My last cable modem up and died after just one year, I'm pretty sure because it got so hot all the time. It was a modem+router so extra hotty-hot-hotness from all the circuitry packed into one case. My son thinks this is sort of normal lifespan for routers and modems - he expects only 3 to 4 years. Well I got 8 years out of one of my last modems and 10 out of the other (same modem, WTGS54 whatever that was, it was a very good modem for its time and I got more than enough throughput from it for my needs, including streaming video, I was still running one up until 2 years ago). So *I* was shocked at its short lifespan (especially given the cost, over $200) even if he wasn't. There is just more electronics involved in these tasks, packed into less space, than the older modems. They are GOING to get hot. So in order to keep that from happening again I bought this USB fan kit, comes with 2 fans hooked together, to replace the floor fan I had aimed at the new modem and separate router. I was getting some of these anyway to put on my LED grow lights to cool them (they will ALSO last longer if you keep them cool) so I took one of those and shoved it under the router (because its a flat design, give me vertical any day) and stood the other one up next to the cable modem (which is vertical). I've got them on low and they are cooling both devices very well. On low the router gets barely slightly warm, and the better design of the vertical case for the modem leaves it totally cooled down with this little fan. If I had it to do over I'd look harder for a vertical router as well, its easier to keep them cool. AND they take up a lot less space! I've got a bunch of old computer cases with fans going to waste, I will likely make some USB fans from all those old bits and pieces, but they are likely to be a lot louder. This fan is extremely quiet even on high. I can't hear it at all on low. Also these fans in particular are optimized for humid environments so I wouldn't use anything else in my grow room. A lot of people use the other dual fan kit with the larger fans but they are using them to move air over microgreens to cut down on mold and fungi, I don't have that problem, I just need to cool the lights to improve their longevity, so I'm trying these smaller fans (take up less headroom over the lights, giving me more space under the lights because I can move them further up). I highly recommend cooling your router/modem/game console whatever electronic devices you have sitting around generating heat with some kind of fan, and these are very quiet, easy to assemble (as in plug them in), and very effective. I've seen some people insist that you shouldn't do this because it might "blow dust into the case" - where do these guys live, in the middle of death valley? LOL! Just do it. I've had a floor fan blowing across my very very ancient laptop to keep it from overheating for about 5 years now (even laptop coolers can't cool it enough) and its still going strong. I can even play (very very old) games on it still. Heat will kill your devices WAY faster than whatever tiny specks of dust these fans probably won't blow into the cases anyway. Also, if you have one of those stupid refrigerator closet things where they've built an enclosure all the way around the fridge, that is trapping heat and shortening the life of your expensive stainless steel fridge - you can use these fans to draw hot air out of that too (though I'd go with the larger version for that). Personally I'd tear that crap out but failing that, install these in a side or back wall and pull that heat out of there. Your fridge will thank you. Your bank balance will be the better for it over the long haul.

**AC Infinity MULTIFAN S2** I placed this fan on top of my Xbox Series S to help with cooling. It's USB A and comes with a power block, a speed controller and rubber feet. I plugged it in to a WiFi outlet so I can turn it on remotely when I start playing, without having to reach behind the console. Installing it was easy, insert the rubber feet, plug it in, and set the speed. It has three speeds The lowest speed is very quiet and you can barely hear it. I use it on the middle speed, you can hear it if you are listening for it but after a few minutes it fades into the background. I'm not really sure if my Xbox needs it or not, but it does get warm, and it's narrow in my entertainment center. This fan blows the air out sideways, I turned it so it blows out the back where there's room for the heat to dissipate. When I'm using the Xbox, the air coming out of the fan is warm, which means it's functioning as expected. Cool is better than hot, I'll take it. So far so good. I would say it's a good value for the money.

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.
