    Not much to say about it. Its a Noctua fan. Quality is always great, its nice and quiet, not a big fan of the color but my case doesnt have a window so Im not upset about it. I dont think Ive ever regretted buying a noctua fan.

    Awesome cooling fan. Works great with ODROID C2, brought temps down from 69C to 32C. Extremely quiet and has a good airflow. Definitely worth the money.

    Works great (with a 3d-printed mounting kit). Now my DC will outlive me, and stay nice and cool.

    Its definitely quite, using it currently for my Valve Index and it you can barely hear it. Does improve the heat dissipation from the headset quite well as it takes more ore less 1.5-2.0x longer (FOR ME) to have to take it off for being too hot.

    Piece of JUNK product screw that came with the product did not fit. when you try to contact customer Service from Noctua good luck getting any support. JUNK GARBAGE product and never again.

    I purchased a couple of these to replace the cheap fans used in an Amcrest Security Camera DVR system and wow, what an amazing difference. It is super quiet and I can barely tell the system is running anymore. I will definitely keep Noctua fans in mind for future builds.

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.
