> 3 dayAdded to my Thrustmaster TMX wheel as the motor has been running hot because it’s a cheap wheel and I should have bought a G920. Perfect sized replacement from the stock fan and pushes more air out the side vent.

> 3 dayBy far the best far on the market. I used mine for additional cooling in my dreamcast.

> 3 dayWas looking for a fan to keep my raspberry pi cooler while I have it mounted on to a ender 3 3D printer and it does pretty good, even with it being in inside a enclosure tent for the printer.

> 3 dayPerfect. I used these fans to replace the POS fans that came with amcrest DVR. They are working very well and are super quiet.

Greater than one weekDespite wondering why I was paying $14 for a tiny fan, I dont regret this purchase. I have this installed in a custom case for a Comma.ai self-driving device in my car. It keeps the device cool and is nearly inaudible with the car running. I can also trust that this thing will outlast the Comma device itself. A cheaper fan may have accomplished one or two of these things, but it sure wouldnt be able to do all 3.

> 3 dayThough small, this fan upholds Nocuta’s reputation. It’s very well made, virtually silent, and moves a decent amount of air for its size. I’m running it at 3.3V without issue

> 3 dayIn order to fit this into your Dreamcast you have to buy a 3D printed fan mount adapter and wire adapter. It works great, and is much more silent than the original fan inside. My heavily modded DC stays nice and cool, and super quiet. Love 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.
