temps idle at 39c with coretemp with good room temp as well with an open case, and loads at around 65-70c......the zalman can handle up to 1.38v with this cpu, anything above it gets too warm for me to even test, this cpu can do 3.3 with the zalman with 1.36v but i kept it at a lower voltage because summer is just burning up my cpu, and for us overclockers thats not too great.....but overall it performs the same as my old tuniq tower 120.
