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

The old fan on my Lorex was so loud right out of the box. I have had this one installed for a few months and it is still quiet, plus I can tell it has much more air flow.

Very impressive!

no complaints

used this for my Rasp pi 3 that put under heavy load frequently. before it averaged 45-50C and now never really reaches 46. 10/10 recommend buying this.

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.

Great fans!! They come with a bunch of extra goodies which is a plus. I used mine for a solar charger project.

Another excellent Noctua fan! After seeing the need to cool my Raspberry Pi 4, I snapped up this a4x10. After drilling holes into the case, I’ve mounted the fan and am hitting sub 30°c on 5v on the Pi, running Pi-Hole.

Running this on top of an aftermarket heatsink (https://smile.amazon.com/dp/B00ZRDRX8M/) on an ODroid-XU4. Its quiet and blows just enough air to keep the CPU from throttling under even extreme loads (8 cpuburn processes).

FYI: Buyers check your fans before trying to install. I ordered a 5v fan, it arrived in a box labeled 5v. Tried to install and get to work and had problems. Had 2 fans for 2 applications so I tried the 2nd fan, same problem... I then looked and realized that the fans were 12v fans. So Manufacturer either installed wrong fan in box or mis-lableled the box.... Dont know how many more are out there but 2/2 I ordered were that way.

Every time I dont buy a Noctua fan I regret it and end up buying one anyway so this time I decided to save the disappointment of a cheap fan and bought one of these to cool my small Minecraft server running on a Rock Pi 4c. When air cooling with a heat sink on all large surfaces, temperatures were around 50C at idle and have peaked above 80C with multiple players online. The fan and heatsink combo easily keeps the idle temperature at around 35C and I havent seen it reach even 60C on max load. A case optimally designed for cooling would probably achieve lower temperatures. Im running this at 5V and cant hear it at all given the computers positions. If youre looking to cool any SBC, get this fan and you will not regret it.
