Correction I thought by the look of that it would be the best, but i did research on it and the best you can buy and it beats that zalman is the ThermalTake Big Typhoon.
i have that cooler now, no problems with it keep my skt 754 3200 running at 32c and a lower 40's at load. its pretty quiet too.but if you want the ultimate cooling get the typhoon, just make sure you can fit it in your case
