## Summary description

The Noctua NF A12x25 FLX is a 12 cm computer case fan featuring a maximum speed of 2000 RPM, airflow of 102.1 m³/h, and a maximum air pressure of 2.34 mmH2O. It utilizes a self-stabilizing oil-pressure bearing for quiet operation and durability. With three speed settings, this fan is designed for optimal cooling performance while maintaining low noise levels.

## Long description

The Noctua NF-A12x25 FLX is a 120 mm case fan that combines advanced aerodynamic engineering, a Sterrox® liquid-crystal polymer impeller and a metal-reinforced motor hub to deliver efficient and quiet cooling. Designed as a versatile all-rounder, it performs well in both low-impedance airflow applications such as general case ventilation and in high-impedance, pressure-demanding scenarios like heatsinks and watercooling radiators. The FLX version includes Low-Noise Adaptors to set three speed levels (2000 / 1700 / 1350 RPM) and comes with comprehensive accessories and a 6-year manufacturer’s warranty.
Advantages
The NF-A12x25 FLX features an ultra-tight 0.5 mm tip clearance, Flow Acceleration Channels, an AAO frame with Stepped Inlet Design and Inner Surface Microstructures, and integrated anti-vibration pads to improve efficiency and reduce noise under back pressure. Its Sterrox® LCP impeller and metal-reinforced motor hub increase structural precision and reduce resonance, while the SSO2 bearing, Smooth Commutation Drive 2 and CNC-milled brass bearing shell ensure durable, smooth operation. The package includes extension and adapter cables plus an anti-vibration gasket for radiator mounting.
Suitable for
Case cooling and general chassis airflow
Heatsinks and air coolers that require static pressure
Watercooling radiators (with optional NA-FMA1 adaptor for 140 mm frames)
Quiet or high-performance PC builds with adjustable speed settings

How to use
Install the NF-A12x25 FLX using standard 120 mm mounting holes and screws or use the included anti-vibration gasket when mounting on watercooling radiators. Connect the 3-pin connector to a motherboard fan header or to the power supply using the supplied 3:4 pin adapter. Select the desired speed by using the supplied Low-Noise or Ultra-Low-Noise Adaptors to set 2000, 1700 or 1350 RPM depending on whether you prioritise cooling performance or lower noise.
Usage recommendations
For optimal acoustic performance on heatsinks and radiators, ensure minimal gap between fan and radiator surface and use the supplied silicone gasket when a tighter seal is possible. Allow adequate airflow paths inside the case and avoid obstructing the intake or exhaust to preserve the fan’s efficiency and low-noise characteristics.
