Noctua NF-A4x10-5V 40mm Fan

Noctua NF-A4x10-5V 40mm Fan

***Being a 5V fan, the NF-A4x10 5V can not be run at 12V and will be damaged when used with typical 12V power sources such as PC mainboard fan headers.***

Featuring advanced aerodynamic design measures such asFlow Acceleration Channelsand anAAOstandard frame, the NF-A4x10 5V is a dedicated 5V version of Noctuas highly optimised, premium quality quiet 40x10mm fan.Smooth Commutation Drivetechnology and Noctuas reference classSSO2bearing guarantee superb running smoothness and excellent long-term stability. Topped off with modular cabling, theOmniJoin Adaptor Setand 6 years manufacturers warranty, the NF-A4x10 5V is a premium choice for demanding 5V applications.

5V version

Many devices such as network or storage solutions use 5 volt 40mm fans. With the same operating voltage and the included OmniJoinâ„¢ adaptor set that makes it compatible with proprietary fan headers, the NF-A4x10 5V is ideal for replacing noisy or broken 5V 40mm fans.

Flow Acceleration Channels

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.

Reduced motor hub size

Thanks to its streamlined, compact motor design, the 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.

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.

Noctua's Stepped Inlet Design adds turbulence to the influx in order to facilitate the transition from laminar flow to turbulent flow, which reduces tonal intake noise, improves flow attachment and increases suction capacity, especially in space-restricted environments.

Inner Surface Microstructures

With the tips of the fan blades ploughing through the boundary layer created by the Inner Surface Microstructures, flow separation from the suction side of the blades is significantly suppressed, which results in reduced blade passing noise and improved airflow and pressure efficiency.

Smooth Commutation Drive 2

The latest version of Noctua's advanced Smooth Commutation Drive system ensures superb running smoothness by eliminating torque variations and switching noises. This makes the NF-A4x10 remarkably quiet even at very close distances.

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.

OmniJoinâ„¢ Adaptor Set

Many devices featuring 40mm fans use proprietary fan headers, so the NF-A4x10 comes with Noctua's OmniJoinâ„¢ adaptor set. Just cut the original fan's cable, fix it to the adaptor using the supplied 3M Scotchlokâ„¢ 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.

6-year manufacturer’s warranty

Noctua fans are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the NF-A4x10 features an MTTF of more than 150.000 hours rating and comes with a full 6-year manufacturer’s warranty.
