Noctua NF-A14x25r G2 PWM chromax.black

State-of-the-art quiet cooling performance for CPU coolers in a sleek all-black design: The chromax.black version of the award-winning NF-A14x25r G2 round-frame 140mm fan.

Succeeding the iconic NF-A15, the NF-A14x25r G2 has quickly established itself as a new benchmark for premium quality quiet round-frame 140x25mm fans.

Its advanced aerodynamic engineering featuring a novel Progressive Bend impeller design with 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.

At the same time, its etaPERF motor with SupraTorque can leverage extra torque headroom when required, which makes the NF-A14x25r G2 an ideal upgrade for NH-D15, NH-D15S and NH-U14S heatsinks.

The chromax.black edition combines the NF-A14x25r G2’s Sterrox liquid-crystal polymer impeller, comprehensive feature set and breakthrough quiet cooling proficiency with an attractive black design.

Topped off with Noctua’s trusted premium-grade SSO2 bearing, more than 150,000 hours MTTF and a 6-year manufacturer’s warranty, the NF-A14x25r 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.

Award-winning NF-A14x25r G2 design

Providing a significant performance boost over the renowned NF-A15, the NF-A14x25r 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 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.

Centrifugal Turbulator hub

Acting as a turbulator, the new Centrifugal Turbulator hub design improves flow attachment in the hub region. At the same time, its centrifugal driving motion pushes air outwards from the hub area where efficiency is low due to the slow rotational speed towards the outer, high-efficiency zones of the blades, thereby increasing overall efficiency by optimising fluid distribution across the impeller area.
