LMFAO!
Let it build up with dust… by the time you see any performance hit, it is time to build new anyway.
It will just overheat like all hell if you OC. This one I know. Gutting a house and leaving your computer running in the next room tends to suck in a fuckton of cellulose.
Also, have you guys ever opened up a computer with heavy smokers in the house? Back when I actually used to help people with computers I opened up this guys computer and it was covered in tar and nasty shit. Like it was all caked in the fans and everything. It was absolutely revolting.
In highschool one of my buddies that I use to game with (RainbowSix ladder matches! YAY) cleaned his computer with a paintbrush. I think I laughed at him for about a week straight, only in person however since his computer wasn’t exactly in a working state. But then he ended up getting a better computer than I had… it was a 733mhz if I recall. I only had a 333 at the time, I was so jealous 
Electric leaf blower FTW!
I jam the fans with something like a screwdriver, so they cannot over spin. I’ve had fans go bad after spinning them way to fast. I use about 80psi, never had a problem.
Solution to this problem would be to install air filters on the case openings. …
Or get a new case…
some of the comments in here are really funny, but it’s sad how dirty people’s computers get, alot of it happens from them sitting on the ground. If a computer was higher up off the ground these issues would be less likely to happen…
Its amazing how bad some people let them get, when I blow them out I can’t help but think of how dirty their house is and what these people are inhaling, especially the smokers.
:hay:
I tend to think the same thing, but my best friends mom is a hoarder and unbelievably she keeps her computer on top of the desk, it stays clean and gets very little dust/dirt!
My filters do wonders… and I just suck them clean with a vacuum.
