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

Added to a raspberry pi 4 Kodi box. I cant even hear it over the normal room noise even sitting right beside it.

Using this with a Raspberry Pi 4 in an aluminum case.

Im tempted to deduct one star but not of the fan itself. The packaging and accessories packed with it make me feel Im paying way too much. I only need the fan.

Perfect replacement fan for an old Dreamcast (requires 3D printed adapter). Wires are really long and I was impressed with the packaging and hardware/adapters that were included even though I didn’t need them in my case.

Before now, Ive only heard from others about how quiet Noctuas legendary fans are but actually hearing them for myself is really something else... maybe its because the fan I replaced was much noiser, but its mind-blowing how silent they were able to make these fans!

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).

When it outputs air from the Raspberry PI 3 its very noisy. When I flip it to blow air into the case its much better. OK I guess.

I use them on my Pi 3 to keep it cool, works great and quiet.

Best fan available on the market. I purchased the cheaper China built fan and it died after 6 months. This fan (Tiawan) is solid, quiet, and a great buy with all the extra accessories. You get what you pay for!!!! I needed the 5v version for a Dauha NVR Security Camera system. With the added cords, I was able to adapt the default 3 wire cord to attach to the 2 prong motherboard connection. I really like the rubber mounts on the fan. Very quiet and moves a good amount of air. The china built fan was very loud. I would buy this again. Its worth every penny.

Works Great
