    If a mouse were to fart in the Arctic I think Id stand a better chance of hearing it over the fan 2ft away from me.

    Wie immer in gewohnter Qualität, sehr langlebig, laufruhig und macht was er soll.

    Etwas schwierige Montage der noise adapter, aber dass ist vom gehäuse abhängig. Die Qualität der lüfter ist beeindruckend. Durch etwas andere Anordnung ist es im cooltek g3 gehäuse wesentlich kühler. Die lüfter laufen deutlich leiser und bauen wesentlich mehr Druck auf. Die lüfter sind ihr Geld wert.

    Been using this brand for the last 8 years, no issues. I was expecting 19db rated to be silent, but a low wind can be heard.

    Gran ventilador de 120mm, buen flujo de aire a la vez que proporciona poco ruido. Desde que conoci noctua solo compro esta marca, aunque es un poco mas cara que la competencia añorta calidad.

    Ottima ventola dal punto di vista qualitativo, ma visto che mi interessava che fosse più silenziosa lho restituita, in quanto trovo che le arctic costando meno della metà siano ugualmente silenziose.

    As always, great Noctua quality. Their products are a bit expensive, but very much worth it! Really the only downside is the colours, if you have a themed PC build. My case doenst have a window, so I dont really care about the colour scheme.

NF-S12A PWM HeaderNF-S12A PWM Header

The NF-S12A marks the third generation of Noctua’s signature S12 series quiet case fans, which have received more than 250 awards and recommendations from the international press. Featuring a further refined blade design with Anti-Stall Knobs that works in tandem with the new AAO (Advanced Acoustic Optimisation) frame, the NF-S12A improves the airflow/noise efficiency of its renowned predecessor by up to 8%. The PWM version sports Noctua’s custom designed NE-FD1 IC for fully automatic speed control via 4-pin fan headers and comes with a Low-Noise-Adaptor to reduce the maximum speed during PWM control from 1200 to 900rpm. Its superb running smoothness, SSO2 bearing and Noctua’s trusted premium quality make it an elite choice for quiet case cooling

AAO frame

Noctua"s AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads as well as Noctua"s proprietary Stepped Inlet Design and Inner Surface Microstructures, both of which further refine the fan"s performance/noise efficiency.

Integrated anti-vibration pads

Integrated anti-vibration pads made from extra-soft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard screws and other mounting systems.

SSO2 bearing

The NF-S12A features the further optimised second generation of Noctua"s renowned, time-tested SSO bearing. With SSO2, the rear magnet is placed closer to the axis to provide even better stabilisation, precision and durability.

Inner Surface Microstructures

With the tips of the fan blades ploughing through the boundary layer created by the Inner Surface Microstructures, flow separation from the suction side of the blades is significantly suppressed, which results in reduced blade passing noise and improved airflow and pressure efficiency.

Scope of delivery

  • NA-RC7 Low-Noise Adaptor (L.N.A)
  • NA-YC1 4-pin PWM y-cable
  • NA-EC1 30cm extension cable
  • 4x NA-AV1 anti-vibration mounts
  • Fan screws

Anti-Stall Knobs

The NF-S12A"s Anti-Stall Knobs reduce flow separation phenomena in medium to high impedance situations and thereby increase the fan"s stall margin. This means that the NF-S12A is even more versatile than its renowned predecessor and can achieve better performance on heatsinks and radiators.
