Silent Cpu Cooler

Hi, I'm looking to make my pc as silent as possible. I have a the Fractal Design R4 to start off, but what I'm looking for is a silent cpu cooler, to cool my 3570k. I've been looking into the H100i, but I've heard it can be pretty loud, any suggestions would be much appreciated, thanks! 

Well any large air cooler will work, or if you want you could get a custom loop (its what im doing) with some quiet fans if it doesent alreadu have some.

if you don't plan on overclocking, get the Cooler Master Gemin II. It's a very quiet cooler.

The Phanteks PH-TC14PE! Just make sure your RAM is under 50mm, otherwise it won't fit.
