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

The Noctua NF-A4x10 FLX is a 40mm fan with a slim 10mm profile, designed for use in space-constrained applications. Its reduced depth makes it suitable for compact PC cases, network-attached storage (NAS) units, and other small form factor systems where standard 25mm thick fans cannot be installed. This fan operates using a 3-pin connector, providing a fixed rotational speed for consistent airflow. The design prioritizes compatibility in tight enclosures while offering a dedicated cooling solution for small hardware components.

This model utilizes Noctua's SSO2 bearing for long-term mechanical stability and a Smooth Commutation Drive system to reduce operational noise. It operates at a maximum speed of 4,500 RPM, delivering up to 4.83 CFM of airflow and 1.78 mmH2O of static pressure. These specifications are appropriate for general chassis ventilation or for applications requiring airflow through moderately restrictive grilles. A Low-Noise Adaptor is included in the package, allowing users to reduce the fan's maximum rotational speed for quieter operation.
