Also, I am willing to pay more for fans if they are very reliable with a good warranty. I saw the Noctua fans have a 6-year warranty, at $25 each - for example.
I have both of those Noctuas and the 140mm is surprisingly loud..er than I would expect from Noctua. My T.B. Silence 140 is much quieter, though a different sort of fan. barelyhear it 2 feet away. As a silent computing nut, I've become disillusioned with Noctuas recently. I think one of the best pricey options is a fan controller and low-medium speed Scythe Slipstreams, but theyre 12-18 bucks a pop; good fans though and they take pretty low volt to to startup so are fairly flexible. Cheaper option is Enermax, my budget fave. I hear good things about Gelid as well. Just make sure you have enough well placed fans to compensate for the lower cfm silence brings, and you should do fine for cooling.
Cougar is a sort of newcomer in quiet fans and I've heard good things but dont know much about them.
