Don't tell me the NF-F12 make weird noise in pull because I know
Edit: I go for PWM version of both.
F12's, eLoops are over-rated fans right out the gate.
They look cool, but their big fancy blade design doesn't do much for them.
There's a reason that Noctua's best line up of a fans (F12, A14, A15, P12, & S12A) all use very basic fan blade designs. The "vortex control notches" they put into the blades alter the tone & drop airflow / pressure slightly but considering they're a silence oriented company and it's less than 5% drop, I don't find it to be a terrible decision.
