I currently run 6 * i7s in my little render farm, and when upgrading one machine to 4770K recently I decided to try a single rad Coolermaster Seidon 120V instead of the stock Intel cooler just as an experiment. Since I already had another 4770K (same mobo, ram etc) in my setup I was able to do a side by side test of water vs stock Intel cooler.
This screenshot was taken using remote desktop + Aida64, and shows the 2 machines rendering different frames of the same Cinema 4D project. The water cooler system is about 15C below the stock cooler.

not bad for about £30
Cooler Master: Seidon 120V
