gt;, I identified the PSU fan as the culprit. I have
a Cooler Master V750 SFX, which is not super high-end, but wasn’t cheap, either.
It shouldn’t be developing issues after three months. Thankfully, it comes with
a ten-year warranty, so it should be easy to get sorted, right?&lt;/p&gt;
&lt;h3 id=&#34;warranty-woes&#34;&gt;Warranty woes&lt;/h3&gt;
&lt;p&gt;I looked at Cooler Master’s warranty, and for issues within the first two years
you have to deal with the retailer. That would be Amazon in my case. So I looked
at Amazon’s information on warranty issues. Their policy is that if it’s more
than 30 days since purchase, you have to send it off to a third-party repair
center and wait for them to diagnose and try to repair it. Here’s the kicker:&lt;/p&gt;
&lt;blockquote&gt;
&lt;p&gt;Usually repairs take up to 20 business days (including delivery time), but
could take slightly longer&lt;/p&gt;
&lt;/blockquote&gt;
&lt;p&gt;I use the computer for work, have upcoming LAN parties to go to, and generally
can’t do without it for an entire month. That’s assuming they reproduce
the issue: the PSU fan only turns on when it reaches a certain temperature,
so if you just plug it in briefly it won’t exhibit any symptoms.&lt;/p&gt;
&lt;!--more--&gt;
&lt;p&gt;If I was going to do a warranty return, I’d need to buy a new PSU first to
use while this one was away. If I’m spending £100+ on a PSU, then I’d be getting
a better one that doesn’t have known issues with the fans. So when the Cooler
Master eventually got returned I’d have no use for it. What a waste.&lt;/p&gt;
&lt;p&gt;So the warranty is about as much use as a chocolate teapot. Good to know, I
guess. If I wanted decent service, I should have probably used a real retailer,
not Amazon. Lesson learnt.&lt;/p&gt;
&lt;h3 id=&#34;doing-some-research&#34;&gt;Doing some research&lt;/h3&gt;
&lt;p&gt;If the warranty is useless to me, maybe I should just void it and try to fix it
myself. I did some research online. Most of the results went like this:&lt;/p&gt;
&lt;blockquote&gt;
&lt;p&gt;if you’re not a trained professional you should not be opening up your PSU
at all. There’s a lot of current that goes through it which will seriously
hurt/main/kill you&lt;/p&gt;
&lt;/blockquote&gt;
&lt;p&gt;or&lt;/p&gt;
&lt;blockquote&gt;
&lt;p&gt;it’s time consuming and potentially dangerous&lt;/p&gt;
&lt;/blockquote&gt;
&lt;p&gt;or some other variety of doom and gloom. There were some actually useful results
sprinkled in, though. &lt;a href=&#34;https://smallformfactor.net/forum/threads/cooler-master-v850-sfx-psu-fan-swap.17294/&#34;&gt;A post on the smallformfactor.net forums&lt;/a&gt;
details someone swapping out the fan on the 850W version of the same power
supply because it was too noisy. It looks like the fan connector in the PSU
is a two-pin connector, and they just used an off-the-shelf adapter to convert
the standard four-pin case fan connector. It sounded a bit annoying to make
it all fit, though.&lt;/p&gt;
&lt;p&gt;&lt;a href=&#34;https://old.reddit.com/r/sffpc/comments/1h97sz6/cooler_master_v850_sfx_noctua_fan_swap/&#34;&gt;A similar post on reddit&lt;/a&gt;
showed basically the same upgrade, but identified the connector as a 2.54mm
JST-XH. They crimped their own connector on, which feels a lot better than
using a bulky connector. I do have a crimping set for JST connectors, but I
absolutely hate doing them because they’re so fiddly and annoying. I’m not sure
if I trust one of my crimps inside a power supply, either.&lt;/p&gt;
&lt;p&gt;Looking at the pictures in those posts, I identified the fan as an Ong Hua
&lt;code&gt;HA9215VH12FD-F00&lt;/code&gt;. I searched to see if I could see any specifications for it.
