Noctua NF-A14x25 G2 PWM Fan, 140mm, Brown

This is a 140 mm case fan engineered for applications requiring high static pressure and optimized airflow within PC cooling systems. It operates across a rotational speed range configurable from 0 to 1500 RPM, allowing for precise control via the standard 4-pin Pulse Width Modulation (PWM) connection. The fan delivers a maximum airflow of 155.6 m³/h and achieves a static pressure rating of 2.56 mmH2O under full performance specifications. This profile makes the unit suitable for constrained applications such as radiator or heatsink mounting, in addition to standard case ventilation.

The unit incorporates an advanced SSO2 bearing system, designed for operational stability and a rated Mean Time To Failure (MTTF) of 150,000 hours. The specialized Sterrox LCP (Liquid-Crystal Polymer) material used in the impeller contributes to structural rigidity and minimizes potential vibrational noise generation. Under maximum operation, the acoustic output is rated at 24.8 dB, with a low-noise adapter included for reduced operational thresholds. Power requirements are standard 12 V DC, drawing a maximum current of 0.19 A, resulting in a typical power consumption of 2.28 W.
