10°C difference between cores

post #1 of 9
Thread Starter 
Is this normal? I noticed it by a lot of tests/overclocks...

Core 1 and core 2 most of the time difference 10°C...

Does this mean: re-apply the TIM? or is there an other problem?

I used the Zalman-STG1 TIM with the brush to smear it out. Prolly air bubbels??? (I hope) --> When my VF3000F's arrive I'll reapply it with the STG2 anyway (but then use the pea/rice grain method)
I have Chill Factor III also. This or ZM-STG2?

This only happens stressed, in idle the difference is 2-3°C

I get around 7c difference between cores, you can never get them totally equal.

try tightening all corners of the cooler on the retainer again.
Shhh!

I know they will never get equal, but 10°C diff... Will check everything when re-applying TIM

I heard the first core on SB CPUs is often 10°C cooler than the others. I forget if it's just a temp sensor thing or if it really runs 10°C cooler. For me it's Core 1 and 2 that run 10°C cooler than 3 and 4. And they also jump around from 20°C to 30°C to 38°C and back constantly (at idle), while 3 and 4 are pretty solidly between 35 and 38.

Have the same problem on my chip, core 1 is always 10 degrees above the rest, while the rest are more or less equal.

I would figure while stressed the cores temp would equal out, but SB sensors are different then Westmeres. 2 of my cores under idle are ~8C lower and another is ~12C higher, when under load they are all within 2-4C.
post #8 of 9
I have the same with my SB. For me Core 3 seems to run about 6-9c cooler than core's 1 + 2. At the moment they are 30-25-33-29

I think its just how the SB's are i dont think its anything you have done.

my cores seem to be on average 5c difference on average. the first core is mostly the higest and seems to do a fair chunk of the work.