I couldn’t. But what I did get back as my first result was another Reddit post,
this one titled &lt;a href=&#34;https://old.reddit.com/r/sffpc/comments/1b4j6vr/getting_rid_of_a_ha9215sh12fdf00_fan_from_your_psu/&#34;&gt;“Getting rid of a HA9215SH12FD-F00 fan from your PSU”&lt;/a&gt;.
It says something about the quality of a component when the first result
is a post about getting rid of it because it’s annoying&lt;sup id=&#34;fnref:2&#34;&gt;&lt;a class=&#34;footnote-ref&#34; href=&#34;#fn:2&#34; role=&#34;doc-noteref&#34;&gt;2&lt;/a&gt;&lt;/sup&gt;.&lt;/p&gt;
&lt;p&gt;All of these mods seemed easy enough, and I’m reasonably confident in my ability
to both discharge and avoid touching capacitors, so I probably wouldn’t die.
I ordered a Noctua NF-A9x14 fan and some pre-made JST-XH connectors and waited
for them to arrive.&lt;/p&gt;
&lt;h3 id=&#34;upgrade-time&#34;&gt;Upgrade time&lt;/h3&gt;
&lt;aside class=&#34;warning&#34;&gt;
  &lt;div&gt;
    &lt;h5&gt;Warning&lt;/h5&gt;
    &lt;p&gt;Like the Reddit keyboard warriors said, the stuff inside PSUs is dangerous.
Try not to kill yourself or release the magic smoke if you do this.
I’m not taking responsibility for your actions!&lt;/p&gt;
  &lt;/div&gt;
&lt;/aside&gt;
&lt;p&gt;The replacement parts arrived one evening, so when I turned the computer off
for the night I unplugged it from the mains, held the power button down for
a while, and left it overnight for good measure. The next morning I popped
open the case, disconnected and removed the PSU, gleefully tore the
“warranty void if removed” sticker off, and opened it up.&lt;/p&gt;
&lt;p&gt;Removing the fan was simple: unplug the JST connector and undo the screws
holding it to the outer panel. I confirmed that my JST connectors were the
right size, then started surgery on the Noctua fan. I carefully removed the
heatshrink, cut off the normal fan connector, and separated out the four wires.
A quick check of their &lt;a href=&#34;https://faqs.noctua.at/en/support/solutions/articles/101000081757-what-pin-configuration-do-noctua-fans-use-&#34;&gt;FAQ&lt;/a&gt;
confirmed the wiring colours: black was ground, yellow +12V, and blue and
green used for speed control (which we’re not using in this instance). I clipped
the blue and green wires off near the hub so they wouldn’t be in the way, then
cut the yellow and black wires down to length, and attached the JST connector
with a solder seal:&lt;/p&gt;
&lt;figure class=&#34;image full&#34;&gt;
  &lt;picture&gt;
      &lt;source srcset=&#34;https://chameth.com/fixing-a-loud-psu-fan-without-dying/fans.avif&#34; type=&#34;image/avif&#34;/&gt;
      &lt;source srcset=&#34;https://chameth.com/fixing-a-loud-psu-fan-without-dying/fans.webp&#34; type=&#34;image/webp&#34;/&gt;
      &lt;img src=&#34;https://chameth.com/fixing-a-loud-psu-fan-without-dying/fans.jpg&#34; alt=&#34;Two fans side by side on a mouse mat: a black fan with a short power connector, and a beige-and-brown fan with transparent solder seals over the joins in its power connector. The mouse mat has a shiny patch near the solder seals.&#34; loading=&#34;lazy&#34; width=&#34;1600&#34; height=&#34;887&#34;/&gt;
  &lt;/picture&gt;
  &lt;figcaption&gt;&lt;p&gt;Old fan, new fan, burnt mouse mat&lt;/p&gt;
&lt;/figcaption&gt;
&lt;/figure&gt;
&lt;p&gt;In the process I discovered my mouse mat doesn’t like being hit with a heat gun.
