I have an overclock of 3.66GHz on my 920, RAM is running at 1544MHz 7-7-7-19 tRFC-59 CR-1T 2:8. My idle temps are 42c. Is that at about the right temp on idle?

Thanks!

Seems about right to me

What are your load temps like? I used to have that cooler and as good as it is, it didn't like highly clocked quads.

I gets to 80c after about 5min of prime95. I thought that was a little high, but not sure. What cooler are you using now?

Again, seems about right for the cooler. I've just spend an awful lot of money on a WC setup, but load temps are 55-60*C. Idle at mid 30's. At these clocks with the Corsair H50 the temps were reaching mid 80's.

Those temps seem alittle high under load no? ... The Thermal Specification for i7's is 67.9C.

Hmm, Been reading about the web on safe i7 overclocking temps. It seems anywhere 80% of the people in the post ive read say 80c - 85c is a decent stress test load temp.

The central heating is on in the house so room temperatures are pretty warm at the moment.

This is on 1.25v and i ran a small FFTs stress test for 2 hours+ then took this sreener.

(will do a full 8 hour+ stress test overnight)

Unless you're doing video compression or something I'd turn HT off. It'll save you a few degrees off your temps. Also, it's detrimental to some games .

You'd probably get to 4.2 with the same temps with it off.

No no, emulating the extra cores produces more heat. About 8-10c more.
