The newer Hyper 212 being the EVO apprently are not quite as good as the Hyper 212+ fan bracket version in regards to raw performance, however, the EVO I believe has its heatpipes set a touch wider so it is better for a larger cpu example a Sandy-E chip.
Hyper 212+ fan bracket version (which is apprently what they call them now) is what I would get, very excellent cooler, can arrange it in different orientations, and at least with the one that uses the brackets vs the wire clips, its nice because you can slide the fan up/down the heatsink to get better compatibility in regards to using taller/shorter ram or getting as much air as possible over the motherboard.
For mine, I paid $24 for the 212+ bracket version and another $8 for an extra fan and I added MX4 paste to it as well, very impressed with what it can do :)
