Noctua NF‑A12x25 G2 PWM 120mm Next‑Gen Quiet Performance Fan – 1800RPM

Noctua NF‑A12x25 G2 PWM – 120 mm 

The Noctua NF‑A12x25 G2 PWM is the second‑generation evolution of Noctua’s flagship 120mm fan, engineered for exceptional cooling efficiency, high static pressure, and ultra‑quiet operation. Built from reinforced liquid‑crystal polymer (LCP), the G2 series improves rigidity and reduces vibration, enabling tighter tolerances and superior aerodynamic performance.

With PWM control and speeds up to 1800 RPM, the NF‑A12x25 G2 delivers powerful airflow and high pressure, making it ideal for radiators, heatsinks, and restrictive chassis layouts. Despite its performance, it maintains whisper‑quiet acoustics at just 22.5 dB(A), and includes a Low‑Noise Adapter to reduce maximum speed to 1500 RPM for even quieter operation. A full accessory kit—Y‑cable, extension cable, anti‑vibration mounts, and radiator seal—ensures flexible installation.
