Having received more than 100 awards and recommendations from international hardware websites and magazines, Noctua’s 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 0.5mm, 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 it’s 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 chromax.black.swap edition combines the NF-A12x25’s signature quiet cooling performance with an attractive black design and a bundle of swappable red, white, blue, green, grey, yellow and black anti-vibration pads that allow the colour-customisation of the fan to match individual build colour schemes. For further customisation, a wide range of accessories such as coloured cables and anti-vibration mounts are available separately. Topped off with Noctua’s trusted premium-grade SSO2 bearing and more than 150,000 hours MTTF, the NF-A12x25 PWM chromax.black.swap is the perfect choice for all users who value individual, focused build aesthetics just as much as class-leading quality and performance.

Next-generation performance

Noctua’s 120mm fans such as the NF-F12 and NF-S12A are renowned as being among the best on the market and have received more than 400 awards and recommendations from the international press. With its further improved efficiency and novel, state-of-the-art engineering, the NF-A12x25 represents another step up in performance and manufacturing.

chromax.black.swap edition

Maximising colour choices, Noctua’s chromax.black.swap edition fans can be colour-customised using the included swappable anti-vibration pads as well as optional anti-vibration mounts and cables. This makes them ideal for enthusiasts looking for true premium-grade fans that can be colour-coordinated with popular build themes such as all black, black & white or black & red.

Sterrox liquid-crystal polymer compound

The NF-A12x25’s impeller is made from Noctua’s novel Sterrox liquid-crystal polymer (LCP) compound that features extreme tensile strength, an exceptionally low thermal expansion coefficient and damping characteristics that are 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.

Swappable anti-vibration pads in 7 colours

The NF-A12x25 PWM chromax.black.swap comes with 4 white, red, blue, green, grey, yellow and black NA-AVP1 anti-vibration pads. By combining the various colours with black or going all black using the supplied NA-AVG1 anti-vibration gasket, the fan can be coordinated with most popular build colour schemes out of the box. Additional NA-SAVP1 sets for outfitting both sides in one colour can be purchased separately.

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.