Whoops. The solder seals are great: the solder in the center melts to form an
electrical connection, the parts at the end grip the cable to provide mechanical
strength, and the whole thing acts like heatshrink and keeps the connection
insulated. A lot less fiddly than crimping JST connectors, and a lot smaller
and cheaper than an adapter.&lt;/p&gt;
&lt;p&gt;I installed the fan and reassembled the PSU. Then undid it all and tried again,
as apparently the face the fan mounts to isn’t quite symmetrical and I’d
installed the fan upside down. Connected everything back up, plugged the
computer in, booted it up, and… nothing. The PSU doesn’t actually power the fan
until it hits a certain temperature. I figured putting it under load would
probably heat it up, so ran a graphics benchmark a few times. Eventually the
fan spun up. Huzzah.&lt;/p&gt;
&lt;figure class=&#34;image full&#34;&gt;
  &lt;picture&gt;

      &lt;source srcset=&#34;https://chameth.com/fixing-a-loud-psu-fan-without-dying/installed.webp&#34; type=&#34;image/webp&#34;/&gt;
      &lt;img src=&#34;https://chameth.com/fixing-a-loud-psu-fan-without-dying/installed.jpg&#34; alt=&#34;Computer with the side panel removed, with a Noctua fan visibly spinning inside the PSU, next to another Noctua fan spinning above the CPU.&#34; loading=&#34;lazy&#34; width=&#34;1280&#34; height=&#34;720&#34;/&gt;
  &lt;/picture&gt;
  &lt;figcaption&gt;&lt;p&gt;Soon the entire computer will be beige and brown&lt;/p&gt;
&lt;/figcaption&gt;
&lt;/figure&gt;
&lt;h3 id=&#34;peace-at-last&#34;&gt;Peace at last&lt;/h3&gt;
&lt;p&gt;I measured the sound of the new fan: 43 dB. That’s a decrease of 20 dB. Due
to the weird logarithmic properties of the dB scale that no one understands,
that means it sounds about 4 times quieter to human ears. Big improvement!&lt;/p&gt;
&lt;p&gt;It’s worth pointing out this isn’t a straight one-to-one upgrade. I don’t know
the specs of the old fan in terms of airflow, and I’m just assuming that the
Noctua will be good enough by virtue of being a decent fan. They also behave
slightly differently as the power ramps up: the stock fan starts spinning
at a lower voltage than the Noctua, which needs around 7V to get started
properly&lt;sup id=&#34;fnref:3&#34;&gt;&lt;a class=&#34;footnote-ref&#34; href=&#34;#fn:3&#34; role=&#34;doc-noteref&#34;&gt;3&lt;/a&gt;&lt;/sup&gt;. I don’t think this will be an issue, as it’s effectively just
putting a small step at the lower end of the fan curve. It might shorten the
overall lifespan of the PSU, but from my point of view it failed after four
months, so any extra time is a bonus.&lt;/p&gt;
&lt;p&gt;I recorded some before/after audio, so you can hear the difference. I think
there’s some amount of volume normalisation going on, so it’s not quite as
stark a difference as in person, but it’s still noticeable.&lt;/p&gt;
&lt;figure class=&#34;full&#34;&gt;

  &lt;figcaption&gt;Audio sample from the new fan&lt;/figcaption&gt;
&lt;/figure&gt;
&lt;p&gt;And if you couldn’t hear it, here’s a visual representation:&lt;/p&gt;
&lt;figure class=&#34;image full&#34;&gt;

  &lt;/picture&gt;
  &lt;figcaption&gt;&lt;p&gt;Side-by-side comparison of the audio clips&lt;/p&gt;
&lt;/figcaption&gt;
