So I got this CPU early this year, and the fan is making a buzzing sound when it goes above 4000rpm, getting even louder at higher speeds.
Mobo: ASRock A55M-HVS
GPU: HD 7750 Saphire
PSU: CX 500 Corsair
Windows 7 64
It's on a micro ATX case, no extra coolers. Some three days ago I downloaded and installed (the already installed) catalyst software thing from AMD just to make sure all my stuff was updated.
