Temp Difference between 2 cores (8700k)

[gabby131]

Greetings!

 

As the title says, Core 0 (70 deg C) and Core 3 (82 deg C) have a 10~12 degree C temp difference on heavy loads.

The most recent I did was replace the cooler with an H150i PRO.  I have not reseat the cooler yet (still has the same thermal compound that comes pre-applied).  Just wanna know if this is normal for an overclocked processor - 8700K in particular.  My temps showing below as of typing this.

 

Core 0~72 @ 100%

Core 1~77 @ 100%

Core 2~75 @ 100%

Core 3~83 @ 100%

Core 4~74 @ 100%

Core 5~78 @ 100%

Package~83 @ 100%

 

My verdict is that I need to re-apply the TIM between the die and the IHS (yes, I delid the CPU, but I did not re-lid).

Looking at my the other system with a 5930K, it has the same results (Core 2 highest temp with 10~11 deg C difference from Core 5 temp).

So I assume I need to do some re-seating/re-applying on coolers/TIM?

 

Please advise and thank you for your assistance.

It's normal. Usually it's the result of the TIM application underneath the IHS or a difference in silicon quality between the cores.

Thank you for the responses.  I greatly appreciate!  I will leave it as is then.

'tis quite interesting as well that the Package temp is the temp (or close) of the hottest core.

I just noticed this now after a few CPUs that I own.

Very normal for that cpu
