Noctua NF-A4x10-FLX 5V 40 x 40 x 10 mm Case Fan - Beige/Brown

The Noctua NF-A4x10-FLX 5V is a compact fan with 40x10 mm dimensions, engineered for applications that require 5V power. It integrates Noctua's Flow Acceleration Channels and an acoustically optimized frame to enhance airflow and pressure performance within space-constrained systems. The fan is built around an SSO2 bearing, a hydro-dynamic bearing system designed for operational stability and a long service life. This model is suitable for specialized cooling in network devices, embedded systems, or custom builds that utilize 5V fan headers.

This fan operates at a maximum rotational speed of 4500 RPM, generating an airflow of 4.83 CFM at a noise level of 17.9 dB. It connects using a standard 3-pin header, serving as a direct replacement for stock fans in various electronics. The package includes a mounting kit with anti-vibration mounts to help decouple the fan from the chassis, which can reduce structure-borne noise. Its design prioritizes reliable, low-noise airflow over the high static pressure required for dense heatsinks or radiators.
