Summary: I have an ASUS M2N-SLI motherboard with an AMD Athlon(tm) 64 X2 Dual Core Processor 5800+ 3.02 GHz running on it. I have a Ultra eTorque ULT33180 Mid-Tower ATX Case with red light tubes above and below just out of sight but throwing a red glow everywhere in the case. I wanted something to contrast the red and this fan looks like a blue jet engine intake smack in the middle of that red field. Perfect. Base of the fan mounted perfectly, no modding needed.
Summary: Works great on Aus M4A785-M MB. I've this cooler for about 18 months now and the cpu (Phenom 9750) never gets over 42C on max load, run in the low 30s most of the time. I spent more time opening the package and figures out what all the brackets were, than it took to mount. Very quiet in the low to mid range speeds. Now, I'll have to see if this cooler still workes as well on the Phenom II 965 I just ordered.
Summary: I purchased this to fix some overheating issues with my PC, and MAN what a difference. Took about 15 degrees Celsius off my temp. Can be turned down to be quiet, or turned up for maximum performance. It uses a 3-pin connector, as the 4th pin is used for fan speed control, which is done with the manual controls. The only issue I have is installation. I had to take my motherboard off, as it was not the cheap clip type that my Quad-Core came with.
