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

Using these on raspberry pi’s and the included wire connectors let me connect it up with Pi’s gpio pretty easily. Very handy to have when using poe hats that don’t have their own cooling, there’s enough airflow to keep everything cool. Will keep buying !

Purchased for my Pi4 works great. Very quite. Keeps it cool with heat sinks installed.

Good wind. Low sound. Thats what you want... Thats why youre upgrading a fan. One of those 2 reasons is why other fans have proved to be pure trash. Worth every penny on my DNS 320

Purchased to mod an Odroid Xu4q. Fan is high quality, packing is excessive, and the noise level is low as advertised. None of the included cables are helpful for this application. Throw them away and pick up a pack of JST 1.25mm 2 Pin Micro Male Cables (https://www.amazon.com/dp/B013JRWCBU/ref=cm_sw_r_cp_apa_i_5n9mDbB72NPPV) then splice a male adapter directly into the cable attached to the fan upon open. This will require minor soldering but yields the cleanest result.

Awesome little fan. In case anyone is wondering, Yes it works with the gpio pins(5v and ground) on raspberry pis(well the pi2 anyway) small enough to fit in almost any size project. Moves a surprising amount of air for such a small fan. I may get another though I only have 1 ground for 2x 5v and 1x 3.3v thats close by.

Im using this to cool a raspberry pi 4,the fan works great, the only downside was the amount of cable that was there. Fitting all that cable(with the 3-2pin converter) into even a large case was not easy and definitely will block some airflow.

I usually pay a little extra for Noctua fans for my computers. They always outlast the computer that they are installed in. Ive bought two of these 5v 40mm fans to use on Raspberry pis now and I really like them. They are quiet, push plenty of air, and I know they will last a long time. Some people think the color is ugly. I dont mind the color, I actually kind of like it.

It’s pretty quiet and blows pretty hard, I used it on a raspberry pi and My temps are about half of what they are with no fan

I put this on my raspberry pi case. I used a dremel tool to create a bit more space for it, but it provides plenty of cooling so I can use it as an HTPC and server for my plex server. Very happy with it.

Added to help silence a DVR Security camera by replacing the old noisy ones. Well worth the purchase!
