Description

NF-S12A ULN headerNF-S12A ULN 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 ULN version provides super-slow 800/600rpm speed settings for ultra-low-noise applications and highly noise sensitive users who demand near-silent operation. Its superb running smoothness, SSO2 bearing and Noctua’s trusted premium quality make it an elite choice for quiet case cooling

AAO frame

Noctuas AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads as well as Noctuas proprietary Stepped Inlet Design and Inner Surface Microstructures, both of which further refine the fans 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 Noctuas 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-RC12 Low-Noise Adaptor (L.N.A)
  • NA-AC1 3:4-pin adaptor cable
  • NA-EC1 30cm extension cable
  • 4x NA-AV1 anti-vibration mounts
  • Fan screws

Anti-Stall Knobs

The NF-S12As Anti-Stall Knobs reduce flow separation phenomena in medium to high impedance situations and thereby increase the fans 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.
