Quiet but wimpy 04/30/2014
This review is from: Noctua Anti-Stall Knobs Design,SSO2 Bearing 120mm, PWM Case Cooling Fan NF-S12A
Some of the quietest fans I own, especially at low speeds. Absolutely no low speed bearing noise like most other fans.
* Very little flow at low speeds
* Dismal flow when the fan is mounted behind an intake filter or in front of my case's outtake mesh.
Swapped out to a different fan that had a more full fan blade design and it seemed to push more air.
