Noctua NF‑A14x25 G2 PWM 140mm Next‑Gen Quiet Performance Fan – 1500RPM

Noctua NF‑A14x25 G2 PWM – 140mm Fan

The Noctua NF‑A14x25 G2 PWM is a next‑generation 140mm cooling fan engineered for exceptional airflow, static pressure, and ultra‑quiet operation. Built using high‑grade liquid‑crystal polymer (LCP) with glass‑fiber reinforcement, it offers superior rigidity and reduced vibration compared to traditional plastics. This allows for tighter tolerances and improved aerodynamic performance.

With PWM control and speeds up to 1500 RPM, the NF‑A14x25 G2 delivers powerful cooling while maintaining a low noise level of just 24.8 dB(A). A Low‑Noise Adapter is included, reducing the maximum speed to 1250 RPM for even quieter operation. Its high static pressure of 2.56 mmH2O and airflow of 91.58 CFM make it ideal for radiators, high‑density heatsinks, and demanding airflow scenarios.
