The Noctua is the better performer (and priced accordingly). However, for light OC, and gaming the Hyper 212 EVO will work very well. (I have the Hyper 212 EVO on my OCed i7 3770K running at 4.6 GHz and we game at high settings. No issues).
Only use one fan on the EVO second one will offer no boost in performance.
No contest in the cooling dept. D14 wins.
way u thing only 1 fan will be better then 2?
