NF-A4X10 5V Noctua NF-A4x10 5V fan, 40 mm

The NF-A4x10 5V is a special 5V version of Noctua's highly optimized silent 40x10mm premium fan, which uses the AAO frame system and advanced aerodynamic design measures such as Flow Acceleration Channels. The smooth commutation Drive technology and the reference class bearing SSO2 guarantee excellent running smoothness and excellent long-term stability. Modular cabling, the OmniJoin™ adapter set and a 6-year manufacturer's warranty make the NF-A4x10 5V a premium solution for demanding 5V applications.

5V version Especially for devices in the areas of network and storage, 40mm fans with 5V are often used. With the same operating voltage and the supplied OminiJoin™ adapter set, which allows connection to proprietary plugs, the NF-A4x10 5V is ideal for replacing noisy or defective 5V 40mm fans.

Flow Acceleration Channels The impeller of the NF-A4x10 is equipped with so-called flow acceleration channels on the suction side. The acceleration of the air flow in the critical outer regions of the fan blades reduces the suction-side vortex-ablation, resulting in higher efficiency and lower turbulence-related noise emission.

Reduced Engine Lift Size Thanks to an optimized, compact engine design, the hub area of the NF-A4x10 is significantly smaller than with conventional 4cm fans. Thus, a larger blade area could be realized, which contributes to the superior pressure and flow rate of the NF-A4x10.

Stepped Inlet Design The stepped inlet area of the causes more turbulence in the inlet. This facilitates the transition from laminar to turbulent flow, which is better attached to the frame (flow attachment) and thus increases the suction capacity of the fan, especially when the intake area is limited.

Integrated Anti-Vibration Pads The anti-vibration pads, made from extra-soft silicone, reduce the transmission of minimal vibrations and are compatible with all standard screws as well as standard mounting systems or fan clips used in CPU coolers.

Smooth Commutation Drive 2 The latest, further developed version of Noctua's SCD drive system guarantees outstanding smoothness by eliminating torque fluctuations and switching noises. This makes the NF-A4x10 surprisingly quiet even from close proximity.

SSO2 Storage system The NF-A4x10 is equipped with the further optimized second generation of Noctua's proven SSO storage system. At SSO2, the rear magnet sits closer to the fan axis, resulting in even better stabilization, resulting in further improved precision and durability.

3 to 2-pin adapter and reverse polarity protection The NF-A4x10 is supplied with an adapter from 3-pin Molex to 2-pin connectors, which are used on many graphics cards as well as network and storage solutions. An integrated diode provides reverse polarity protection when connected via 2-pin connectors.

OmniJoin™ Adapter set Since many devices, in which 40mm fans are used, have proprietary fan connectors, the NF-A4x10 is supplied with Noctuas OmniJoin™ adapter set. Simply cut off the cable from the original fan, attach it to the adapter with the supplied 3M Scotchlok™ terminals and you can also operate the NF-A4x10 on proprietary connections!

Comprehensive Connectivity Options While the 20cm short primary cable helps to avoid cable clutter in typical applications, the included 30cm extension provides extra range for all cases. Both cables are fully sheathed.
