## Summary description

Noctua NF-A4x10 5V PWM is a 40 mm computer case fan operating at 5 V with PWM control. It delivers up to 8.9 m³/h airflow at 1000–5000 RPM, noise up to 19.6 dB and typical power consumption 0.35 W. Features SSO bearing, anti-vibration pads, 4-pin PWM cable (0.2 m), included screws and MTTF ~150,000 h for reliable compact cooling.

## Long description

The Noctua NF-A4x10 5V PWM is a compact 40×10 mm cooling fan designed for efficient, low-voltage applications. It incorporates advanced aerodynamic features such as Flow Acceleration Channels and an AAO frame to improve airflow and reduce noise while operating at 5V. The fan uses Noctua’s custom NE-FD3 PWM controller with Smooth Commutation Drive technology and SSO2 bearings to provide smooth rotation and long-term stability. Modular cabling and the included OmniJoin adaptor set enable flexible installation, and the product is covered by a six-year manufacturer’s warranty.
Advantages
This 5V PWM fan delivers a wide rotational speed range (approximately 1000–5000 RPM) and a compact 40 mm diameter suitable for tight spaces. Aerodynamic optimisations increase airflow efficiency while keeping acoustic levels low. The integrated NE-FD3 PWM IC ensures precise PWM control and smooth commutation, and the SSO2 bearing type offers reliable long-term operation. Modular cabling and the OmniJoin adaptor set simplify connection options for diverse system layouts.
Suitable for
Small form-factor PCs and mini-ITX builds
Compact industrial and embedded systems running at 5V
Cooling for add-on cards, single-board computers and tight enclosures

How to use
Install the fan in the intended 40×10 mm mounting location using the appropriate screws or rubber mounts. Connect the PWM cable to a compatible 5V PWM header or use the supplied OmniJoin adaptors to match your system’s connector. Configure fan speed control in the host device or BIOS/firmware via PWM signals to achieve the desired balance of airflow and noise. Ensure the airflow orientation matches your cooling layout and avoid obstructing the intake or exhaust paths.
Usage recommendations
For reliable operation, maintain dust-free intake and exhaust areas and replace or clean filters regularly. Use PWM control to limit maximum speed in noise-sensitive environments and verify that your system provides a 5V PWM signal compatible with the fan’s requirements.
