On an AMD 6400+ (with ambient of 70F), I get idle temps of ~22C / Torture-Test temps of ~36. I''m using 2 AeroCool 50CFM fans on it. Since I have 2 of these, I will lapp one and compare the difference. With these kind of temps (using AS 5), I would highly suggest getting this for anyone looking for the sub-120mm air cooled solution. BTW I did not have to remove my MoBo for installing it onto the AM2 socket so total install took about 15min.
