## Summary description

Noctua NF-S12A FLX is a 120 mm computer case fan in bronze colour, powered at 12 V and consuming 1.44 W. It provides airflow up to 107.5 m³/h with a speed range of 700–1200 RPM and noise levels from 7.4 dB (low) to 17.8 dB (high). Designed for case ventilation, it offers long MTBF (150,000 h) and moderate static pressure for steady cooling performance.

## Long description

The Noctua NF-S12A FLX is a 120 mm case fan engineered for efficient airflow and low noise. It belongs to the third generation of Noctua's S12 series, which has received wide recognition from the international press. The NF-S12A combines a refined blade geometry with Anti-Stall Knobs and an AAO (Advanced Acoustic Optimisation) frame to improve airflow-to-noise efficiency compared with its predecessor.
Advantages
The NF-S12A FLX delivers up to 8% better airflow/noise efficiency versus the previous S12 model, offering smooth operation thanks to the SSO2 bearing and high manufacturing quality. The FLX variant includes Low-Noise Adaptors that provide three speed settings (1200 / 900 / 700 RPM), enabling flexible tuning between maximum ventilation performance and near-silent operation. Compact dimensions (120 x 120 x 25 mm) and a standard 120 mm fan form factor ensure broad compatibility with PC cases.
Suitable for
 General case cooling in desktop PCs
 Systems where low noise is a priority (home or office PCs)
 Upgrading or replacing standard 120 mm fans

How to use
Install the NF-S12A FLX in a standard 120 mm fan mount inside your PC case, aligning the airflow direction as required for intake or exhaust. Use the supplied Low-Noise Adaptors to select the desired speed step (1200, 900 or 700 RPM) by connecting the adaptor between the fan connector and the motherboard or fan controller. Secure the fan with appropriate screws and connect its 3-pin or Molex power connector according to your system's headers or power supply.
Usage recommendations
For a balance of cooling and acoustic performance, use the 900 RPM adaptor for typical home and office systems. Choose 1200 RPM when higher airflow is required (e.g., densely packed components or higher ambient temperatures) and 700 RPM for near-silent operation. Periodically check and clean the fan blades and frame to maintain airflow and reduce noise from dust buildup.
