what the purpose/advantages of openbsd ? (completly open minded question)

The entire operating system is extremely well documented and thought out. Everything is done the traditional Unix way, so you don't end up with problems from churning half-baked subsystems. It's also routinely + repeatedly security audited. If they can't maintain quality+security for some subsystem (e.g., their bluetooth stack), then they delete it.

I run it on my router. I've had zero problems in many, many years.

I have similar but not so extreme inclinations towards fan noise. I settled to build my desktop with a simple NZXT case, intel 8th gen CPU running Arch Linux with CPU governor set to Performance. The pSU is an ATX power supply that is rated for 750W, while I could barely get to half that with full load(which means PSU’s fans almost never need to spin up). The CPU is cooled by an oversized NH D-15 Noctua air cooler wi…

Undervolting/power limiting could work well as well. The latest gen CPUs apparently get like 95% of their performance when limited to only like 1/3 of the max power.

105 instead of 170W TDP get you 95% on a 7950X, so ~60%.

I run a pretty-much-fanless Arch Linux desktop. It’s a Lenovo m920q I bought second hand, ex lease on eBay. Super simple, no fuss at all. Comes with remote KVM in the motherboard. (The security implications are totally probably fine) It’s totally silent in normal use. (Go web dev mostly) Occasionally the fans will start up to alert me to the fact that I’ve landed on some social scummy website that’s crammed with 20 b…

I've had my eye on these 1 liter PCs to replace my aging Haswell Xeon based server (Dell PowerEdge T20). My system still works great and is completely silent but it's very old and a second one I had died recently. I use external hard drives so I really don't need a traditionally sized system.

I'd need to squeeze 64GB of ram in though, as the 32 I have currently is occasionally limiting depending on the VMs I'm running.

Earlier quoted context omitted.

One option here is to wire up the fans to run at 7V (connect negative to 5V line), or even 10V (by connecting to -5V and +5V). But getting software control to bump that up to 12V when needed could take some extra steps/hardware. But if you use the system lightly enough, it’ll be cooler in its norma state and might not need the extra cooling oomph. Heat kills!

That's not necessary anymore, the fans are either PWM or voltage controlled by software in every modern system. The noctua fans are also rather quiet by default.

I made my PC basically silent by swapping out the included Corsair case fans with Noctuas. I can only hear it if the CPU or GPU crank up to full load.

Unfortunately the author won't be able to comment on HN since he got banned 10 years ago. As a result, he created another site some might know https://lobste.rs https://jcs.org/2012/06/13/hellbanned_from_hacker_news

Crazy to see that someone has 18,000+ karma points and only posted 6 times in the last 10-years.

I confess I am somewhat impervious to bad kerning myself. I thought about fixing that (there's online exercises that one can take) but then I realized that there's potentially so much bad kerning out there I would be making my life more miserable for no reason.

Thanks, I didn’t know this one :)
