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

Piece of JUNK product screw that came with the product did not fit. when you try to contact customer Service from Noctua good luck getting any support. JUNK GARBAGE product and never again.

first time Ive used Noctua fan for a Raspberry Pi4. Im blown away, no pun intended. I replaced a chepo pi-fan came with a pi case. I can hardly hear it. Would buy again.

I normally would not write a review about a case fan but this fan is amazing. The quality is the best I have seen in a small fan. Most small fans are of course made in China but this is made in Austria and while it may be ugly (brown) I dont care.

I put this on my raspberry pi case. I used a dremel tool to create a bit more space for it, but it provides plenty of cooling so I can use it as an HTPC and server for my plex server. Very happy with it.

What a fan, I bought this for my ODroid and I couldn’t be happier. The plugs it comes with are not correct for the odroid, but I stole the plug from an old cMOS battery and Im off to the races.

perfect fan for my raspberry pi case. Super quiet and keeps my pi cool.

Quiet and moves the air... bought it to replace a underpowered fan on my 3d printer.

Amazing little air mover that can add life to small electronics. Its slim at 10mm which makes it great for many applications where the bulky and more common 20mm thick fans will not fit. In fact its so slim a surface mount would be acceptable in many cases. I do wish that it came in different colors though.

I usually pay a little extra for Noctua fans for my computers. They always outlast the computer that they are installed in. Ive bought two of these 5v 40mm fans to use on Raspberry pis now and I really like them. They are quiet, push plenty of air, and I know they will last a long time. Some people think the color is ugly. I dont mind the color, I actually kind of like it.

If youre looking for the fan needed to retrofit into a VA1 or 2 Sega Dreamcast, this is what you want. It just requires a couple of 3D printed parts and a wire adapter you can get for about $12usd along with this fan. Turns a somewhat quiet DC into a nearly silent one. Highly recommend to use Noctua over anything else. The quality of it sets the standard everyone else should be following.
