Summary: It was kind of a PITA to install, as I had to do some modifications to the motherboard itself to get the clips for the heatsink to secure everything properly. Still, the efforts were worth it. My 6 core processor was frying eggs in the high 60's C with the standard AMD fan/heatsink combo, and this heatsink brought things down into the mid 40's C. If I hadn't seen it with my own eyes, I might not have believed it.
Pros: 20C drop in CPU temp
Cons: Installation in ASUS M5A99 EVO required some fabrication skill. Instructions included are poor
Summary: CPU was overheating, causing motherboard alarm to sound. Replaced it with this one here and oh, it's nice and quiet. Easy installation, works well. Will be buying a second one for my boyfriend's computer - his cpu fan is so old and dusty it's begging to be put out of its misery.
Pros: Silent, keeps the processor cool, silent, keeps the processor cool, and did i say silent? Now I have to note that in my build it is a little louder than what it would be, but that is no fault of the cooler. The fault lies in my motherboard.
Summary: Needed to replace the noisy stock 70mm AMD cooler on my ASUS M4A88T-M Motherboard. Decided on this model based on its simple design, price and specs. Easy to install and computer is now very quiet and cool. I would purchase again.
