Question about CPU core temps.

The Matrix · 9 Sep 2012 at 21:58

When looking at the core temps on my CPU at idle ive always noticed that core #0 can be quite a few degrees higher then the other cores, sometimes core #0 can idle at 36 C where as core #2 can be at 27 C. Is their a reason for this ?

As a rough example thats a 7 degrees difference between core #0 and core #2.

This is normal, cores 1 and 3 always run hotter on my 2500k. All down to the quality of the CPU die's.

If its a big difference and just the one core may be uneven distribution of thermal paste on the CPU, may not hurt to re-apply it.

Is the core0 temp much different to the other cores under load?

This was running prime for 30 mins.

Those are bloody good temps for prime.

nothing wrong there at all, fluctuation between cores is common on newer cpu's like I said above

Core #3 on my Q6600 is always 4-8°C cooler than the rest
