The Cooler Master 212 is the best cpu cooler at its price hands down. Hyper N520 is not that great, I am using it and I can only get my 1090t to 3.8Ghz cause temps are holding me back.
Agree on that, and the other guy also cited the Tt FRIO, which is freaking LOUD. The fan mount is pure plastic and does a lot of vibration noise
Plus, I happen to have the Hyper212 and it is hands down, as you said, the best performer at its price range.
For dual its price you can get a new Phanteks, a Noctua NH-D14 or the TPC.812 (vapor chamber cooler), or one of those single rad water coolers, BUT all of them only reduce 2 to 4 degrees celcius the already cold temps of the Hyper 212 evo.
