Well, they're comparable in heat dissipation, but the SLK-900a is the only one with mounting clips. The 947u has to be mounted thru the motherboard, so if yours doesn't have the 4 mounting holes near the cpu, you'll have to get the 900a. Oh, and it's good enough to OC a Barton to 2.5ghz, and keep it around the low-40's at idle, I hear.Originally posted by: mrchan
which one is better? how much better is it compared to my FOP38?
man, $40 for a heatsink is a lot, heh. my Duron 1800 -> XP2200+ only cost $25.
