Hi, I haven't really changed the insides of my computer for quite a few years now and frankly am just waiting for a dramatic enough increase in price-to-performance for CPU to justify ditching my i7-4770 and 16 gigs of DDR3 (I know, it's archaic, but it gets the job done).
In the meantime however, I've gotten increasingly annoyed by the loud sound of my computer's fans, and I've been wondering what the best modern fans are for performance and quietness. My config is two 120mm fans on the front, one 120mm on the heat sink, and one 120mm on the back.
Right now I'm looking a lot at the Noctua NF-F12, but is there anything better I can get today? My budget at most is about $25 per fan.
