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

Works great!

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.

This fan is quite and keeps the Nano from throttling back during extensive AI/DL, however the cable is way too long for a NVIDIA Nano and had to be bunched up between the Nano heat sink and the top of the SBC case.

I was blow away by the quality of this fan. The details, the material feels like it will last a really long time. You can tell people did lots of research.

For this tiny size, these are amazingly quiet and effective. Really a marvel.

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.

Its a little tall in proportion to the Jetson Nano but it works great.

This is a quiet operating fan and it cools extremely well akso. It is easy to install and a Quality product!

Excellent fan. Very low, if any, noise. I dont hear it. Mounted as a VRM cooler on my ASUS Prime Z370-A mobo.

This 40x20mm fan fits Waveshare case for Nvidia Jetson Nano, 4-pin connector fits the board too. Software controlled. Well made and whisper quiet.