&lt;/figure&gt;
&lt;p&gt;The whole upgrade took about an hour (less time than writing this post about
it!), and I even managed to avoid killing myself.&lt;/p&gt;
&lt;div class=&#34;footnotes&#34; role=&#34;doc-endnotes&#34;&gt;

&lt;ol&gt;
&lt;li id=&#34;fn:1&#34;&gt;
&lt;p&gt;Opening the case and sticking my ear near to various components. High-tech
stuff. &lt;a class=&#34;footnote-backref&#34; href=&#34;#fnref:1&#34; role=&#34;doc-backlink&#34;&gt;↩︎&lt;/a&gt;&lt;/p&gt;
&lt;/li&gt;
&lt;li id=&#34;fn:2&#34;&gt;
&lt;p&gt;On closer inspection it’s actually a slightly different model — there’s
an &lt;code&gt;S&lt;/code&gt; not a &lt;code&gt;V&lt;/code&gt; in the middle there — but I’m going to assume that doesn’t
change much on the quality/noise front. &lt;a class=&#34;footnote-backref&#34; href=&#34;#fnref:2&#34; role=&#34;doc-backlink&#34;&gt;↩︎&lt;/a&gt;&lt;/p&gt;
&lt;/li&gt;
&lt;li id=&#34;fn:3&#34;&gt;
&lt;p&gt;It then keeps spinning down to about 5V or so, it just needs enough power
to initially get started. &lt;a class=&#34;footnote-backref&#34; href=&#34;#fnref:3&#34; role=&#34;doc-backlink&#34;&gt;↩︎&lt;/a&gt;&lt;/p&gt;
&lt;/li&gt;

  &lt;/picture&gt;
  &lt;figcaption&gt;&lt;p&gt;This, dear reader, is a hammer. It is almost entirely irrelevant to the article. Enjoy.&lt;/p&gt;
&lt;/figcaption&gt;
&lt;/figure&gt;
&lt;p&gt;I presume everyone is familiar with the idiom “if all you have is a hammer,
everything looks like a nail”. If not, well, there it is. It’s generally
used pejoratively about being single-minded, but I think it also gives a glimpse
into something more interesting: mental and perceptual sets.&lt;/p&gt;
&lt;p&gt;Before I explain, let me tell you a story about a person who bought a 3D printer&lt;sup id=&#34;fnref:1&#34;&gt;&lt;a class=&#34;footnote-ref&#34; href=&#34;#fn:1&#34; role=&#34;doc-noteref&#34;&gt;1&lt;/a&gt;&lt;/sup&gt;.
When they were first thinking about getting one, they weren’t sure if it was
worth it. They could print a few board game accessories, but then what? After
they got it, though, a whole new world opened up: everywhere they looked there
were opportunities to improve things by adding 3D printed plastic. Broken
appliances were repaired with 3D printed parts, all sorts of shelves,
organisers, hooks and other things were made. But when they talked about this
to other people, most often the response was “That’s nice, but I don’t think
I’d use one”. How could they not see the truth in all its glorious layer lines?!&lt;/p&gt;
&lt;p&gt;The answer is in the concept of a ‘set’&lt;sup id=&#34;fnref:2&#34;&gt;&lt;a class=&#34;footnote-ref&#34; href=&#34;#fn:2&#34; role=&#34;doc-noteref&#34;&gt;2&lt;/a&gt;&lt;/sup&gt;, and instead of trying to explain it,
I’m just going to quote &lt;a href=&#34;https://en.wikipedia.org/wiki/Set_(psychology)&#34;&gt;Wikipedia&lt;/a&gt;:&lt;/p&gt;
&lt;blockquote&gt;
&lt;p&gt;In psychology, a set is a group of expectations that shape experience by making
people especially sensitive to specific kinds of information. A perceptual set,
also called perceptual expectancy, is a predisposition to perceive things in a
certain way. […] A mental set is a framework for thinking about a problem.
