## Summary description

Noctua NF-A12x25 is a 120 mm computer case fan with 25 mm depth, liquid crystal polymer blades and SSO bearing. It operates at 12 V, consumes 0.6 W (0.05 A) and offers 450–1200 RPM with airflow up to 55.7 m³/h and maximum static pressure 0.82 mmH2O. Comes in brown/beige, 4‑pin PWM connector, 0.5 m cable and mounting screws included.

## Long description

The Noctua NF-A12x25 LS-PWM is a premium 120mm computer fan designed for quiet, efficient cooling in cases, heatsinks and watercooling radiators. It operates between 450 and 1200 RPM, provides up to 55.7 m³/h airflow and features a self-stabilising oil-pressure (SSO2) bearing, Sterrox® liquid-crystal polymer impeller and a metal-reinforced motor hub for improved durability and precision. The LS-PWM low-speed PWM variant is suited for semi-passive systems and ultra-low-noise setups, and the fan includes a silicone gasket for radiator mounting and anti-vibration pads for reduced transmission of vibrations.
Advantages
The NF-A12x25 combines a highly optimised pressure/airflow curve with state-of-the-art aerodynamic features such as Flow Acceleration Channels, Stepped Inlet Design and Inner Surface Microstructures to deliver efficient cooling in both high-impedance and airflow-oriented applications. Its ultra-tight 0.5 mm tip clearance, Sterrox® LCP impeller, CNC-milled brass bearing shell and metal-reinforced hub increase efficiency, stability and long-term reliability. The LS-PWM version offers very low acoustic levels (12.1 dB(A) at 1200 RPM, lower with the Low-Noise Adaptor), PWM speed control including stop-at-0% for semi-passive operation, and a custom PWM IC with Smooth Commutation Drive to reduce switching noise.
Suitable for
Case cooling in compact or airflow-oriented builds
Heatsinks and CPU coolers requiring static pressure
Watercooling radiators (with included gasket; optional NA-FMA1 adaptor for 140 mm frames)

How to use
Install the fan using the standard screw mounting or the included anti-vibration pads, aligning the airflow direction as required for case ventilation, heatsink or radiator placement. For radiator installations, use the supplied silicone gasket to improve sealing and reduce air loss. Connect the 4-pin PWM cable to a compatible motherboard or fan controller to enable automatic speed regulation and the stop-at-0% function for semi-passive operation. If mounting to a 140 mm frame, use the optional NA-FMA1 adaptor.
Usage recommendations
For lowest noise in idle or light-load scenarios, enable PWM control and use the Low-Noise Adaptor; for radiator or heatsink applications that demand higher static pressure, maintain proper tip clearance and use the silicone gasket to reduce air leakage and vibration transmission.
