I would personally wait and buy the CM 212 Evo. Just because of it's price...the Noctua is a nice cooler, however that particular model is meant to be used for Low Profile situations (perhaps ITX builds and such) so it might not fair as much for cooling performance.
Of course, I may be wrong but so any input is appreciated.
The Hyper 212 Evo is an excellent & a very popular cooler. It has a terrific price to performance ratio.
