    This a great fan. Comes with a 3 pin to 2 pin convertor. Plugged in into raspberry pi 3b pin 4 (5v) and 6(ground) without an issue. Temperature dropped by 20 degrees celcius. Great value!

    As expected, premium quality. Low noise. Way quieter than the fan came with raspberry pi 4 Cana Kit. Perfect for my mini raspberry pi 4 home server.

    Wow this is a QUIET tiny fan . Used it to replace a different brand 40mm fan and the noise reduction was immediately apparent. I have to stick my finger in the fan to even know its working its that quiet.

    I used this fan as a replacement in a switch and was a little surprised by the volume of air it moved - so much that the air flow is audible. No bearing noise, just a whoosh.

    Fan is extremely quite and comes with all sorts of mounting items and extra connectors.

    I used this fan in a rather odd repair. I have a wireless phone charger that has a built in fan, after about 6 months of use the fan starting to make a grinding noise. I figured what the heck lets have some fun and take it apart see what kind of fan is in there.

    silent theyre not! the description made them sound like they have some breakthrough design with the fan blades that would make these super quite. the sound level are about the same as my iMac in a completely quiet room. a very audible steady fan noise. good mounting and connector options included.

    The old fan on my Lorex was so loud right out of the box. I have had this one installed for a few months and it is still quiet, plus I can tell it has much more air flow.

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 Noctua’s highly optimised, premium quality quiet 40x10mm fan. Smooth Commutation Drive technology and Noctua’s reference class SSO2 bearing ensure superb running smoothness and excellent long-term stability. Topped off with modular cabling and the OmniJoin Adaptor Set, 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 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.

Please Note: Being a 5V fan, the NF-A4x10 5V cannot be run at 12V and will be damaged when used with typical 12V power sources such as PC motherboard fan headers.

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.

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.

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.

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.
