i7 2600K 2nd core runs 10C hotter ? - Page 3

post #21 of 23
My cores go like this (relative to core 2):

1. +10
2. 0
3. +1
4. +6

It's absolutely the thermal diode internally on these. I tend to trust an average of cores 2 and 3 for temp readings since they're the two most similar cores. TIM re-applications aren't going to change that. It's nothing to worry about. I don't know about yours, but mine even up past 55C or so.

EDIT: Added a pic.

This happened with pea-sized dot spread X23 on my Apogee XT+i7 970. Even with every screw tightened to the same height tested with a ruler in criss-cross motion. It's just the TIM between the core and IHS most of the time. That added to the small discrepancies even the most well-applied TIM creates you may see differences like this.
