    It could be an idle proccess. This used to happen when an outside proccess thew the idle command to the core, ie the application for overclockers "CPUIdle". Time to use taskmanager to find the culprit.......

    The cores in the CPU are so close together that they directly affect each others temperature. It's unlikely that you'll ever see much difference in temps on the different cores.

    Cores will dissipate heat into each other even with the best heatsink.

    I did the load with SuperPI affinity core 1 and saw about 3-4C only difference

    Is this always supposed to be true? My cores always show a difference of 6-10C. Could something be wrong with mine?

    The thermal monitors in the CPU aren't the most accurate of things and they're probably not calibrated so I wouldn't be too worried. Core1 on my laptop always reads as about 3* higher than core0. The sensors aren't there to give a precise reading of the temperature, they're just a safety measure.
