The Noctua NF-A4x20 PWM is a 40x20mm fan designed for cooling in space-constrained applications. Its compact frame is suitable for small form factor (SFF) PCs, network-attached storage (NAS) units, and other hardware where ventilation is limited. The fan connects via a 4-pin PWM header, which enables motherboards or dedicated controllers to automatically adjust rotational speed based on thermal loads. This functionality allows the system to balance cooling requirements with acoustic output.
At its maximum rotational speed of 5000 RPM, the fan produces an airflow of 5.53 CFM and a static pressure of 2.26 mmH2O, making it effective for pushing air through dense grilles or small heatsinks. The unit is built with an SSO2 bearing, which is designed for operational stability and a long lifespan. The package includes anti-vibration mounts to dampen operational resonance, as well as a low-noise adapter, a PWM splitter, and an extension cable to aid installation.
Key Features:- Measures 40 x 40 x 20 mm for compact systems
- Features a 4-pin PWM connector for automatic speed control
- Operates within a 1200 to 5000 RPM speed range
- Utilizes an SSO2 bearing for operational longevity
- Generates 2.26 mmH2O of static pressure
- Includes anti-vibration mounts and installation accessories
