They have the same MTBF, although I do believe Noctua has 1 year better warranty (I can't recall off the top of my head).
That's not with any proper testing mind you, just an average over the few days I ran each on my CPU cooler. The Scythe fan may be louder, but it's not noticeably louder when it's inside your case and you're sitting at least 1m away from it (I can't hear either fan to be quite honest, and I turned my GPU fan down to 10% to check it out).
I love both fans - they're excellent performers, and I'm looking forward to doing some proper tests once I pick up a few more fans for a 120mm fan shootout. But initial ghetto-testing reveals at least to me that the S-Flex at 1600RPM cools a CPU better than the Noctua NF-P12.
Yep, I concur... I've owned many 120mm fans(Sycthe, CM, Sanyo denki, Yate Loon, Noctua, thermaltake, Mad dog <- Rofl, ect ect). Sanyo Denki aside(they're in a league of their own), the Scythe S-Flex are tops in my book and they actually perform similar to their rated specs, unlike some other manufacturers *cough* silenx *cough*.
5 SFF21Ds for $55
is the cheapest I've ever seen these fans...
The same shop has the most monstrous fan I've ever laid eyes upon:
