What are the rest of your system specs? How far is the Q6600 overclocked? Sotck Cooler? Temps?
Usualy about 3 Ghz, however i have put it back to 2.4 and it is better but after a while it still occurs. I had stock cooler but got a new one which is pretty crap to ber honest. Temps are idle at about 45-52. Load i actualy hit 80C but usuasly 75 max
