It runs at 12 V with two speed modes (600–800 RPM), delivers up to 74.3 m³/h airflow and up to 0.62 mmH2O static pressure while consuming 0.72 W. Noise ranges from 6.7 to 8.6 dB. Features include speed detection and long MTBF (150,000 h). Not for damp or wet areas.

## Long description

The Noctua NF-S12A ULN is a 120 mm case fan engineered for ultra-low-noise operation in desktop PCs. It belongs to the third generation of Noctua's S12 series, offering improved airflow-to-noise efficiency compared with its predecessor. The ULN (Ultra-Low-Noise) variant provides very slow rotational speeds for near-silent performance while still delivering effective case airflow and reliable long-term operation.
Advantages
The NF-S12A ULN features a refined blade design with Anti-Stall Knobs and an Advanced Acoustic Optimisation (AAO) frame to increase aerodynamic efficiency and reduce noise. It runs at 800/600 RPM speed settings for minimal acoustic output, uses a SSO2 bearing for smooth, durable operation, and comes from Noctua's established quality standards for reliable cooling components.
Suitable for
Silent or near-silent PC builds
Home theatre PCs and media centers where low noise is important
Workstations in noise-sensitive environments
General case cooling in desktop systems
Key specifications

How to use
Install the NF-S12A ULN into a standard 120 mm fan mount in your PC case, aligning the airflow direction arrow on the frame with the desired intake or exhaust orientation. Connect the fan to a 3-pin or compatible motherboard header or fan controller supporting 12 V operation and select the ULN 600/800 RPM setting if available on the controller. Ensure screws or anti-vibration mounts are used to secure the fan and reduce mechanical noise transfer.
Usage recommendations
The fan is designed for applications where minimal noise is the priority. For improved cooling under higher load, consider using higher-speed variants of the S12A series or combining the ULN fan with additional intake/exhaust fans while monitoring case temperatures.
