Yeah, I stand along side rudster816 when I say the Cooling Freezer is the cheapest, yet most effective solution apart from water cooling, or a very very loud fan.
The Arctic Cooling Freezer is whisper quiet, and can't be heard above everything else most of the time.
I have the 64 edition for my AMD, and its never been cooler.
Well worth the small price
Just make sure your case can support it. Its pretty hefty.
