## Summary description

Noctua NF-A4x10 FLX is a 40 mm axial fan designed for computer cases and compact cooling applications. It operates at 12 V with a maximum speed of 4500 RPM and maximum current 0.05 A, providing airflow up to 8.2 m³/h. The fan is 10 mm thick, supplied as a single unit and suited for tight spaces where reliable low-profile cooling is required.

## Long description

The Noctua NF-A4x10 FLX is a premium 40 x 10 mm cooling fan engineered for compact spaces where efficient airflow and low noise are required. It combines Noctua’s aerodynamic innovations such as Flow Acceleration Channels, the AAO (Advanced Acoustic Optimisation) frame and a compact motor hub with SSO2 bearings to deliver stable, long-lasting operation. The FLX variant includes a Low-Noise Adaptor and OmniJoin Adaptor Set, multiple cabling options and a 6-year manufacturer’s warranty.
Advantages
The fan’s Flow Acceleration Channels and inner surface microstructures reduce suction-side flow separation and lower vortex and blade-passing noise while improving efficiency. Its reduced motor hub size increases blade surface area for better airflow and pressure. The AAO frame integrates anti-vibration pads, a Stepped Inlet Design and inner-surface treatments to further enhance acoustic performance. SSO2 Smooth Commutation Drive and optimized SSO2 bearings ensure very smooth running, improved stabilisation and long-term durability. Included accessories such as the Low-Noise Adaptor, OmniJoin set and extension cable provide installation flexibility.
Suitable for
Small form-factor PC cases and compact HTPC enclosures
GPU, network or storage device cooling that requires 40 mm fans
Applications with tight space constraints or restricted airflow channels
Key specifications

Anti-vibration pads integrated in frame
Warranty: 6 years manufacturer’s warranty; MTBF \>150,000 hours
How to use
Mount the NF-A4x10 FLX in the available 40 mm fan slot using standard screws or compatible clips; the integrated anti-vibration pads maintain compatibility with standard mounting systems. Choose the required connector type: use the 3-pin plug for conventional headers, the supplied 3-to-2-pin adaptor for devices with 2-pin connectors, or create a proprietary connection using the OmniJoin Adaptor Set and supplied 3M Scotchlok™ connectors. Use the 30 cm extension cable if additional reach is necessary. Fit the Low-Noise Adaptor to reduce maximum speed for quieter operation where appropriate.
Usage recommendations
For optimal performance in restricted spaces, position the fan to maintain straight, unobstructed intake/exhaust paths and use the L.N.A. when lower acoustics are preferred over maximum airflow. Verify polarity when using 2-pin connections; the integrated diode provides protection but correct wiring ensures reliable operation.
