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

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

I bought this to replace the failing fan in my

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

Very high quality fan. It comes with a wide assortment of adapters and even crimps for custom wiring jobs. It also moves a good amount of air.

This is a fantastic fan to use when modding your dreamcast. I am so pleased with this fan choice. Its super quiet, installs easily (with 3d printed mount) and was simple to rewire to the dreamcast connector.

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.

I see why this brand has a great reputation. The fan is so quiet, I cant hear it. Came with lots of connectors too, but I still had to splice my old one onto the new fan:)

as expected

I wasnt sure the built-in fan on my Lulzbot Mini 2 3D printer was working properly anymore (filament was melting sometimes in the area where it shouldnt), so I got this as a replacement. Its somewhat quieter than the original, and appears to be more effective as the problem I was having has since gone away. I was also impressed by the packaging and included materials - good value for the money.

Always excellent quality fans
