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

FYI: Buyers check your fans before trying to install. I ordered a 5v fan, it arrived in a box labeled 5v. Tried to install and get to work and had problems. Had 2 fans for 2 applications so I tried the 2nd fan, same problem... I then looked and realized that the fans were 12v fans. So Manufacturer either installed wrong fan in box or mis-lableled the box.... Dont know how many more are out there but 2/2 I ordered were that way.

Very Happy with this fan, quieted my DVR to near silent!

Works with no issues. Very quiet.

Not much to say about it. Its a Noctua fan. Quality is always great, its nice and quiet, not a big fan of the color but my case doesnt have a window so Im not upset about it. I dont think Ive ever regretted buying a noctua fan.

great little fan I cant even hear it run!

As usual, an excellent Noctua product.

Moves a good amount of air for such a small fan, and makes MUCH less noise than the cheap fan it replaced. This 5V fan is great for cooling a Raspberry Pi3 or ASUS Tinker Board.

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 really like this. The noise level is much better after I change my fan to this one.

Fantastic quality. Very silent and the airflow is great. Got it to cool my RaspberryPI3 boards. The accessories and packaging are a work of art. Recommended.
