if the i7 990X has a Tjunction of 105C and the i7 3930k has a Tcase temp. of 66.8C, which one wud be more stable? I dont understand the concept of Tcase yet

The i7 3930k is faster.

Both Processors will shut off at 105 degrees to try to stop damage.

66.8c is the average temp Intel think under load. They are two different measurements that you have given.

You gave the max for the 990X and the average temp of the 3930k.

Hope that helped :)

It sure did. But i still want to know which one wud be more stable. I have a glycol-cooled system that supplies it at -20C and i want to take my processor as far as i can. The 3930k may be better in most benchmarks but all I want to do is see how far i can take it's clock speed. Frying is NOT a big issue.

I think the 3930k will be hit higher clocks anyway. It's the better all round chip

tcase is the temperature measured from the cpu heat spreader. Tjunction is measured at the cores themselves. core temps will always run hotter, that is where intel chips are designed to throttle back if the temperature gets too hot to protect themselves. so the tjunction max is the theoretical max core temperature before the chip throttles down to save heat and voltage.

Would using speed fan be ideal for checking the core's temperature?

realtemp is the best imo for core temps
