> 3 dayThis keeps my Pi 4 temps super low and it is very quiet. Add in the Noctua quality and this is a no brainer.

> 3 dayI bought this Noctua since it had a reputation for being quiet and of high quality, mine was quite a bit louder than the crappy stock fan used to be in there. I might have got a dud but since I tossed the packaging right away now Im stuck with it.

> 3 dayBought for a RPI 4 ice tower. Didnt really need it but what the heck. Works very well and did drop temps by about 2 degrees over the cheap one. Was it worth it? Maybe, maybe not. Im happy though.

> 3 dayExcellent, high quality, QUIET fans. I used them to replace both fans in my originally very noisy Amcrest security camera DVR. I made a video to show I did it to hopefully help folks: https://www.youtube.com/watch?v=gEa-IAyuJeA

> 3 dayUsing this on my Ender 3 and had originally thought it did not work it was so quiet!! The PSU fan is now the loudest fan on my printer.

> 3 dayIt’s pretty quiet and blows pretty hard, I used it on a raspberry pi and My temps are about half of what they are with no fan

> 3 dayMine 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.

> 3 dayfirst time Ive used Noctua fan for a Raspberry Pi4. Im blown away, no pun intended. I replaced a chepo pi-fan came with a pi case. I can hardly hear it. Would buy again.
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.
