AC InfinityMULTIFAN S3, Quiet 120mm USB Fan, UL-Certified for Receiver DVR PlayStation Xbox Computer Cabinet Cooling

The fan came fast and was packaged well. It was easy to use, simply connect the usb to power. It has 3 settings, low, medium and high. Even on the lowest setting it moves the air and cools noticeably. This fan is quiet even on the highest setting. It came ready to be daisy chained so a second fan would be simple to connect. It can stand on its own and can be positioned a multitude of ways while remaining operational. It consumes very little power. I have connected it to my power bank and it goes well over a day before I have to think and recharging my power bank. I am happy with my purchase and I plan on purchasing a second one.

Modem regularly overheated on a poorly ventilated shelf - until purchase of this fan. Quiet, reliable, and effective - solved my concerns about heat-induced reliability issues or shelf damage. Device is practically cool to the touch, now. However, I put it on the bottom, not the top like the illustrations. But I'm sure both work.

I bought a few of these and run them 24/7 for many months, they do outstanding job at pulling low watts and keeping devices cool (apple tv, routers, etc..). They are easy to mount and the air volume is impressive. Quality stuff and feel these will last for many many years without an issue. Glad I bought.

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.

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

Exelente calidad muy buena recomendado

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 reasonably powerful fan. Does a great job cooling my optical drive during disc rips.
