Hello everyone i have a little problem. I have a core 2 duo cpu e8200 2,66 and the problem is that the first core runs cooler ( core 0) than core 1
Core 1:64 degrees
Core 2:70 degrees
Im asking because the cpu isnt overclocked, actually i underclocked it (well atleast the secound core) to reduce heat output BUT nothing happened. So if someone can help me i would be grateful.

Nothing to help here with, this is perfectly normal, altough it does seem odd at first. It was a known "issue" with C2D and C2Q CPU's. A little difference is always there, its just that this series had 5-6 degrees difference at times. Nothing to worry about.

Intel CPUs have digital sensors on each core. If it has 4 cores, it has 4 sensors and 1 package temperature sensor (temperature of the IHS). Those sensors show different temps based on the cooling for that core. Usually for 4-core processors, the last is the coolest. For dual-cores, the first is usually coolest. AMD doesn't have per-core thermal diodes, so it shows one package temperature.
