State-of-the-art quiet cooling performance for PC cases and water cooling radiators in a sleek all-black design: The chromax.black version of the award-winning NF-A14x25 G2 140mm fan.

Succeeding the iconic NF-A14, the NF-A14x25 G2 has quickly established itself as a new benchmark for premium quality quiet 140x25mm fans.

Its advanced aerodynamic engineering featuring a novel Progressive Bend impeller design with a Centrifugal Turbulator hub, winglets, and a record tight tip clearance of only 0.7mm enables the G2 model to provide a significant boost in performance-to-noise efficiency over its renowned predecessor: Whether it’s in low-impedance, airflow-oriented applications such as case cooling, or high-impedance, pressure-demanding scenarios such as on water cooling radiators, where its etaPERF motor with SupraTorque allows leveraging extra torque headroom, the NF-A14x25 G2 is a proven winner.

The chromax.black edition combines the NF-A14x25 G2’s Sterrox liquid-crystal polymer impeller, comprehensive feature set and breakthrough quiet cooling proficiency with an attractive black design that can be customised with coloured anti-vibration pads that are available separately.

Topped off with Noctua’s trusted premium-grade SSO2 bearing, an MTTF of more than 150,000 hours and a 6-year manufacturer’s warranty, the NF-A14x25 G2 PWM chromax.black is the perfect choice for users who are looking for cutting-edge quality, quietness and performance in an all-black style.

“In terms of performance, the Noctua fans have a marginal lead of 0.9°C over be quiet! fans but win here comes from the fact that Noctua fans spin at around 1500 RPM to deliver this result, compared to 2000 RPM on be quiet! fans for the result. ”

Key features

Award-winning NF-A14x25 G2 design

Providing a significant performance boost over the renowned first-generation NF-A14, the NF-A14x25 G2 has become a new favourite among quiet cooling enthusiasts. With rave reviews and dozens of awards from hardware media around the world, the G2 model is a proven premium choice for the highest demands.

chromax.black edition

From the impeller and fan frame to the anti-vibration pads, anti-vibration gasket, anti-vibration mounts, screws and cables, the chromax.black edition is black from head to toe, making it easy to integrate into all-black PC builds and various other environments.

SupraTorque™

Most fans become slightly slower when working against back pressure such as on heatsinks and radiators, which results in reduced performance. Enabled by the new NA-FD6 driver IC, Noctua’s SupraTorque™ technology allows the fan to leverage additional torque headroom when required in order to keep its RPM speed at the desired level no matter the airflow resistance, ensuring consistent performance even in the most demanding conditions.

Ultra-tight tip clearance

The NF-A14x25 G2 has a record tight tip clearance (distance between the blade tips and the inside of the frame) of only 0.7mm. This highly ambitious design sets a new benchmark for 140mm fans and helps the NF-A14x25 G2 to work more efficiently against back pressure, such as on heatsinks or radiators, by reducing leak flows through the gap between impeller and frame.
