yea, the 212 EVO is a nice choice,
The next step up from that cooler (staying smallish in size and price) = Thermolab's Trinity
This link gives a nice idea of what to expect from most current coolers - fans on HighFrostyTech CPU Cooler Comparison
I would add that each review could be "slightly" different - luck of the draw, better seated or better base for the test that day etc
and also if you want to try for the limits of overclocking with higher than normal overclocking volts - then choose a Good cooler...