It can be shaped by habit or by desire. Mental sets can make it easy to solve
a class of problem, but attachment to the wrong mental set can inhibit
problem-solving and creativity.&lt;/p&gt;
&lt;/blockquote&gt;
&lt;p&gt;This perfectly captures what happened. They’d developed a ‘3D printing mental set’:
a predisposition to see problems that can be solved with their &lt;del&gt;hammer&lt;/del&gt; 3D
printer. Once I started noticing this pattern, I started seeing it all over
the place.&lt;/p&gt;
&lt;!--more--&gt;
&lt;h3 id=&#34;sets-at-work&#34;&gt;Sets at work&lt;/h3&gt;
&lt;p&gt;Aside from the “could this be improved with some 3D printed plastic” perceptual
set, I’ve noticed a couple of other sets: DIY, and writing puzzles.&lt;/p&gt;
&lt;p&gt;DIY is probably the most obvious one. Once you become a little familiar with the
basics of what you can fix and how, it seems like you start noticing the
opportunities more. Before, you might have ignored that loose door handle, but
now you notice it and realise with a screwdriver and a sex bolt&lt;sup id=&#34;fnref:3&#34;&gt;&lt;a class=&#34;footnote-ref&#34; href=&#34;#fn:3&#34; role=&#34;doc-noteref&#34;&gt;3&lt;/a&gt;&lt;/sup&gt; you can
fix it and stop it coming loose again anytime soon.&lt;/p&gt;
&lt;p&gt;As you do more things, you build up your set of mental sets as well. You learn
how to attach things to different types of walls, how to safely work with
electricity, and so on, and suddenly installing a new outside light goes from
a seemingly complex job to just exercising some of those concepts you’re already
familiar with.&lt;/p&gt;
&lt;p&gt;This works across ‘disciplines’ as well: I wanted to automatically cool
a room down, using a fan in the window to blow in cool air. The 3D printing
mental set gave me a way to make it physically go where I wanted it to, the
home automation set gave me a plan for how to automate it, and the electricity
set helped me figure out how to wire in the relay. It sounds a bit stilted when
I spell it out like that, but the catch is I didn’t have to sit down and work
any of this out. I was already primed to think in a certain way. I had a whole
selection of hammers, and could pick the right combination of them to beat
this particular nail&lt;sup id=&#34;fnref:4&#34;&gt;&lt;a class=&#34;footnote-ref&#34; href=&#34;#fn:4&#34; role=&#34;doc-noteref&#34;&gt;4&lt;/a&gt;&lt;/sup&gt;.&lt;/p&gt;
&lt;p&gt;Puzzles are a bit different. I enjoy taking part in puzzle hunts&lt;sup id=&#34;fnref:5&#34;&gt;&lt;a class=&#34;footnote-ref&#34; href=&#34;#fn:5&#34; role=&#34;doc-noteref&#34;&gt;5&lt;/a&gt;&lt;/sup&gt;, and at
first I was bewildered at how the authors came up with all the puzzles. After
I started thinking about writing some myself, though, I began to notice all
kinds of things that could maybe be turned into a puzzle: a specialised
database, or a song with repetitive lyrics, or set of things with unique ID
numbers. Writing the actual puzzles is still tricky, but once you’ve equipped
the “look out for puzzle material” perceptual set it’s much easier to gather
a range of ideas.&lt;/p&gt;
&lt;p&gt;For example, one puzzle I wrote came about because I stumbled upon
&lt;a href=&#34;https://archive.org/details/patrick-stewarts-cowboy-classic-sampler&#34;&gt;Sir Patrick Stewart’s Cowboy Classic Sampler&lt;/a&gt;&lt;sup id=&#34;fnref:6&#34;&gt;&lt;a class=&#34;footnote-ref&#34; href=&#34;#fn:6&#34; role=&#34;doc-noteref&#34;&gt;6&lt;/a&gt;&lt;/sup&gt;.
