Hyper 212. Best bang for buck. Quiet-ish as long as you are not trying to cool a big overclock. Can be run at a fairly low speed if stock cpu clocks while still providing sufficient cooling. Thus not making a lot of noise. $30 ish dollars. And it fits in a mid tower case, as always double check dimensions before ordering.
*edit. Trying to get a good answer posted before Blackbird. Lol! As usual, a better reply, with links, and pertinent question(s) Good game to you sir.
