Description
Information
Noctua NF-A14x25 G2 PWM 140mm Fan
A 140mm PWM fan for quiet PC cooling
Designed for case airflow, heatsinks and water cooling radiators

140mm Cooling Design
The NF-A14x25 G2 PWM uses a 140 x 140 x 25mm square frame
It is designed as an all-round fan for airflow and static pressure applications
The 4-pin PWM connection allows automatic speed control through compatible fan headers

Controlled Cooling Performance
The fan operates across a 0–1500 rpm speed range
0 rpm operation is supported at 0% PWM for semi-passive cooling setups
The included Low-Noise Adaptor can reduce the maximum speed to 1250 rpm
For Cases and Radiators
The aerodynamic design is made for both case cooling and radiator use
A pre-installed NA-AVG2-LR anti-vibration gasket helps create a tighter seal on radiators
Maximum airflow is rated at 155.6 m³/h, with maximum noise of 24.8 dB(A)

Practical Installation Bundle
The fan includes a Low-Noise Adaptor, PWM splitter cable and 30cm extension cable
Anti-vibration mounts, load-relief pads, radiator gasket and fan screws are included for flexible installation
Noctua SSO2 bearing and Sterrox LCP impeller material support stable long-term cooling use