I think everyone will agree that it’s a fairly unique collection. I tied some
samples of the songs together with some screen captures of Sir Patrick as Picard
in Star Trek: The Next Generation, and puzzlers had to find the season and
episode numbers of the pictures, then use those numbers to select a track and a
word from that track in the audio mix. Those words spell out a question, and the
answer to that question is the answer to the puzzle.&lt;/p&gt;
&lt;p&gt;There were other hints mixed in to point you in the right direction, it wasn’t
quite as opaque as it might sound! But the point is without being in that
“puzzle finding” mindset when I came across the album, there’s no way I could
have come up with that puzzle. Like with the fan, I was primed to think a
certain way, and managed to create something I otherwise would have struggled
with.&lt;/p&gt;
&lt;h3 id=&#34;the-curse-of-noticing-things&#34;&gt;The curse of noticing things&lt;/h3&gt;
&lt;p&gt;Figuring out how to make stuff isn’t the only place sets appear, though.
Perceptual sets are about how we perceive things. When you read something
with lots of bullet points, em-dashes, and the word “delve” do you automatically
think it’s LLM generated?&lt;sup id=&#34;fnref:7&#34;&gt;&lt;a class=&#34;footnote-ref&#34; href=&#34;#fn:7&#34; role=&#34;doc-noteref&#34;&gt;7&lt;/a&gt;&lt;/sup&gt; Then you have an LLM text perceptual set! It’s
kind of annoying, as it’s difficult to “turn off” and stop noticing these
things once you’ve seen them. Similarly, I think I have a “bad grammar” set.
I know it doesn’t bother a lot of people, but if I’m reading a book and there’s
a rogue apostrophe it will throw me right out of the moment. It’s like tripping
up when walking and being torn out of a daydream. There’s some use to these —
being able to notice grammar errors easily helps with my writing — but for
the most part they’re a negative input: they point out things are broken or
bad.&lt;/p&gt;
&lt;p&gt;The “edge case set” takes this to another level. After about 20 years of writing
software&lt;sup id=&#34;fnref:8&#34;&gt;&lt;a class=&#34;footnote-ref&#34; href=&#34;#fn:8&#34; role=&#34;doc-noteref&#34;&gt;8&lt;/a&gt;&lt;/sup&gt; I have a finely honed ability to spot problems. Give me something to
implement and my brain will immediately rattle off all the different edge cases
and under-specified parts. Then some other bit of my brain gets the job of
deciding which we actually care about, which are worth raising, and so on.
It’s definitely useful to spot them up-front, rather than when you’re deep in
the weeds implementing something, and tends to make everything go a lot smoother
if you can hammer the major ones out when planning work. It doesn’t turn off
after work though; it comes up when reading board game rule books, or
descriptions of the magic system in fantasy novels, or news reports, and so on.
It’s a lot less useful then.&lt;/p&gt;
&lt;p&gt;Speaking of news reports, here’s a fun one: Gell-Mann amnesia is a cognitive
bias where even when you critically assess media reports about something you’re
knowledgeable about (say, technology), you continue to trust similar reporting
in other areas (say, medicine). But once you know about Gell-Mann amnesia, you
might start to actively notice when it happens. You scoff at the article about
how the Internet is a “series of tubes” and then start reading the next one
about a cancer treatment, but — wait a minute — your Gell-Mann amnesia set
