The question that should be asked is what are your plans for the CPU cooler... are you looking just for better cooling, reduced noise, or do you want to overclock the hell out of the CPU?
If you're simply looking for better cooling, or just mild overclocking without upping voltages than pretty much any aftermarket cooler will work well. It's more about reducing the noise and price than cooling.
If overclocking is your goal then you need to look at coolers like the T.R.U.E., CoolerMaster V8 and such. I've never used the TRUE, but I was a beta tester for the CM V8 and can vouch it works well and at full speed is very quiet while it cooled better than the Zalman I have. But if you're just looking for something that's quiet, or a little better cooling then both of those coolers are overkill.
He wanted one with the retention clip fitting. The Coolermaster V8 doesn't have that, wheras the Zalmans do.
