Thanks for everyones reply.
I oced my e8400 to 3.6 running on 1.2v tested with prime 95 passed with no errors or failures. I also added a 92mm fan in the back vent to suck the air out. right now my idle is at 32c max hit 62 with real temp when playing age of conan at high settings. cpu fan is set running around 30% on nvidia control panel. You guys think its possible to crank it up to 4.0 or do i need a new cooler for that? Thanks in advanced.
