Noctua NF‑A12x25 PWM 120 mm Fan

The Noctua NF‑A12x25 PWM 120 mm Fan is an award‑winning, ultra‑high‑efficiency case fan engineered for both airflow and static pressure excellence, making it ideal for heatsinks, radiators, or chassis cooling.

Award‑Winning Engineering & Aerodynamic Mastery

Flow Acceleration Channels & Ultra-Tight Tip Clearance

The NF‑A12x25 features a record-tight 0.5 mm tip clearance enabled by Sterrox® liquid-crystal polymer blades. Combined with Noctua’s Flow Acceleration Channels and AAO frame, it delivers outstanding mid‑range static pressure and airflow with minimal turbulence.

SSO2 Bearing & Smooth Commutation Drive

Equipped with Noctua’s second-generation SSO2 bearing and CNC-milled brass shell, plus the NE-FD1 PWM IC with Smooth Commutation Drive technology, the fan runs with exceptional precision, durability, and near-silent PWM operation.

Low-Noise Adaptor Included

Ships with a low-noise adapter (L.N.A.) that caps maximum speed at ~1,700 RPM for quieter use—or allows full 2,000 RPM performance when needed.

Designed for Versatile Performance

Optimized for Heatsinks, Radiators & Chassis

The NF‑A12x25 delivers a balanced P/Q curve, outperforming many other 120 mm fans in both static pressure scenarios (like radiators) and airflow-focused setups (like case intake/exhaust).:[oaicite:4]{index=4}

Extensive Accessories Package

Includes standard anti-vibration mounts, a watercooling radiator gasket, PWM Y-cable, extension cable, and screws—making it ready for various mounting scenarios.
