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

As expected, premium quality. Low noise. Way quieter than the fan came with raspberry pi 4 Cana Kit. Perfect for my mini raspberry pi 4 home server.

Great little fans. Excellent quality. It includes everything you need to install. Also, very quiet. Cant even tell if theyre on.

I used this to repair a fan in an old ClearOne XAP 800. It worked beautifully without making a lot of noise. The installation kit was very complete and i didnt worry a bit about it possibly not being able to connect. It has been running non-stop now for a month or so with no signs of slowing down.

GREAT mounting options, QUIET, and should last a LONG time. You get what you pay for has never been truer, and Noctua fans rock(quietly) !

I dont usually write reviews, but this item has really surprised me. I replaced the very loud fan in my Lorex DV708-D surveillance DVR with this Noctua fan. The Noctua fan is nearly silent. It is packaged very well and has many connection pieces. Ive had the fan installed for about 1 month and there are no issues. I would definitely buy again.

Though small, this fan upholds Nocuta’s reputation. It’s very well made, virtually silent, and moves a decent amount of air for its size. I’m running it at 3.3V without issue

Works with no issues. Very quiet.

Works great, as one would expect from Noctua fans, though it was a bit painful to spend $14 on a single 40mm fan. For my application, the attached 3-Pin connector was way longer than it needed to be. In future versions, Noctua might want to consider putting a quick-disconnect near/on the fan to allow users to choose which cable they want to connect (the 2-pin or 3-pin) without ending up with 6in of extra wire.

Amazing fan. Saved me a bunch of time and money as its easy to install.

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