This is from Newegg:I am running a phenomX4 9950BE 2.6 and i had stock cooling for the longest time which sucked... my idle temps were 52 celcius with artic silver 5, as soon as i popped this bad boy in my temps went from 52c to 33c instantly this thing cools great.Cons: none
I'm running this Cooler: http://www.newegg.com/Product/Product.aspx?Item=N82E16835233012
At 3.6 running 4 instances of prime full load temps in a 70 degree ambient room are 42C.
Good Luck...
