I was just wondering what everybody does to keep all the dust out of their pc? My fan was running more and more and I took my cover off and then took my cpu fan off and my heat sink was just caked with dust...not good! I vacumed it all out and now my fan only turns on when I am running alot of cpu intensive programs! I was wondering if anyone had any tips or sugestions? I was thinking of trying to put some kind of filters in it but I dont want to block air flow either! Does anyone know of any good filters or something I could buy online to help with this problem?
