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

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 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.

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.

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.

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?

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

These are the best fans ever. Very quiet, easy to spin, move a lot of air and made of quality materials. They are a little on the expensive side, but thats because quality is more expensive.

This fan is quiet, feels well built and works perfectly with my Jetson Nano kit.

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.

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