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

Was looking for a fan to keep my raspberry pi cooler while I have it mounted on to a ender 3 3D printer and it does pretty good, even with it being in inside a enclosure tent for the printer.

Quiet and gets the job done.

I bought this to replace the exhaust fan in my Sega Dreamcast. I love how quiet it is with its definitely superior cooling power. Comes with a variety of connectors for whatever project you have.

Day and night difference. When compared to the factory fan of my security system DVR, this fan wins by a landslide. The install was very easy, though I had to break of one of the plastic pins in the original connector to make the adaptor for the fan fit (no big deal). The product could take it one step further and provide a couple of small zip ties to make the job clean. Overall I am satisfied with this product and would recommend it to others looking for a quitter alternative to factory loud fans. Of last note, please do not expect to not hear the fan because you still will, however, it will be much quieter that the factory fan (at least this was my experience).

I purchased 3, 2 worked great. Third one out the package did not work

Great product

Bought one of these for my raspi setup and it works great. Super quiet and efficient, keeping the board from 50°C-60°C(with heat sinks alone) to 30°C-35°C. Im tempted to buy Noctua fans to replace my 3D printers fans.

I used this fan to replace a ARX Cera Dyna FD0540-A3212A fan in my ADT DVR. The Cera Dyna was way louder. It eventually started to wobble and then it totally failed. The Noctua was a direct fit and super easy to install. Everything I needed was included in the kit. The only tools I needed were a pair of pliers and a Phillips screw driver. If I could rate this thing 10 stars, then I would. Im super happy.

As described

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.
