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

Slightly more cost than a cheap Chinese brand variant you find at neighborhood electronics store; this fan delivers on quality and reliability. You can tell as soon as you fire it up, its extremely quiet and moves volumes more air than the last unit. I installed onto my security camera DVR and couldnt be happier. I recommend this unit to anyone looking to replace a similar fan. This unit has several connector tips for different applications.

works well with my Lorex camera system

didnt cool my cpu in my lorex security DVR. Nice fan just didnt do what I needed...Had to buy OEM replacement.

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

I use these on my Raspberry Pi 3 and 4. The fans work well as simple, effective cooling solutions.

Ive had bad luck with these tiny fans. This one is an exception. Very quiet, good construction. The wiring is very stout. I was impressed with both the packaging and the materials used. Im very happy with this purchase!

I bought and tested a few 5v fans. The Noctua fan outperforms them all by ~20 degrees Celcius. The build quality is incredible and the soft silicone corner mounting points and fully sleeved cables are a plusses. I was able to use two of the included barbed rubber mounting rods instead of screws.

Our fan broke in our receiver. This worked perfect. The fan is quiet.

In order to fit this into your Dreamcast you have to buy a 3D printed fan mount adapter and wire adapter. It works great, and is much more silent than the original fan inside. My heavily modded DC stays nice and cool, and super quiet. Love it!

Basically runs just above a whisper; if youre more than eight inches from this thing, you dont know its spinning because its just not making any sound at all. Comes with a lot of adapters and such, probably spikes the price higher than it should be, but Im certainly satisfied with the reduction in RPM noise
