The FOP32-1 works just fine - I've got 2 on my 2 x PIII 750Es and with good thermal paste they run @ 28C idle/36C flat out. If I run them @ 997MHz this changes to 32C/42C, which I think is pretty damn good. Sure, the Alphas are good coolers and have a higher bragging factor, but personally I think it's just plain stupid to pay through the nose for (maybe) one or two degrees less. But hey, that's just me....
