Thermalright SLK-800 Socket-A @ Viper Lair
 

"For the most part, air cooling performance between the SLK-800 and the MCX462+ is a draw. One advantage the SLK-800 has is that it's probably more compatible than the MCX462+, since many of the newer AMD motherboards don't have the four mounting holes. It's flexible, accomadating three sizes of fans, though I'd imagine most of you will stick with the 80mm ones, and possibly the 70mm ones."
