specs in sig, i also use a ultra 120 extreme. when i first started the comp, the first 2 cores are 43 degrees and the other 2 cores are 35 degrees. my fan mounting clips on my 120 keep coming off because of the giant fan when the case is being put together, so i put a rubber band around the fan instead tro keep it attached to the heatsink. i turn my comp on and the first 2 cores are 61 idle and the other 2 are 49 idle. and 80 load.. WTF happened? did 1 rubber band really increase temps 30 degrees lol
