Noctua NF-A12x25 G2 PWM

The Noctua NF-A12x25 G2 PWM is a 120 mm fan with dimensions of 120×120×25 mm in a square frame design, featuring mounting hole spacing of 105×105 mm. It is designed for use in PC cases, liquid cooler radiators, and tower CPU coolers. The fan connects via a 4-pin PWM connector (A2543-4PIN or compatible) and supports speed control from 0 to 1800 RPM, including a complete stop mode at 0% PWM (0 RPM); at 20% PWM the speed is approximately 360 RPM. Maximum performance is rated at 107.3 m³/h (63.15 CFM) with static pressure up to 3.14 mm H₂O and noise levels up to 22.5 dB(A). The package includes the low-noise adapter NA-RC7, which limits maximum speed to 1500 RPM; in this mode the fan delivers up to 87.2 m³/h, 1.71 mm H₂O, and 18.1 dB(A). The fan is equipped with an SSO2 bearing and rotates counterclockwise. The frame is made from PBT ABS GF30, the impeller from LCP GF30, and the vibration-damping inserts are silicone; dimensions with inserts are 120×120×27 mm, and weight is 195 g. Power is supplied at 12 V (minimum starting voltage 7 V, maximum permissible voltage 13.2 V), with power consumption up to 1.8 W and current draw up to 0.15 A. The cable measures 200 mm (26 AWG) and is covered with braided sleeving; using the NA-EC1 extension the length can be increased to 500 mm. Included are the NA-YC1 splitter, four NA-AV2 vibration-damping mounts, NA-AVG1 damping pad, and mounting screws. The fan is rated for operation between -10 and +60 °C and features an IP50 protection rating.
