Noctua NF-A4x10 5V, Premium Quiet Fan, 3-Pin, 5V Version (40x10mm, Brown)

Whisper quiet. After splicing original connector it worked well. Let’s see how long it lasts.

Fans

Basically runs just above a whisper; if youre more than eight inches from this thing, you dont know its spinning because its just not making any sound at all. Comes with a lot of adapters and such, probably spikes the price higher than it should be, but Im certainly satisfied with the reduction in RPM noise

As usual, an excellent Noctua product.

This is a very quite little fan that move a good amount of air. I bought it for a raspberry pi 3b and a case. I had to modify it a bit to connect to the pi but that isnt an issue with the fan since it isnt made specifically for it. The fan was packed in a shipping box that was the right size unlike some fans that come in boxes that would hold a dozen fans and are stuffed with packing paper.

But expensive, when I get a big old 120mm/140mm for the same or a couple dollars more. The push on this is incredible for such a small fan. Compared to the one it replaced it is a wind storm.

I wasnt sure the built-in fan on my Lulzbot Mini 2 3D printer was working properly anymore (filament was melting sometimes in the area where it shouldnt), so I got this as a replacement. Its somewhat quieter than the original, and appears to be more effective as the problem I was having has since gone away. I was also impressed by the packaging and included materials - good value for the money.

Looks like a nice fan. I accidentally bought the 5v fan when I needed a 12v fan. I am sure it works fine, but I have not tested it.

Great as usually

Fantastic quality. Very silent and the airflow is great. Got it to cool my RaspberryPI3 boards. The accessories and packaging are a work of art. Recommended.
