Full product description
Quiet cooling for compact 5V electronics
The Noctua NF-A4x20 5V provides quiet airflow in small enclosures that need a 5V fan. Its 40 × 40 × 20 mm design combines airflow-guiding blade channels with Noctua's SSO2 bearing for smooth operation, and soft anti-vibration pads help reduce vibration transfer. The included adapters and extension cable give you connection options for a compatible 5V installation.
5V only: This is the three-pin NF-A4x20 5V model. Connecting it to a 12V supply, including a typical 12V PC fan header, can damage it. Check voltage, connector wiring, mounting-hole spacing and clearance before fitting.

What's in this package
- One Noctua NF-A4x20 5V fan
- OmniJoin adaptor set for adapting to compatible proprietary connections
- 3:2-pin adaptor and extension cable

New in its original retail box. Use the supplied connection instructions; the OmniJoin kit does not make a 12V device compatible with this 5V fan.
The retail packaging lists a six-year Noctua manufacturer warranty; coverage is subject to the manufacturer's terms and eligibility.
