Thermaltake K450 (CL-P0075) AMD Athlon 64 Heatpipe Cooler

The first time I heard about the Thermaltake K450 heatsink was when I started my search for a CPU cooler for my Athlon 64 FX 55 in my SLI system. The problem I had was that the heatsink that was sent to me for my FX 55 was not meant for that CPU. I found this out by seeing my FX 55 temperatures soar to 70C when running Folding@Home. I knew this was way too high and headed to AMD's sight to find approved heatsinks. At that time, the only approved heatsink was the K450.

So after contacting Thermaltake, they sent me a K450, and my CPU temperatures went down to 55C when Folding! As you can see, this is a huge improvement and very good results considering I have 2 6800GT's in the machine running SLI. I liked the performance so much that I hooked up with CrazyPC to see if I could get another one for my FX 51 machine, which does server duty and Folding. So, today we are looking at the K450 replacing the heatsink that was on my FX 51 CPU.
