i dont know lol, room is 20C, the freezer 7 seems to be doing well, but i think its mostly because there is a 120mm fan venting like 2cm away from it and the 140mm from my psu venting it.
i loaded it with 2X prime95, then 2X cpu burn in with error checking disabled
Get yourself the Intel TAT.
And, it might be easier to use Orthos rather than Prime. Orthos is 2x Prime in one package, so you don't have to fiddle with affinities or anything. It will do it automatically for you.
TAT is good for load, not for monitoring temps. Well, I got where I am with stock power to the CPU. All I really add voltage to is the GMH. by .1V worked like a charm!
