Get the FOP32. Apparently it's a tad loud, but certaintly not in comparison with the FOP38. It cools very well, and is only $20 at
www.2cooltek.com, you might want to get a small packet of thermal compound, too.
Heh, in fact, I'm just about to get an MSI K7T Pro2A, too, for my Duron 600 (that will, according to my seller, OC to 1 Ghz) and am going to get the FOP32 (I'm going to get a shim, too....check another thread, a guy was selling them for $6 + shipping.) I heard the FOP32 was troublesome to install (at least on a KT7 board)...hope i don't screw something up. After I install the mobo in the case, I should apply thermal compound to the "AMDDuron" plateau-cube thing in the middle of the cpu, right? Then put it in the socket, pull the lever down, place the shim on, then put the FOP32 on, right?
