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

I purchased this fan as a replacement for the one which came with ICY DOCK ToughArmor HDD enclosure. I went with Noctua brand because of the reviews and I am really impressed with the product. The build quality is pretty good and noise level is perfectly suited for desktop PC installation. I was looking for a fan that can operate quietly and at the same time provide adequate airflow into the HDD enclosure. This product lives up to its great reviews and reputation. There is nothing much for me to say, I would definitely recommend it.

Perfectly silent, and brilliantly cools my jetson nano 4gb.

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

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

Installed on my Jetson Nano. Works great.

Im using this with the Jetson Nano. You cant hear it at all, even at full speed!

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

Super quiet fan. My workflow improved and I can record now without the fan Boise in background.

works well to keep my 3d printer cool

Excellent fan but could have been a lower price.
