I am using the Thermalright Ultra 120 Extreme(Lapped) on an E6600(Lapped), but I get weird temps. My Core Temps are both 29C Idle, but my CPU temp is 42C. Should I even worry about the CPU temp and just worry about the core temps? I'm looking to hit 3.6 on it, but I know if I do, the CPU Temp will be very high, while the Core Temps will be fine. Thanks.
