Noctua Nf-s12a Uln

The NF-S12A case fan marks the third generation of Noctua's classic S12 series, which has received over 250 awards and recommendations in the international trade press. With its advanced blade geometry featuring Anti-Stall Knobs and the new AAO frame (short for Advanced Acoustic Optimization), the NF-S12A achieves up to 8% higher efficiency (airflow/noise output) compared to its renowned predecessor. The ULN version offers super-slow speed options (800/600rpm) for near-silent operation, making it perfect for ultra-low noise applications and particularly noise-sensitive users. Its excellent smoothness, the SSO2 reference-class bearing, and Noctua's proven premium quality make the NF-S12A a distinguished choice for noise-optimized case cooling.

Award-winning S12 design: The NF-S12A utilizes the third evolutionary stage of Noctua's classic Straight Blade design, which has garnered countless recommendations from hardware enthusiasts and journalists worldwide for the S12 series. Further optimized for even better airflow/noise efficiency, the NF-S12A is the ideal quiet case fan.

Anti-Stall Knobs: The NF-S12A's knobs reduce vortex shedding phenomena in medium to high flow resistance situations, thereby extending the so-called stall margin (flow separation threshold). This makes the NF-S12A even more versatile than its predecessor, allowing for better performance on heatsinks and radiators.

AAO frame system: Noctua's AAO (Advanced Acoustic Optimization) frames feature integrated vibration dampers, a stepped inlet area (Stepped Inlet Design), and inner surface microstructures that enable even better performance/noise efficiency.

Stepped Inlet Design: The stepped inlet area of the Stepped Inlet Design creates more turbulence in the airflow.
