Noctua NF-A4x10 5V, Premium Quiet Fan, 3-Pin, 5V Version (40x10mm, Brown)

I used this fan in a rather odd repair. I have a wireless phone charger that has a built in fan, after about 6 months of use the fan starting to make a grinding noise. I figured what the heck lets have some fun and take it apart see what kind of fan is in there.

The fan is quieter than a typical cheap fan you can find online. However, it doesnt seem to be as quiet as I would expect for a fan from Noctua especially at this price point. However, this being a 5V fan, it does work quite nicely off USB power (adapter required).

This is extraordinary, its unbelievably silent - is it on??? No more annoying humming/whirring of ordinary fans. Definitely worth it.

Great quiet fan. Used to replace extremely noisy fans in my security camera DVR. Would recommend.

Excellent, 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

Added 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.

Bought to for my clone mk3 prusa. Had to solder correct lengths wires. Works great. Silent

Quiet and gets the job done.

Worked 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.

My first impression was the packaging was over the top. Once I got into the contents it makes sense. Item is carefully packed and includes just about any mounting hardware or wiring adapter to do a very clean install on anything with minimum fuss. I used two of these in a 10 yr old US Robotics 24 port managed switch that runs on my desk. The original fans were too noisy as the switch was never intended for desktop/office use. Until this item came up in a search, I used the only other silent fan brand, which was only offered in a 12v version and required a somewhat ugly external power arrangement. Not to mention the last ones barely lasted a year. I am so glad to see this competitive and apparently high quality model offered in a 5v version. My switch is quiet and cool again, back to using the original 5v power supply off the board. Time will tell, but this brand/product may be my new go-to choice!
