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

Quiet as expected.

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.

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.

Programmable fan for my Jetson Nano.

Its quiet and blows, it goes great in my 1u server.

I should have click the buy button on the two(2) fans package from a different maker for roughly the same price. You are paying more marketing , and silly fold out displays, tons of fancy packaging, it come packed in alot of plastic which could be cardboard, three sets of oddball extra cables just throw 50% of the package contents in the trash. I am using this on a jetson nano and it sounds a performs the same as the stock one. I used thin guage wire to attach the fan and just twisted it to sung it down. All the connectectors that cam with it i just tossed the the trash.

I’m using this to cool my Jetson Nano. It works great and it’s so quiet I have to look at it to see if it’s running.

Title says it, this fan does a great job at cooling a raspberry pi 4. With a little modification to the case

Installed on a Jetson Nano. I had to buy M2.5 x 8mm screws / washers and nuts. Fan will not turn unless the tempature is high or you turn it on via a software command.

Awsome for using on you GPUs. I have dual cards and it fits right in between them, and keeps them cool beautifully
