Noctua NF S12A ULN 120mm Fan

Noctua NF-S12A ULN: Ultra-Low-Noise 120mm Fan

The Noctua NF-S12A ULN redefines silent cooling with its 900 RPM fixed speed, delivering 55.5 CFM (94.2 m³/h) airflow at just 12.6 dB(A). Featuring Noctua’s AAO frame and 7-blade design optimized for unrestricted airflow, this fan operates below the threshold of human hearing while maintaining exceptional performance. Furthermore, its SSO2 bearing ensures >150,000 hours of maintenance-free operation, making it ideal for silent PCs and HTPCs.

Whisper-Quiet Engineering:

With an aerodynamic blade geometry and integrated anti-vibration pads, the NF-S12A ULN achieves near-silent operation without compromising airflow. The ULN (Ultra-Low-Noise) version runs at fixed 900 RPM, eliminating PWM motor noise while providing sufficient cooling for most applications. Moreover, the staggered blade tips and inflow acceleration channels minimize turbulence for efficient airflow with minimal acoustic signature.
