But people actually do do this, if for some reason a PC is overheating or the built-in fans are making too much noise. A big fan running slowly moves more air more quietly than a bunch of little fans. I even wired an external DC fan into the PC's power supply once so that I wouldn't have to plug them in separately.

My experience is that this also builds up a pretty spectacular amount of dust inside the case, so regular vacuum cleaning is called for.

that's why you use a custom water cooling loop connected to a car radiator outside.

Or better, connected straight into your pool!

Wait.

Whole home hepa hvac filter on the intake side?

[–] JohnnyEnzyme@piefed.social 1 points 19 hours ago

Yes, something like that!

[–] krashmo@lemmy.world 3 points 19 hours ago (1 children)

Point the fan outwards and pull heat out instead of pushing cool air in. Problem solved.

[–] JohnnyEnzyme@piefed.social 3 points 19 hours ago

Problem not solved. You'll still collect dust wherever there's intake.

The filter is probably the best solution IME.
