Greater than one weekThese fans are so quiet that now my CPU water pump annoys tf out of me. Seriously, I never knew it was this loud until it was the only noise my PC made.

> 3 dayI bought this as a second pull CPU fan. I quickly mounted it to my CPU cooler, resulting in one push and one pull fan to increase airflow across the cooler radiator.

09-06-2025LOVE these Noctua fans! I replaced all my case fans and my CPU fan with these redux models and could NOT be more satisfied!! They were the perfect fit for silencing my sound dampening case to ridiculous levels. I even like the colors better than the standard Noctua line of cream and maroon. These are a great deal and a win-win for anyone that wants Noctua silence and quality without the high price point of standard Noctua lines of products!

09-06-2025With regard to the Noctua NF-S12B redux-1200 PWM fan: They are relatively inexpensive but (to me) are much noisier than the spec indicates. Late at night or when there is little ambient noise, they can be easily heard when spinning up to handle a temp increase (via PWM). The elevated sound is a smooth whoosh -- not tremendously bothersome but still very noticeable.

> 3 dayThis fan lives up to the Noctua reputation for quiet fans providing good airflow and static pressure. It should serve well as a radiator fan or general purpose case fan.

> 3 dayI put 7 of them in my PC and it exceeded my expectations. Great high-performance fans for the price. Just know the difference between airflow and static pressure and you wont go wrong with Noctua fans.

Designed for efficient case ventilationTypical PC case ventilation applications require high airflow but only medium static pressure. The NF-S12B has been specifically designed for high airflow efficiency and low noise in order to provide best results in these so called low impedance applications . |
SSO-BearingCombining the proven concept of hydrodynamic bearing with an additional magnet that supports the self-stabilisation of the rotor axis, Noctua"s time-tested technology has become synonymous with supremely quiet operation and exceptional long-term stability. |
Bevelled Blade TipsReducing critical rotor stator interaction, Bevelled Blade Tips permit to combine extended leading edges and a higher blade surface area with quieter operation and thus form a cornerstone of the fan"s outstanding efficiency. |
Colour-customisable with NA-SAVP1 anti-vibration padsThe fan’s frame can be outfitted with Noctua’s chromax line NA-SAVP1 anti-vibration pads. Available in black, red, blue, white, green and yellow, these pads not only damp minute vibrations but also allow the fan to be colour-customised in order to coordinate it with popular build colour schemes! |
