Having received more than 100 awards and recommendations from international hardware websites and magazines, Noctuas flagship model NF-A12x25 has established itself as a true deluxe choice when it comes to premium-quality quiet 120mm fans. Various state-of-the-art technologies and a record tight tip clearance of only 0.5 mm, which is made possible by using the novel Sterrox® liquid-crystal polymer material, allow it to achieve superb results in all types of usage: Whether its in low-impedance, airflow-oriented applications such as case cooling, or high-impedance, pressure-demanding scenarios such as on heatsinks and watercooling radiators, the NF-A12x25 is a proven winner. The 4-pin LS-PWM version is a low-speed, PWM-enabled variant that is ideal for semi-passive setups or ultra-low-noise applications that require near-silent acoustics and PWM based speed control. Topped off with exceptional running smoothness, Noctuas reference-class SSO2 bearing, a rich bundle of accessories and 6-year manufacturers warranty, the NF-A12x25 is a premium-quality product through and through. Its superior efficiency, cutting-edge construction and pioneering materials make it an elite choice for the most discerning demands.

Ultra-quiet low-speed version with PWM
Producing only 12.1 dB(A) at its 1200rpm maximum speed and 7.6 dB(A) with the included Low-Noise-Adaptor, the LS-PWM version is ideal for serious silent-enthusiasts: An ultra-quiet low-speed fan that supports PWM control for advanced acoustic fine-tuning!
Sterrox liquid-crystal polymer compound
The NF-A12x25's impeller is made from Noctua's novel Sterrox liquid-crystal polymer compound that features extreme tensile strength, an exceptionally low thermal expansion coefficient and damping characteristics: ideal for reducing resonance and vibration phenomena in advanced fan-blade designs.
Ultra-tight tip clearance
The NF-A12x25 has a record tight tip clearance (distance between the blade tips and the inside of the frame) of only 0.5mm. This highly ambitious design sets a new benchmark for 120mm fans and helps the NF-A12x25 to work more efficiently against back pressure, such as on heatsinks or radiators, by reducing leak flows through the gap between impeller and frame.
Metal-reinforced motor hub
The centrepiece of the NF-A12x25's motor hub is made entirely from steel and the axle mount is reinforced with an additional brass structure. In combination, both measures ensure ultimate precision and increased stability in the critical hub area.
Scope of delivery
NA-RC8 Low-Noise Adaptor (L.N.A)
NA-YC1 4-pin PWM y-cable
NA-EC1 30cm extension cable
4x NA-AV2 anti-vibration mounts
NA-AVG1 anti-vibration gasket for water cooling radiators
Fan screws
Highly optimised P/Q curve for all applications
The NF-A12x25's sophisticated aerodynamic design allows for a pressure to airflow (P/Q) curve that is extremely strong in the critical mid-section. This means that the NF-A12x25 offers excellent performance in both static pressure demanding and airflow demanding applications.
