08-03-2026There are a lot of PC fans out there, but don’t get me wrong — the Noctua NF-A14x25 G2 PWM chromax.black is simply on another level.It gives you everything in one package: insane performance, ultra-quiet operation, and a premium stealth look that fits perfectly into any high-end build.Airflow is strong, static pressure is excellent, and the noise levels are unbelievably low. The build quality is exactly what you expect from Noctua — engineered, precise, and built to last.If you want fans that look good, perform even better, and stay whisper-quiet, this is the one. 100% recommended. Easy 5 stars.

08-03-2026Been using the Original NF12 fans for 10 years now! Which are still running perfectly fine. Just got 4 of these for a new case!Came back to edit this review and after running them for few days, all I gotta say is "Damn these are nice"

08-03-2026A lot of money for a fan but coming from my old Corsair sp120’s, these are extremely quite and move a ton of air. Amazing quality as expected from Noctua. Would recommend in all blackout builds.

Award-winning NF-A14x25 G2 design
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, 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.
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.
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.
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.
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.
