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

Designed to cool The NF-A4x10 impeller features suction side Flow Acceleration Channels to reduce suction side flow separation for better efficiency and lower vortex noise. The reduced motor hub size allows for more blade surface area and thus contributes to the NF-A4x10’s superior airflow and pressure performance.
Cools quietly Noctua’s AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads as well as Noctua’s unique Stepped Inlet Design and Inner Surface Microstructures, both of which further refine the fan’s performance/noise efficiency. The Low-Noise Adaptor (L.N.A.) is supplied to reduce the maximum fan speed from 4500 to 3700rpm so that it can be fine-tuned for superior airflow or maximum quietness. And the latest version of Noctua’s advanced Smooth Commutation Drive system ensures superb running smoothness by eliminating torque variations and switching noises.
SSO2 Bearing The NF-A4x10 features the further optimised second generation of Noctua’s renowned, time-tested SSO bearing. With SSO2, the rear magnet is placed closer to the axis to provide even better stabilisation, precision and durability.
3 to 2-pin Adaptor and Polarity Protection The NF-A4x10 comes with an adaptor from 3-pin Molex to the 2-pin connectors used on many graphics cards or network and storage devices. An integrated diode provides polarity protection on 2-pin connections.
OmniJoin Adaptor Set Many devices featuring 40mm fans use proprietary fan headers, so the NF-A4x10 comes with Noctua’s OmniJoin Adaptor Set. Just cut the original fan’s cable, fix it to the adaptor using the supplied 3M Scotchlok connectors and you can plug the NF-A4x10 to proprietary fan headers!
Extensive Cabling Options The fan’s short 20cm primary cable minimises cable clutter in typical applications while the supplied 30cm extension provides extended reach when necessary. Both cables are fully sleeved.
