## Summary description

Noctua NF-A12x25 ULN is a 120 mm computer case fan designed for low-noise operation. It runs at up to 1200 RPM on 12 V, consuming 0.6 W (0.05 A) and delivering 55.7 m³/h airflow with a static pressure of 0.82 mmH2O. Constructed with LCP blades and SSO bearing, it offers long life (MTTF 150,000 h). Includes 3‑pin connector, mounting screws and cable.

## Long description

The Noctua NF-A12x25 ULN is a 120 mm computer fan engineered for exceptionally quiet and efficient cooling. It combines advanced aerodynamic features—such as the AAO (Advanced Acoustic Optimisation) frame and Flow Acceleration Channels—with a tight 0.5 mm blade tip clearance enabled by the Sterrox® LCP material and a metal-reinforced motor hub. The ULN (Ultra-Low-Noise) variant provides reduced speed settings for near-silent operation while remaining suitable for both airflow-oriented case cooling and pressure-demanding applications like heatsinks and watercooling radiators.
Advantages
The fan offers very low operational noise through slow-speed settings and acoustic optimisation, high precision and durability thanks to a metal-reinforced motor axis and Sterrox® LCP blades, and smooth, long-lasting operation using Noctua’s SSO2 bearing. Its construction yields a balance of airflow and static pressure that makes it effective across a wide range of cooling scenarios. The product includes a comprehensive accessory bundle and is backed by a 6-year manufacturer’s warranty.
Suitable for
Quiet case cooling where low noise is a priority
Heatsinks and CPU coolers that require moderate static pressure
Watercooling radiators needing efficient airflow at low noise levels
Silent or noise-sensitive workstation and media PC builds
Key specifications
Model: Noctua NF-A12x25 ULN (MPN: NF-A12x25 ULN, EAN: 9010018100372)
Fan diameter: 120 mm
Speed setting: ULN (max ~1200 rpm) with lower fixed-step speeds (e.g., 1200/900 rpm)
Airflow: 55.7 m³/h (manufacturer data)
Max static pressure: 0.82 mmH2O (manufacturer data)
Bearing: SSO2 (self-stabilising oil-pressure bearing)
Colour: beige / brown
How to use
Mount the fan using the supplied anti-vibration mounts or screws so that airflow orientation matches your cooling needs (intake or exhaust). Connect the 3-pin power cable to a compatible fan header on the motherboard or controller and set the desired low-noise speed profile in BIOS or via a fan controller. When used on heatsinks or radiators, ensure proper spacing and unobstructed airflow to maintain static pressure performance.
Usage recommendations
For the quietest operation, use the ULN speed setting or a fan curve that keeps RPMs near the 900–1200 rpm range; clean dust filters and radiators regularly to preserve airflow and static pressure efficiency.
