Go the extra $10-$15, and find a Noctua NH-D15.....(Check Noctua's website first for case compatibility, as the twin tower stack and fans sit fairly tall and require a certain case width. It fit my Corsair 100R case with about 1/4" to spare, but, there was not enough room for the 2nd fan attach to front of tower, so I used the 2nd fan as a case intake fan just a few inches away anyway)
