Noctua NF-A14x25 G2 LS-PWM
The Noctua NF-A14x25 G2 LS-PWM PC fan builds on the award-winning NF-A14 fan, bringing an improved design for cooling computer builds. Its LS-PWM version is optimised for low-noise builds, including semi-passive systems, where the fan only starts up under a higher load. The body, made from Sterrox LCP liquid-crystal polymer composite, gives the construction high rigidity. This 140mm PC fan offers versatile use, whether for low-resistance case ventilation applications or for scenarios requiring high static pressure on CPU coolers and water-cooling radiators.
Key features of the Noctua NF-A14x25 G2 LS-PWM PC fan
- Fan body made of Sterrox LCP liquid-crystal polymer composite
- Powered by an etaPERF motor with Smooth Commutation Drive 2 technology
- Rotor axis is seated in a self-stabilising SSO2 oil-pressure bearing
- Low speeds of up to 800rpm keep builds quiet
- Advanced aerodynamic design with Flow Acceleration Channels
- Small gap between the blade and frame increases pressure
- Fan speed is automatically controlled by a 4-pin PWM connector
Advanced aerodynamics
The rotor uses blades with Progressive-Bend geometry and Flow Acceleration Channels to focus airflow and reduce turbulence. A small gap between the frame and the blade tips increases static pressure. The fan body is made of Sterrox LCP liquid-crystal polymer composite for high rigidity and stability.
Quiet fan motor
The fan is powered by an etaPERF motor with Smooth Commutation Drive 2 technology, which reduces torque pulses during phase switching. A self-stabilising SSO2 oil-pressure bearing ensures rotational stability, using an additional magnet for precise axis seating. The result is smooth fan operation and low power consumption. Connection via a 4-pin PWM connector provides automatic speed control by the motherboard.
Versatile use of the Noctua PC fan
Low speeds of up to 800rpm and an optimised design suit builds with an emphasis on quiet operation. It finds its use as a case fan, on CPU coolers, and on water-cooling radiators, where a pre-installed anti-vibration pad creates a tighter seal. Its features support the function of semi-passive systems, where it only starts up under higher load and maintains silence at idle.
