Noctua NF-A14x25 G2 PWM Chromax Black 140mm 1500rpm Cooling Fan
State-of-the-Art Quiet Cooling Performance
The chromax.black version of the award-winning NF-A14x25 G2 140mm fan delivers cutting-edge quiet cooling performance for PC cases and water-cooling radiators in a sleek all-black design. Succeeding the iconic NF-A14, the NF-A14x25 G2 has quickly become the new benchmark for premium, silent 140x25mm fans.
Advanced Aerodynamic Engineering
With the novel Progressive Bend impeller design featuring a Centrifugal Turbulator hub, winglets, and an ultra-tight 0.7mm tip clearance, the G2 model provides a major leap in performance-to-noise efficiency. Whether used for low-impedance airflow scenarios like case cooling or high-impedance pressure-demanding applications such as radiators, the etaPERF motor with SupraTorque technology guarantees stable performance even under heavy resistance.
chromax.black Edition
The chromax.black edition pairs the NF-A14x25 G2’s Sterrox liquid-crystal polymer impeller and full feature set with an elegant all-black look. From the impeller to the frame, anti-vibration pads, gasket, mounts, screws, and cables—everything is finished in black. Users can also customize the fan with optional coloured anti-vibration pads.
Premium Durability and Reliability
Equipped with Noctua’s trusted SSO2 bearing, an MTTF exceeding 150,000 hours, the NF-A14x25 G2 PWM chromax.black ensures long-term stability, quietness, and top-tier performance in any build.
Award-Winning NF-A14x25 G2 Design
Delivering a significant performance boost over the first-generation NF-A14, the NF-A14x25 G2 has received worldwide praise and numerous awards from hardware experts. It stands as a new favourite among silent-cooling enthusiasts seeking uncompromising quality.
SupraTorque™ Technology
Most fans slow down when encountering back pressure from radiators or heatsinks. Powered by the new NA-FD6 driver IC, Noctua’s SupraTorque™ compensates by delivering additional torque when needed, maintaining stable RPM regardless of airflow resistance for consistent cooling in demanding conditions.
Ultra-Tight Tip Clearance
Featuring a record-setting 0.7mm tip clearance between the impeller and fan frame, the NF-A14x25 G2 minimises leak flow and improves efficiency against back pressure. This allows significantly better performance on radiators and heatsinks compared to conventional 140mm fans.
