Noctua NF-A4x20 5V PWM, Premium Quiet Fan, 4-Pin, 5V Version (40x20mm, Brown)

Very high quality fan. I needed to cool down a bit a bucket converter(step down from 36V to 12V), and this fan keep the converter very nice and cool. Too much heat is not good for you baby, that how the song says?

Installed on my Jetson Nano. Works great.

Works great!

I bought this fan for use with the Nvidia Jetson Nano. The Nano automatically turns the fans on and off on demand. Cant tell is the fan is on by noise generated because there isnt any. The only problem I had installing it was because the supplied screws were too short and didnt fit the holes in the heat sink. Temporarily used round toothpicks to hold it until I can find the proper screws.

Product advertised as quiet, sounds like a rocket ship. Too loud for silent setup use. Will be returning.

easy to install, will buy again

Plugged right into my nVidia Jetson Nano. Variable speed works great.

Just to be safe since my ASUS Prime Z390 a mother board was air-cooled, added this fan since the motherboard supported a 40 or 50 mm fan for cooling the heatsink on M2 SSD. Also attached temp sensor to M2 heatsink, Asus software controls fan speed automatic, great solution.

The rubber anti-vibration pads can squeeze out and detach if you sandwich the fan between a fan guard and a Jetson Nanos heat sink then bolt it down tight.

Im using this to cool a Raspberry Pi running a 3d printing server. It would overheat causing the printer to stutter - but no longer. This fan is impressively small delivering impressive airflow and virtually silent. Im very satisfied.
