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

Works great!

This worked perfectly. Made my printer so much quieter

Purchased to cool my raspberry pi. Modified the pinout a bit. Its quiet and circulates air well - true to Noctuas reputation.

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?

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

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.

Installed on my Jetson Nano. Works great.

Bought to replace noisy fans in a 1U unifi router enclosure. These are noisier, though theyre also much higher CFM.

Noctua is a get what you pay for brand. They are expensive fans. But quiet and reliable. Definitely made the router under my desk quieter. Unlike some of the cheaper quiet fans, these guys will run for years and stay quiet.

Excellent fan but could have been a lower price.
