My overclocked Q6600 has been running at 73-75 degrees 24/7 for several months now without any errors while folding. Ditto with my Q9550 while I had it, ran 75 degrees 24/7 with none errors.

Well Zero82z , I guess we'll have to agree to disagree.

I'm reasonably sure if I asked an Intel engineer about it , he'd say 7 degrees above spec is too hot.





edit :

I've done some more reading on this.Someone has talked to some intel engineers.

Apparently , the thermal spec on an Intel CPU is not in fact the maximum allowable temp . So It looks like I was wrong.My apologies.

In my defense , Intel changed the definition of 'thermal specification' . In all other electronic components , the themal spec is the max temp.

Learn something new everyday.

Based on what I have read from Intel's technical documents, the thermal spec is not the maximum temperature but the value of Tcase the CPU is specified to run at under normal operating conditions and with the stock heatsink.

In any case, a core temperature of 75C is not 7 degrees above the thermal spec, and in fact is most likely below it by a fair amount. I have seen reports of people measuring 20C differences between the core temperature and Tcase.

Yep.

What I saw said that the 'thermal specification' is not just Tcase under normal conditions but it's actually the average Tcase , of a 'test group' , at a given TDP.

So it's really an insignificant value.I won't mention it again.

I've also seen multiple sources suggest that TjMAX -15 C is no problem , so yea I was wrong forsure.The OP's temps are fine.

The actual thermal trip point is about 25C above Tjmax as a matter of fact. That is the temperature that will trigger the CPU's thermal shutdown. Tjmax itself is a perfectly safe temperature for the CPU to run at, although undesirable because of the thermal throttling.
