Q6600 Two cores 10C hotter.

[ben16]

Cores 1 & 2 on my Q6600 G0 (not oc'd) are running 10C hotter than cores 3 & 4.
I've tried re-installing the heatsink and thermal paste but the same cores were still just as hot. I checked to see that the CPU and HS were level and they were.

Would I be able to return the CPU as it looks like it's something wrong inside it?

What temp monitoring prog are you using? Give Everest a go....

Try lapping the heatsink and reapply using Arctic Silver 5. Make sure the thermal paster covers the entire Core and not a small line as suggested on Arc5's website. Balance that with not applying too much either!

I'm using CoreTemp.
I don't think it's anything to do with how I'm applying the paste because after the second time I've reattached the HS the same cores are hotter by exactly the same amount.

I have the exact same problem. I have tried reseating the heat sink 4 times, each time in a different orientation (Arctic Cooling Freezer 7) - no change. I think that as the Q6600 is basically 2 E6600s on one chip, the one 6600 has a broken/not-accurate temperature sensor. Mine runs fine even when overclocked to 3GHz. I just use the highest core temperature. I'm fairly sure that it is not my heatsink as programs like Core Temp 0.95 sometimes (just after booting) tell me that the cooler 2 cores are BELOW room temperature. Everest does the same. I hope that makes sense (no time to check it - got to go to town ).

I had an 11c difference on mine before I lapped it.

It's now under 4c, often as little as 1c.

Are there any simple guides on lapping a Q6600?

Have a read through this.
