Core Temp variation

[jcamel24]

Just for reference, how much of a temp. variation should there be on an i7-2600k overclock? As of now, I'm at 4.4Ghz with max temps of 59, 64, 64, and 67. Should they be more even? Almost 10C seems like quite a difference.

Edit: Updated temps after longer testing

8 C difference is not unusual.

Two possibilities:
One of your thermal sensors is inaccurate.
The thermal paste is not uniformly spread over the cooler contact surface.

Thermal sensors are notoriously variable. For critical OC attempts they must be calibrated before being relied on. This involves loading the processor at 100% and then at incrementally lower loads through 5-10 stages. Since the errors may not be linear you need to find the variations at several points of load. Using Real Temps and Prime95 you can do this. However for most of us it is not necessary. From your post I would say the 64 reading is probably most accurate. What are the readings at 100% load after a few minutes?

 

[jcamel24]

Those were the load temps after 1 hour of Prime95. 4.4Ghz, no voltage changes, Corsair A70 running @1600 rpm. Did 15 min @4.5 Ghz, had same temps.

Sounds like you are good to go.
