Noctua NF-A4x10 FLX fan

Noctua NF-A4x10 FLX — compact and quiet fan

For users looking for a quiet fan with high reliability, the Noctua NF-A4x10 FLX is the ideal solution. With its compact dimensions of 40 × 40 × 10 mm, it is perfect for small and space-saving systems. The fan offers flexible speed control at 4500 rpm or 3700 rpm when using L.N.A., allowing you to adjust performance and noise as needed. Aerodynamic features such as Flow Acceleration Channels and SSO2 bearing ensure quiet operation, excellent performance and a long service life. A 6-year warranty underlines its reliability.

Aerodynamic innovations for better performance

The Noctua NF-A4x10 FLX is equipped with AAO frame (Advanced Acoustic Optimization) technology, which minimizes vibrations and improves airflow. Flow Acceleration Channels on the fan blades accelerate the airflow, which increases performance while reducing noise. These features are key to achieving 1.78 mm H2O static pressure, ideal for applications where resistance needs to be overcome, such as in coolers or tightly packed systems.

Flexible speed control and quiet operation

The fan supports two speed settings: 4500 rpm for maximum performance and 3700 rpm when using L.N.A. for lower noise. With a maximum noise level of 17.9 dB(A), the fan remains almost inaudible during operation, which will be appreciated by users who prefer their systems to operate quietly. Thanks to its low noise level and the ability to adjust the speed, this fan is an ideal choice for home, office and industrial applications.

Compatibility and practical accessories

The Noctua NF-A4x10 FLX is designed with a focus on wide compatibility. With the universal 3-pin connector and the supplied NA-AC2 adapter, installation is quick and easy. The fan is also equipped with an extension cable and anti-vibration mounts, which further facilitate installation and minimize the transfer of vibrations to surrounding components.
