Noctua NF-A14x25 G2 PWM Sx2-PP Chromax Black Fan - 140mm

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 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.

The Sx2-PP set contains two fans that are slightly offset in speed (+/- ~25rpm) in order to avoid undesirable harmonic phenomena such as beat frequencies, which can be heard as intermittent vibrations or periodic humming due to interference. This makes it ideal for both push-pull applications and situations where two or more fans are running side by side such as in typical case fan configurations as well as on 280 or 420mm water cooling radiators.

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-A14x25 G2 PWM Sx2-PP chromax.black is the perfect choice for users who are looking for a dual 140mm fan set that combines cutting-edge quality, quietness and performance in an all-black style.

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.

Dual fan set for push-pull and side-by-side usage
Bundling two NF-A14x25 G2 PWM fans that are speed-offset by +/- ~25rpm in order to avoid undesired acoustic interaction phenomena, the Sx2-PP set is the ideal choice for push-pull configurations as well as situations where two fans or more are operating side by side such as on 280mm radiators or in typical case cooling applications.

Highly optimised P/Q curve for all applications
The NF-A14x25 G2’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-A14x25 G2 is a true jack-of-all-trades with excellent performance in both static pressure and airflow demanding applications.
