What tetris said. It cools just as good if not better than the H70 and is far quieter. I have the Noctua set on a user fan profile and I still don't hear it at max RPM on both fans.
The only thing I hear from my case, oddly enough, is my graphics card. I don't hear the case fans or the NH-D14. I use a HAF 922 with the fans the case came with, but I'm looking to change at least 2 of them out for 3 more Noctua fans.
