Core temp differences

[slugman]

Something that is nagging me and I've seen questions about: differences in core temperature.

At idle I often see something like 32-26-25-26

And load 60-58-57-57. Are differences in temperature like this normal?

Could it be a sign I really do need to reapply the thermal paste?

Yes thats normal.
Not unless the delta was a lot higher

Looks normal to me also. Even see this on water cooling. I think it has something to do with the first core doing all the syncing of the other cores and background tasks etc.

my first core is the cooler one.

What cpu do you have....My theory is un-scientific

He obviously has an Intel CPU since AMD CPU doesn't have individual core sensors (it actually doesn't even have core temperature sensors, the sensors on the north bridge). According to Intel tech documents the internal sensors of the Core/i CPU's are only very accurate at high temperatures (ie. near its thermal limit). At around 50C the sensors can be a 5-10% off, the accuracy increases to within 2% at the thermal limit (TJmax). So your temp of 60C could really be anything from 54-66C which is within the temps of the other cores.
