I overclocked my E6750 last night to 3.36 (420 x 8) to get a performance boost. The problem is when I test the temperatures with Core Temp and TAT I get very different readings. Sometimes Coretemp will be 18C higher than TAT. I am idleing at 22-27C with TAT and around 33-39C with CT. Under stress tests I never pass 60C with TAT but I go into the upper 70s with CT. Of course I want to believe TAT, but don't want to burn up my C2D. Does anyone know which is more accurate, or if they have had similar results? Any help would be greatly appreciated.
