5V Noctua NF-A4x10 40mm Fan Kit

The Noctua NF-A4x10 5V: A premium quality 40x10mm cooling fan designed for 5V applications (It moves A LOT of air). 

Key Features

Advanced Aerodynamics: The NF-A4x10 5V utilizes Flow Acceleration Channels on the impeller, which speed up airflow at the outer blade regions. This design reduces suction side flow separation, leading to better efficiency and lower vortex noise.

Compact Design: Thanks to its streamlined motor design, the fan's hub is smaller than conventional 40mm fans. This allows for more blade surface area, contributing to superior airflow and pressure performance.

AAO Frame: The Advanced Acoustic Optimisation (AAO) frame features integrated anti-vibration pads, a Stepped Inlet Design, and Inner Surface Microstructures. These elements work together to refine the fan's performance and noise efficiency.

Smooth Operation: The fan employs Smooth Commutation Drive technology and Noctua's SSO2 bearing, ensuring excellent running smoothness and long-term stability.
