Yeah, the Noctua is what? $80 or so? And the performance compared to a 212 with high flow fans is nearly the same if not a tad better? I don't see it being worth it. I paired a set of FM121 silverstones to my 212 and at 4.4Ghz I don't go over 63C at 1.216v on my 2600k and that's with IntelBurnTest which is known to get stock coolers on my processor to nearly throttling temperatures.
