air filter; a machine you mean?

don't those add an electric current to dust etc. ? If so, won't that be more dangerous for your computer than dust itself?
Yes, I was talking about the machine. It will not damage the PC in any way (unless you physically put it INSIDE the PC case). If you just leave it in a corner a few feet away from the PC you'll be fine. I have been using one for about 2 years now and it works well.

Best one I found that's specific to your board:

lol, it's by Gigabyte itself!

Only change I would make: Use Prime95 Small FFT insted of the program they used. Also stress test for 6+hrs. And OC in the BIOS only. DO NOT use EasyTune to OC. Also if you installed DES (Dynamic Energy Saver) software provided with the board un install it.
