An i7 at 33° idle is pretty good, I don't see what the complaint is. My E6700 runs at the same temp idle.
So after just setting up my new rig, I installed Realtemp, and am not liking what I am seeing. I have an 17 920 on an Asus REII with a Mugen 2 in push-pull, and GC-Extreme thermal compound. I was expecting idles around 20 or so, but am getting what I posted below. Loads go into the lower 50's. Do I need to reseat my heatsink, or do you have any other ideas?
Idle?..I'd be more concerned with load temp.
