Noctua NF-A14x25 G2 PWM

The Noctua NF-A14x25 G2 PWM is a next-generation 140 mm case or radiator fan in the classic square 140 × 140 × 25 mm format, designed for systems where high airflow, controlled pressure, and predictable PWM-controlled operation are essential. The declared speed range is 0 to 1500 RPM, with maximum airflow of 155.6 m³/h (91.58 CFM), static pressure of 2.56 mm H2O, and noise level up to 24.8 dB(A). The construction features Noctua's proprietary Sterrox LCP material, a minimal gap between the impeller and frame, and the new Progressive Bend blade geometry, which delivers superior efficiency both on radiators and as a case fan. The fan connects via a standard 4-pin PWM connector, operates on 12 V, and can be installed in systems requiring stable RPM control without a separate hub. The package includes a Low-Noise Adaptor, PWM splitter, and extension cable, simplifying integration into large cases or multi-fan configurations. The Noctua NF-A14x25 G2 PWM is ideal for CPU coolers, liquid cooling systems, front or top case ventilation, when you need a high-end 140 mm fan that prioritizes aerodynamic efficiency, precise PWM control, and consistent performance under load.
