Thermalright SLK-900A that's what I got and works great. I also have that Jet7 but I used the heatsink for my secondary computer and used the blower fan in my case mod project
so the actual blower is behind my motherboard CPU socket blowing in
Anywho that Thermalright SLK-900A works great and I think they got now SLK-948U for socket A that has heatpipe technology which is supposed to work really good. Both of those can take up to 92x38 fan which is a 92mm high performance fan, a normal 92mm fan is 92x25, 80mm's are the same way, 25 is normal widthe and 38 is high performance....
It's a nice solid copper heatsink and works good..
Also appearantly coolermaster released a new heatsink and fan combo called the HyperSeries or something along those lines. Ag3 claims this has given him yet another decrease in temperatures from his already adequately cooled system
