I'll just add that if noise level is your top priority, Thermaltake makes a couple of really quiet CPU coolers that have produced excellent results in my experience with them.

I have the second one in one of my machines, and have been pretty damn happy with it. For some reason, they list it as $59.99 on their site, but I have no idea why, since I was able to find mine for like $25.
But if 32dB doesn't bother you, the Hyper 212 has more cooling power ... although any of these ought to cool your system fine unless it's unusually prone to overheating for some other reason.
The Intel stock cooler looks like it tops out at around 37dB ... the Hyper 212 should be slightly quieter, while the first Thermaltake model goes down to 21dB and the second to 16dB.
