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

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

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.

Extremely loud.

What else is there to say. It is a Noctua fan so it works perfectly and is basically silent.

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

Awesome cooling fan. Works great with ODROID C2, brought temps down from 69C to 32C. Extremely quiet and has a good airflow. Definitely worth the money.

replace noisy fan on my home surveillance DVR. Made such a difference in noise level!

Good works good with reolink cameras nvr

Nice little fan. Using it to keep my raspberry pi cool and it does a great job at doing it.

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.
