Noctua - NF-A4x10 Fan 40x10mm 5V, 3 pin, 4500rpm
Featuring advanced aerodynamic design measures such as Flow Acceleration Channels and an AAO standard frame, the NF-A4x10 5V is a dedicated 5V version of Noctuas highly optimised, premium quality quiet 40x10mm fan. Smooth Commutation Drive technology and Noctuas reference class SSO2 bearing guarantee superb running smoothness and excellent long-term stability. Topped off with modular cabling, the OmniJoin™ Adaptor Set and 6 years manufacturers warranty, the NF-A4x10 5V is a premium choice for demanding 5V applications.
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.
5V version Many devices such as network or storage solutions use 5 volt 40mm fans. With the same operating voltage and the included OmniJoin™ adaptor set that makes it compatible with proprietary fan headers, the NF-A4x10 5V is ideal for replacing noisy or broken 5V 40mm fans.
Focused Flow 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. button
Varying Angular Distance Reduced Motor Hub Size Thanks to its streamlined, compact motor design, the NF-A4x10s motor hub is smaller than with conventional 4cm fans. This allows for more blade surface area and thus contributes to the NF-A4x10s superior airflow and pressure performance.
Heptaperf AAO Frame Noctuas AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads as well as Noctuas proprietary Stepped Inlet Design and Inner Surface Microstructures, both of which further refine the fans performance/noise efficiency. button
Stepped Inlet Design Stepped Inlet Design Noctuas 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. button
Inner Surface Microstructures 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. button
Integrated Anti-Vibration Integrated Anti-Vibration Pads Integrated Anti-Vibration Pads made from extra-soft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard mounting systems and fan clips used on heatsinks.
SSO2 Smooth Commutation Drive 2 The latest version of Noctuas 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 distance. button
SSO2 SSO2 Bearing The NF-A4x10 features the further optimised second generation of Noctuas renowned, time-tested SSO bearing. With SSO2, the rear magnet is placed closer to the axis to provide even better stabilisation, precision and durability. button
5V 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.
SSO2 OmniJoin Adaptor Set Many devices featuring 40mm fans use proprietary fan headers, so the NF-A4x10 comes with Noctuas OmniJoin Adaptor Set. Just cut the original fans cable, fix it to the adaptor using the supplied 3M Scotchlok™ connectors and you can plug the NF-A4x10 to proprietary fan headers! button
Cabling Options Extensive Cabling Options The fans 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.
Warranty 6 years manufacturers warranty Noctua fans are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the NF-A4x10 features an MTBF of more than 150.000 hours rating and comes with a full 6 years manufacturers warranty.
