Feature

- Flow Acceleration Channels; Reduced Motor Hub Size
- Integrated Anti-Vibration Pads; Smooth Commutation Drive 2; SSO2 Bearing
- Low-Noise Adaptor for full flexibility
- 3 to 2-pin Adaptor and Polarity Protection; .Thanks to its streamlined, compact motor design, the Noctua NF-A4x10’s motor hub is smaller than with conventional 4cm fans. This allows for more blade surface area and thus contributes to the NF-A4x10’s superior airflow and pressure performance.
- Extensive cabling options The NF-A4x10 impeller features suction side Flow Acceleration Channels. By speeding up the airflow at the crucial outer blade regions, this measure reduces suction side flow separation and thus leads to better efficiency and lower vortex noise

Featuring advanced aerodynamic design measures such as Flow Acceleration Channels and Noctua’s AAO frame, the NF-A4x10 FLX is a highly optimised, premium quality quiet fan in 40x10mm size. Smooth Commutation Drivetechnology and Noctua’s reference class SSO2 bearings ensure superb running smoothness and excellent long-term stability. Topped off with modular cabling and a Low-Noise Adaptor and OmniJoin Adaptor Set,, the NF-A4x10 is a premium choice for the highest demands.

AAO frame
Noctua’s AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads as well as Noctua’s proprietary Stepped Inlet Design and Inner Surface Microstructures, both of which further refine the fan’s performance/noise efficiency.
