Noctua Fan NF-S12A ULN Knobs Blade Tips 2-Speed SSO2 Bearing 12cm Retail

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 Optimization) 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.

Award-winning S12 design

The NF-S12A features the third evolution of Noctua’s classic Straight Blade Design that has earned its S12 series countless recommendations from hardware journalists and enthusiasts around the world. Further optimized for even better airflow/noise efficiency, it makes the NF-S12A an ideal quiet case fan.

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

A4O Frame

Noctua’s A4O (Advanced Acoustic Optimization) 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.
