I recommend this sink all in one (fan and sink into a block), I went from a jet prior to a very silent stealth fighter even at full load. Despite this impressive size, it fits perfectly into either a tower ATX, for quick installation for already fit for my amd socket, if necessary you just change the motherboard support provided in the box. Nivo performance I won 4-5 ° from the original one to rest and support about 10-12 ° at full load. I'm about 45 ° on a phenom 9550 quad-core at full load.
