Very good cooling fan. Multiple speeds. Good airflow. Very very quiet to silent!
The AC Infinity 120mm fan is a solid & quiet cooling fan. I needed something to place either near or on top of my Firewalla Gold as it gets very hot at times and I wanted to see if something could be done to cool it down with zero noise. For $14 I decided to give this well-reviewed cooling fan a shot.Long story short, this fan works flawlessly. It checks all the boxes. Silent running. Multiple speeds (I keep mine on the lowest as that is all that is required to bring the Firewalla cooling fins down to room temp or lower). Inexpensive. I have a router right next to the Firewalla so just used the USB from that for power but any USB type A will do.I also purchased their 80mm dual fans as well and using those on a Comcast Cable X1 box that gets hot in my entertainment center. These help move the hot air out of the semi-enclosed space the box is in.

Quiet fan
Quiet fan. It is a computer case fan but has big rubber feet on both side and all 4 corners. The power cable is usb-a and has another inline usb-a port to plug another device in and these have a switch to change the speed- low, medium, high. I am using this for my cable modem cooling. I had to replace my old modem due to failure and I did notice how hot it got so I am going to keep my new one cooler.

Very quiet and well build fan. I would have given it 5 stars but the shipping (DHL Express to Costa Rica) was horrible

Running Constantly for Two Years
Very good fan. I use it to keep my Android box for my tv cool. This is the second one I've ordered. The other one has been running constantly for at least two years and still works great. My Android box sits right on top of the fan. AAA+++

A quiet fan with low noise levels and built in speed control
This is a solid fan with great value. At high it moves a decent amount of air, and on low it's nearly silent from more than 2 feet awayPutting power draw numbers here for other people's reference:High: .215 amps = 1.075 WMedium: .169 amps = .845 WLow: 0.139 amps = 0.695W
