The NF-S12A case fan marks the third generation of Noctua's classic S12 series, which has received more than 250 awards and recommendations from the international trade press. Featuring an advanced blade geometry with anti-stall knobs and a new AAO (Advanced Acoustic Optimization) frame, the NF-S12A achieves up to 8% higher efficiency (airflow/noise ratio) compared to its renowned predecessor. The ULN version, with its super-low speed options (800/600 rpm), enables virtually silent operation, making it perfect for ultra-low-noise applications and particularly noise-sensitive users. Its outstanding quietness, the SSO2 reference-class bearing, and Noctua's proven premium quality make the NF-S12A an exquisite choice for noise-optimized case cooling.

Award-winning S12 design
The NF-S12A utilizes the third evolution of Noctua's classic straight blade design, which has earned the S12 series countless endorsements from hardware enthusiasts and journalists around the globe. Further optimized for even better airflow/noise efficiency, it makes the NF-S12A the ideal quiet case fan.

Anti-Stall Knobs
The NF-S12A's anti-stall knobs reduce vortex shedding in medium to high-drag situations, extending the stall margin. This makes the NF-S12A even more versatile than its predecessor and enables better results on heatsinks and radiators.

AAO frame system
Noctua's AAO (Advanced Acoustic Optimisation) frames feature integrated vibration dampers as well as a stepped inlet design and inner surface microstructures, enabling even better performance/noise efficiency.

Stepped Inlet Design
The stepped inlet design creates more turbulence in the intake. This facilitates the transition from laminar to turbulent flow, which adheres better to the frame (flow attachment), thus increasing the fan's suction capacity, especially in confined intake areas.

Inner Surface Microstructures
The inner surface microstructures of the frame create a boundary layer through which the fan blade tips move. This reduces flow separation from the suction side of the blade tips, resulting in a significant reduction in rotational noise and an increase in pressure and airflow efficiency.

Integrated anti-vibration pads
Made of extra-soft silicone, the anti-vibration pads reduce the transmission of even the smallest vibrations and are compatible with all standard screws and commercially available mounting systems or fan clamps used on CPU coolers.

Smooth Commutation Drive 2
The latest, enhanced version of Noctua's SCD drive system ensures exceptionally smooth operation by eliminating torque fluctuations and switching noise. This makes the NF-S12A remarkably quiet, even at close range.

2 speed options for maximum smoothness
The ULN (Ultra-Low-Noise) version offers 800rpm and 600rpm settings via the included adapter, making it perfect for silent enthusiasts who demand super-slow speeds and minimal noise.

Comprehensive connection options
While the short 20cm primary cable helps avoid cable clutter in typical applications, the included 30cm extension cable offers extra reach just in case. Both cables are fully sleeved, and a 3:4-pin adapter allows for direct connection to the power supply.

SSO2 warehouse
The NF-S12A features the further optimized second generation of Noctua's proven SSO bearing system. With SSO2, the rear magnet is positioned closer to the fan axis, providing even better stabilization, resulting in further improved precision and durability.

Metal bearing shell
To guarantee the greatest possible degree of manufacturing precision, minimal tolerances and excellent long-term stability, the NF-S12A uses a CNC-milled brass bearing shell.

6-year manufacturer's warranty
Noctua fans are known for their impeccable quality and outstanding durability. Like all Noctua fans, the NF-S12A boasts an MTBF rating of over 150,000 hours and comes with a full 6-year manufacturer's warranty.
