If you want something good for the money, Hyper 212 Evo forget about the V8, V6GT, or V10 options, those are pure crap and a waste of money.
If you want something better, Nocuta NH-D14 or H80i that's a closed loop liquid cooling system. So, would be best let us know your budget and the case that you have since the cooler size is an important factor when you look for a cooler.
I have a Cooler Master CM690 II advance http://www.coolermaster.com/product/Detail/case/mid-tower/cm-690-ii-advanced-usb3.html
as for budget I would say the least possible haha.
