Temps are ... erm... toasty...

Rig's an I7 920 D0 on an EX58-Extreme.

All runs very happily,so I decided to have a little go at overclocking. And to my pleasant surprise I can get to about 4GHz without too much difficulty with Linpack stable, which is the only real stability test for Intel you can fully rely on.

However, the CPU cores go up to about 90-100C.

That's just way too high - never seen temperatures this high before. I tried re-applying my Thermalright Ultra 120 with a clean layer of AS5 and it cut a few degrees off, but not significantly.

Why the heck are my temps so high on load? Is this even vaguely safe?

Cheers guys.
 
It's because it's Linpack. In the real world situation, I doubt you'll ever see that kind of temps unless you were folding.

Other factors can include your ambient, fans, case airflow, etc

i7s run hot by their nature. If you were to turn off HyperThreading, you'd see a drastic drop in temps. But then you don't get the bragging rights of 8 "cores" :p

If you're on aircooling the temps are not atypical for a 4.0GHz OC. I had about the same on a closed case D0 @ 1.35V (both Vcore and VTT). I basically ended up watercooling my processor, because I cringed at seeing those temps. I attribute the temps to having a concave chip which only made contact on half of the IHS and my Thor's hammer.

The watercooling setup has yielded me 73 (Air conditioned room) to 76 (Air conditioning off) after an hour of linpack. This is not fantastic, but with HT on. I'm not into lapping my CPU, but I'm almost sure that this would help in my case.
