Q6600 Temps - 2 cores 3-4c hotter all the time

post #1 of 7
Thread Starter 
Q6600 @ 3.05Ghz CPU voltage 1.275 (could be slightly higher I am not home ATM to get the exact number) I do know I selected the voltage and kept it pretty low based on what I read in the forums was the default voltage.

I have a Q6600 with a Zalman 9700Led HS/Fan in an Antec P180 case running 2 120mm exhaust fans in the case (back and top) 1 120mm fan intake fan. The Zalman is blowing directly into the rear exhaust fan on the case. I used the Thermal Compound that came with the Zalman and applied a nice even thin layer over the CPU, but not around the very outer edges.

Here's a pic of my system if it helps

While installing the Heatsink on the CPU it did twist a little more then I would have liked, but I screwed it down anyway.

The Zalman is running at full speed as well as the rest of the fans in the upper chamber of the P180.

Ambient Temp is around 75-80F (23-26c) degrees in the room. My house has crappy insulation and with 3 PC's running in the room it's hard to get it any lower in the summer time.

CPU Temps are being reported by CORE TEMP:

Idle
Core 1 - 43-44c
Core 2 - 43-44c
Core 3 - 40c
Core 4 - 40c

No matter what I do Cores 1 and 2 are always very close in temps, but they are also almost always 3-4c above Cores 3 and 4.

Should I remove my Zalman clean off the old Thermal grease and re-apply some AC5 and reseat everything ? This system is only 6 days old.

The highest temps I have gotten any core under 98-99% load is 63c, should I be worried at all about this 3-4 degree difference ?

Thanks in advance for any advice.

I wouldn't worry about that.
On my quad it's actually cores 1 & 3 that are always hotter than the others.
In your case I would hazard a guess that since it's basically two E6600's smooshed together, one die runs hotter than the other?

Don't worry, cores 1 and 2 are on a different die than the others and a temp differential of 3-4C is normal. Those 2 cores are usually under a little more load than the others since they are the "first" ones, so they are generally a little hotter. If you run a program like TAT or Orthos all of the temps should even out at 100% load.

Thanks for the replies, makes me feel better

It's my first OC and I just wanted to make sure everything was running within spec.

Your fine. Some cores do run hotter than others but if it gets too hot you should try reapplying thermal paste and reseating your HSF. Maybe the paste didn't spread over the second core too well.

Here is a good read if you are interested in learning more about the temperature sensors in your chip:
