So I did some testing during my Computers downtime the other day, So i popped in my E6600. Cleaned my 120X and the CPU well, Then put on a nice coat of AS5. Then Started overclocking, 460x8 at 1.55v. Idle...16C, Load....28C

Stock Speeds....5C Idle, 10C load.

The Ambient in my room was warm that day. Like me 70-75F.
