    I love Noctua fans for my desktop and I love Noctua fans for my SBC projects, too.

    Small but effective. Also quiet.

    Using on an odroid XU4 with the gdstime heat sink, fits the heatsink perfect, much quieter than stock. The Omnijoin Adapter is 4 pin and the fan is 3 pin, I realized this after I had spliced it to the original connector, ended up using the spare splices and hacking up the 3 to 2 pin adapter. Disappointing, but not enough to down rate the product.

    Mine came with a omnijoin adapter for a 4 pin connection. The fan has a 3 pin connection and it will not fit. Might increase my rating if noctua sends me the right part.

    I needed a 5v three-wire fan to replace a failed unit. The Noctua fan was a perfect fit. It is working fine, but it is too soon to comment on long-term durability. The kit came with numerous adapters that I did not need. I would have preferred a fan only option at a lower price.

    I replaced the fan in an old HP 26 port switch with this one. I added a resistor I had from another Noctua kit. It blows plenty of air to cool the switch and sounds much quieter. The switch gives a fault light, but otherwise works just fine. Ive been adding CAT6 wired internet to the rooms in my house. Wireless works, but nothing beats the hard line!

    Installation is easy with the rubber pull clips, quiet running

    Purchased this fan to cool a raspberry pi build. Prior to the install the unit was running at 55c. The unit runs right off the raspberry pi board and brought the temperature down to 34c. Did not think that this little fan would have that much of an impact. Another plus is that you cannot hear it running.

    I used one of these to replace the noisy fan in my Q-See DVR that I bought at Costco. This one is much quieter but not totally silent. Id say it is probably about half as loud as the original, so it is well worth it. Comes with every imaginable connector to adapt to whatever you have, which is nice. On a Q-See DVR, you will not need any of those adapters.

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.
