Silent and blowing
Noctua's reputation is well established. It may be more expensive, but it's also powerful and very quiet. I bought it to complete the ventilation setup of a Fractal Design North XL, and I have to turn down the fans on the tower by half to hear the additional Noctua fans and the processor fan. And in fact, I can afford to turn down the tower fans quite a bit (3 fans, no less), since these three + this Noctua at the inlet and two of these Noctuas at the outlet still allow for positive pressure and effective cooling.
