Let's talk about tips and tricks for cleaning.
Just wanted to start a discussion about how to keep case fans and heatsinks running smoothly. I'll start:
Whenever I notice dust building up(usually monthly), I'll hit it with canned air. This is just a surface clean, though, and can push dust further into the case. To prevent buildup inside, every year I'll do a thorough cleaning and use an air compressor (250psi instead of canned air's wimpy 75psi) to blast the dust out of the heatsink. It's also a nice opportunity to check for things like blown caps or loose connectors.
For some reason the dust on the case fans doesn't blow off as easily as the dust in the case, so I usually end up scrubbing it off with an old toothbrush and 90% isopropyl alcohol.
Power supply fans are always the worst, but just because they're trapped inside their case. Lock the fan in place with a toothpick, then use the same toothbrush and alcohol to get it.
