I overclocked my Q6600 to 3.4 GHz (426x8) and run stable 24+ hours under prime95...
But the temperatures on the 4 cores are different in 2x2 fashion... Namely first 2 cores (0 & 1) are running @ 66 deg at most while at the same time other 2 cores (2 & 3) are running @ 61 deg...
This difference is constant always - during stress-test or gaming... when idle the difference is bit less (2-3 deg)
Is this normal?
Ah, yes, the heat sink is Thermalright IFH-14...
Initially I thought that I have applied the thermal paste (the one which comes with zalman cooler) wrongly because I have this "big" difference... I reinstalled the heat sink again and also used another thermal paste (Innovation Cooling Diamond 7 Carat - very good paste - temp. drops from 72+ to ~66 deg), but I still have this difference in temperature.
any idea why? is the contact surface of the heat sink I need to check (maybe lapping the heat sink)?
thanks!
