The Noctua NF-A4x10 5V PWM is a 40x10 mm fan engineered for specialized 5V applications. It is suitable for small-form-factor builds, network hardware, or embedded systems that use 5V fan power sources instead of standard 12V motherboard headers. The fan utilizes a 4-pin connector to support PWM speed control, allowing its rotational speed to be adjusted automatically between 1000 and 5000 RPM based on thermal load. This provides a dynamic balance between cooling performance and operational acoustics.
At maximum speed, this fan produces an airflow of 5.24 CFM and a static pressure of 1.95 mmH2O with a noise level of 19.6 dB. Its operational stability is supported by Noctua’s SSO2 bearing technology, a self-stabilizing oil-pressure bearing designed for longevity. The package includes a range of accessories to aid installation, such as anti-vibration mounts, fan screws, and a 30 cm extension cable. An OmniJoin adaptor set is also provided to facilitate connection to proprietary fan headers.

- Features a compact 40x40x10 mm frame for tight spaces
- Utilizes an SSO2 bearing for operational stability and longevity
- Includes an OmniJoin adaptor set for proprietary fan headers
- Supplied with a USB power adaptor for alternative power sources
- Provides rotational speeds from 1000 to 5000 RPM
