I installed one of these on Sunday:
I had it sitting around for about two weeks, since I never got the two 120mm fans. Well I got the fans, two 120mm Coolermasters, 1200 RPM, Blue LED, 22 Decibals… I also added two of these same fans to my case.
This thing kicks ass!
Using the stock cooling, my Athlon 64 X2 6000+ was running at about 45 degrees idle, and around 65 - 70 full load. With the new cooler + the 120mm fans, my CPU is running at 33 degrees idle, and 55 degrees full load. My comp is really quite now, to!
