Drastic difference in core temperatures

post #1 of 4
Thread Starter 
Is it normal for one core to run much cooler than the rest? This has been the case with two coolers, a Hyper 212+ and a Noctua NH-D14. I've tried remounting several times, so I do not believe the issue lies with how the coolers were mounted or how TIM was applied.

Here are results from 10 runs of LinX AVX:

That's not bad at all.

I sometimes have a 14°c delta between cores.

That's not bad. I have a 9 degree difference between max temperatures of two of my cores at full load. It's nothing to be worried about.

Same deal with me, 1 core is 9-10c cooler than the others.
