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

This was an addition to my Pi 3, dilivery was fast. The fan fits in the case very well ans runs very quiet. It comes with rubber attachments that reduse noise.

Im using the NF-A4x10 5v fans in 3D printed Raspberry Pi cases to house my Pi 4 units. The fan is really quiet but pushes plenty of air to help keep the CPU and board cool on the Pi. The fan can be driven directly off the PIs PGIO pins. However, I also recommend a grille/guard - either a wire one you buy or a 3D printed one - to keep your fingers safe when its running.

I have a heatsink for my raspberry pi that I picked up that was both noisy AND annoying as it had LEDs on the fan. Swapped it out with this fan and, while I see it spining, from a distance I hear nothing! absolutely quiet AND I am running my Pi4 24/7 at 34.56 C / 94.2 F... had to take the heatsink off to make sure the sensor was working!

What a fan, I bought this for my ODroid and I couldn’t be happier. The plugs it comes with are not correct for the odroid, but I stole the plug from an old cMOS battery and Im off to the races.

Fits my 3d printed case perfect, also tested with market cases - fits in all standard Pi size cases.

Works great and is extremely quiet, at least compared to what was in my Q-See surveillance nvr (I replaced the cpu fan in the nvr). Wasnt a perfect replacement for the nvr fan, but I was able to use the included with fan rubber mounts/insulators to install over the cpu.

This is a trooper for my wierd home plexus server pineboard build in an old Compaq chassis... lol love it!

I replaced the stock fan from the MISTER i/o board.

Bought this fan to replace the noisy fan inside the Lorex HD surveillance system I bought from Costco about 4 years ago. Reached out to Lorex support was pointless and a waste of time for a replacement fan from them. Instead, I bought this fan. It is easy to install:

Used for an old AMD modder trick. Mounted to the backside of the motherboard blowing on the bottom of the cpu socket to reduce the cpu temps.
