Is a thing of the past now. I just installed a PuraPC computer air filter on my PC. I'll have to let everyone know how it does. it makes sense. check out their site http://www.purapc.com

I'll stick to using compressed air every 1-2 months. BTW,I think it's just wrong to say "this dust RUINS your psu, graphics card cooling fan and main processor cooling fan" I sense a little exaggeration.

Looks completley pointless. Sure dust builds up but unless you dont open your computer for 2 or 3 years at a time you shouldnt have any problems. "Fire Hazard" that made me laugh. The software? Looks more like an alarm clock on a CD. A really dumb product. 8 bucks per filter is not worth it considering the Canned Air costs only tax at those Compusa sales.

One can achieve practically the same air filtration results from a pantyhose! And that too, will disrupt air-flow which will make our poor little fans works harder and less effective. abit is7 i865pe Prescott 2.8ghz @ 4004Mhz 286x14 FSB @ 1144Mhz 512x2 in dual config @ 430mhz PNY 6800 16x1,5vp

I agree with the comments but have to add that a friends psu really blew up. By his description he switched in on and there came quite a flame out of the back of the psu. Luckily nothing caught fire! I looked inside the psu and it was full of dust despite a certain area where everything around was black instead. Obviously there the dust had shortened something. But it was a Pentium3 500MHz and quite old. The only problem is that it's difficult to clean that because I wouldn't suggest to anyone to open the psu!

Most of the time dust will not "short" electronic circuit boards. It can cause heat build up, but never saw it fry a computer. Have replaced many systems (100+) and am suprised how plugged up the power supply and how dirty the guts are, but the computer still works. These were businees computers that are left on 24 hours a day. I think maybe your friend was OC'ing his computer, or forgot about that screwdriver he left in there. :-) Rule #1 Good computers don't go down. Rule #2 There is no such thing as a good computer.
