> 3 dayThis product stopped working long before it should have... Cant return. I would have just replaced it with the same fan, but wasnt allowed that option. I have the same fans cooling my gaming PC. No problems.

> 3 dayBest fan available on the market. I purchased the cheaper China built fan and it died after 6 months. This fan (Tiawan) is solid, quiet, and a great buy with all the extra accessories. You get what you pay for!!!! I needed the 5v version for a Dauha NVR Security Camera system. With the added cords, I was able to adapt the default 3 wire cord to attach to the 2 prong motherboard connection. I really like the rubber mounts on the fan. Very quiet and moves a good amount of air. The china built fan was very loud. I would buy this again. Its worth every penny.

Greater than one weekIve had bad luck with these tiny fans. This one is an exception. Very quiet, good construction. The wiring is very stout. I was impressed with both the packaging and the materials used. Im very happy with this purchase!

> 3 dayI put two of these with the 52pi ice tower in push pull on my Pi4. they work great in comparison to the stock fans. This are a little quieter but make MUCH less vibration. They supply everything you need in the package to make this work with your pi, except the leads to connect it onto the pi board, so you will need to cannibalize an old pi fan.

> 3 dayWorked perfectly, and included quality mounting hardware as well as cable adapters. I purchased this to use with a Raspberry Pi model B, and drilled a hole for the fan, and mounting holes to the side of a cheap case in order to use it.
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 ChannelsThe 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 BearingThe 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 sizeThanks 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 MicrostructuresWith 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. |
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.