kicks in. I’m not sure what you then do with this information. Dismiss basically
all the media and news as useless? It’s honestly pretty annoying.&lt;/p&gt;
&lt;h3 id=&#34;the-meta-set&#34;&gt;The meta set&lt;/h3&gt;
&lt;p&gt;I’ve had this blog post on my ideas list since I first noticed the “3D printing
mindset”. I didn’t know sets were an actual thing, and I didn’t have most of
the examples I do now. As time went on with this idea rattling around in the
back of my head, I started noticing the patterns come up more and more. There’s
lots of more examples I didn’t include because I didn’t want to just write a
listicle of mental patterns. But the fact that I noticed them all seems to mean
that I’ve developed a set set, or a meta-set, if you will. It’s fascinating
to think about how all this happens inside our mushy bag of neurons, but
also a bit terrifying. If thought processes are that malleable, what stops you
accidentally breaking them? Actually, thinking about things like Q-Anon, flat
earthers, and a lot of contemporary “politics”, maybe that’s quite easy to do?&lt;/p&gt;

&lt;ol&gt;
&lt;li id=&#34;fn:1&#34;&gt;
&lt;p&gt;Surprise! I am that person. Bet you didn’t see that coming! &lt;a class=&#34;footnote-backref&#34; href=&#34;#fnref:1&#34; role=&#34;doc-backlink&#34;&gt;↩︎&lt;/a&gt;&lt;/p&gt;
&lt;/li&gt;
&lt;li id=&#34;fn:2&#34;&gt;
&lt;p&gt;I feel like they should have consulted the mathematicians and/or computer scientists before they picked a name. &lt;a class=&#34;footnote-backref&#34; href=&#34;#fnref:2&#34; role=&#34;doc-backlink&#34;&gt;↩︎&lt;/a&gt;&lt;/p&gt;
&lt;/li&gt;
&lt;li id=&#34;fn:3&#34;&gt;
&lt;p&gt;Yes, that’s a real thing. No, I won’t ever use any of the alternative names for it. &lt;a class=&#34;footnote-backref&#34; href=&#34;#fnref:3&#34; role=&#34;doc-backlink&#34;&gt;↩︎&lt;/a&gt;&lt;/p&gt;
&lt;/li&gt;
&lt;li id=&#34;fn:4&#34;&gt;
&lt;p&gt;OK, I’ve strained the metaphor enough. I’m sorry. I’ll stop. &lt;a class=&#34;footnote-backref&#34; href=&#34;#fnref:4&#34; role=&#34;doc-backlink&#34;&gt;↩︎&lt;/a&gt;&lt;/p&gt;
&lt;/li&gt;
&lt;li id=&#34;fn:5&#34;&gt;
&lt;p&gt;If you’re not familiar, a puzzle hunt is a competition where you try to solve puzzles faster than other teams. The sort of puzzles involved are perfectly described by this quote from Mike Develin: “Imagine a word search. Now imagine you aren’t told what words to look for. Now imagine you aren’t told it’s a word search. Now imagine it isn’t a word search.” &lt;a class=&#34;footnote-backref&#34; href=&#34;#fnref:5&#34; role=&#34;doc-backlink&#34;&gt;↩︎&lt;/a&gt;&lt;/p&gt;
&lt;/li&gt;
&lt;li id=&#34;fn:6&#34;&gt;
&lt;p&gt;Go and give it a listen. I’ll wait. &lt;a class=&#34;footnote-backref&#34; href=&#34;#fnref:6&#34; role=&#34;doc-backlink&#34;&gt;↩︎&lt;/a&gt;&lt;/p&gt;
&lt;/li&gt;
&lt;li id=&#34;fn:7&#34;&gt;
&lt;p&gt;I hereby certify all my em-dashes are hand-crafted. Relatedly, Claude Code keeps writing comments that use hyphens when they should actually be em-dashes. Maybe they’ve trained it to avoid them? &lt;a class=&#34;footnote-backref&#34; href=&#34;#fnref:7&#34; role=&#34;doc-backlink&#34;&gt;↩︎&lt;/a&gt;&lt;/p&gt;
&lt;/li&gt;
&lt;li id=&#34;fn:8&#34;&gt;
&lt;p&gt;I just made myself sad by working this out. I still feel young at heart! … Or maybe that’s cholesterol? &lt;a class=&#34;footnote-backref&#34; href=&#34;#fnref:8&#34; role=&#34;doc-backlink&#34;&gt;↩︎&lt;/a&gt;&lt;/p&gt;
&lt;/li&gt;
&lt;/ol&gt;
