This is USB powered but there is a dual 1200mm fan AC version , same company for a few bucks more. **Q: Can these be powered by an external battery pack?** A: Yes you can power them using an external USB battery pack (power bank). I have the two fans plugged into a USB power bank, with the adjustable inline switch on "H" High, and they draw approximately 0.45A or ~2.25W total. In theory a 10,000 mAh power bank can run these two fans on high for ~ 20 hours. **Q: What is the cord length between the fans please? Thanks...** A: Seems to be approximately 30 inches. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Reduced the temperatures on my router from 92c to 64c. *by on Reviewed in the United States July 26, 2021* Our home has a Linksys WRT32X wireless router which is passively cooled, meaning that there is only a large heatsink without a cooling fan. While this is great for absolute silence, it does affect temperatures quite a bit. I have installed OpenWRT on the WRT32X for more control and features over the router and this includes temperature monitoring. On idle, the router stays at 92c in an ambient of 30. Take note, the router is placed in the open in the TV console, so it's not like it is closed up in a cabinet with zero ventilation. On maximum load tests, it can reach a maximum of around 110c (!!). Temperatures like this would significantly affect the lifespan of electronics so I am compelled to do something about it.Here is where I decided to get these cooling fans to help reduce temperatures to more sensible levels. I wasn't expecting what a difference it could make. I simply placed the fan on the top of the router where it sucks out the hot air from the router. Idle temperatures dropped from 92c to 64c. You can take a look at the temperature graph I have included. You can see when I plugged it in and the temperatures starting to decline gradually. I tried reversing the orientation of the fan such that it blows cool air into the router instead of sucking hot air out of it, but there didn't seem to be much difference, so I just let it suck the hot air out.The fans themselves are very easy to use. It is powered by a USB port, and the router conveniently has a USB port that I'm not using otherwise, so I plugged in the fan there. There is also an inline speed controller that allows you to set it to off, low, medium and high. I noticed that if I set it on low, the controller gets just a little warm, while on high it is cool. I'm guessing there's some kind of resistor in there that reduces the speed of the fan by diverting some of the electrical power to heat instead. Speaking of the fan speed, even on the high setting, it is still fairly quiet and moves a generous amount of air per fan. The fans come in a set of two, so I'm using one for the router, and the other for general ventilation to keep air moving around. The fans themselves have rubber feet and a metal grating in front to prevent accidental contact with the fan blades. The rubber feet also provids some distance between the fan and the device it is cooling so that air can pass through more easily.Overall, this is a really good buy and helps so much in keeping our electronics cool and extending their life. ### ⭐⭐⭐⭐⭐ really “cool” cabinet fan system - highly reccommend *by on Reviewed in the United States January 29, 2017* This is a really “cool” cabinet fan system. We have a custom built-in entertainment cabinet in our family room. The top section has the flat screen LCD TV with the Wii equipment and the middle section has an audio system, TiVo, CD player and a VCR, (I know why a VCR). The new TiVo and the 25-year old audio system generate a fair amount of combined heat that I wanted to remove. I did a search on Amazon for cooling fans and looked at several options. Having a system that was temperature controlled and could adjust the speed of the fans was very attractive so I decided to focus on that solution and was very impressed with the features of the AC Infinity products. I ordered the AC Infinity AI-ATC, Fan Thermostat and Speed Controller, MULTIFAN S7, Quiet Dual 120mm USB Fan, and MULTIFAN S5, Quiet Dual 80mm USB Fan. Everything arrived in two days; the three items were well packed and arrived safely.Now I could actually see and test what I got and found they were even better than I had expected. The controller is a perfect size and flush mounts in my equipment cabinet. The temperature probe has a long enough wire to run it down and over to place on the audio amp and under the TiVo where the maximum heat is generated. The fans have large rubber grommets on each corner to stand on or mount with and no vibration is transmitted through. One set of fans are in the equipment section behind the equipment blowing air out through the equipment towards the open room. The second set is located in the TV section also blowing from inside through the TV towards the room. Running at full speed in a quiet room you can of course hear the mechanical fan and wind noise. However, when the audio is on, even at a comfortably low, watch the news level, the fan sound level drops below the audio program level and is no longer discernable. With the controller running in the “smart” mode the fan speed is reduced when the equipment temperature is within two-degrees (or four) of the desired set temperature. As they say on TV “Just set it and forget it”, the controller keeps the fans running as long as the equipment is generating heat above the set point. When the audio amp is turned off and the TiVo goes into stand-by the fans cool them down and then shut off. When I am able to locate my hole cutting drill I will add some ventilating holes in the top of the cabinet and between the sections in order to improve the circulation of fresh cooler air into the cabinet to improve the efficiency.I am so pleased with this cooling solution that I am ordering another setup for our weekend summer cottage up north at the lake. Again, there is an audio system but in addition there is a Magic Jack phone module and the cable modem / WiFi router generating heat. They are in a confined space that gets hot so I had placed a small fan in there to circulate the air. When we are there, I plug in the Magic Jack and turn on the fan. Now I will be able to automate the cooling.If you are looking for a great way to cool down your expensive equipment this is an inexpensive solution that I highly recommend. ### ⭐⭐⭐⭐⭐ PRO tips for the PS4 PRO *by on Reviewed in the United States August 27, 2018* These fans are great for ensuring circulation, cooling, and minimizing fan noise for your PS4.I’ll list some PRO TIPS below (pun intended).READ BELOW FOR THE TIPS.Though it’s completely normal for your PS4 to get medium-hot, it never hurts to maximize cooling for any electronic... ESPECIALLY in enclosed places.When the system is cooler, the internal fan don’t need to work as hard, maximizing efficiency and naturally prolonging the life expectancy and overall reducing its noise.These fans are super quiet and by keeping the system cool, the internal fans don’t need to work half as hard, thus reducing overall noise significantly... Which is a great bonus.With these fans on high setting, placed like in my photos, my PS4 never exceeds a mild warmth.These fans are versatile, allowing you to link more fans if you’d like, and allowing you to set them up however you’d like depending on your setting.NOW FOR THE TIPS:1. Do this first!You’re probably aiming to reduce noise and/or keep the system as cool as possible, so I’d HIGHLY recommend to begin by dusting out the internal fan just for the added benefit. It’s very simple with the PS4 PRO. Simply pop off the top cover and air dust or lightly wipe off the fans and place the cover back in. (Refer to how-to videos online). This’ll keep the internal fans running efficiently.2. USB tips:(1). There is a hidden USB port in the BACK of the PS4 PRO use that one to keep it out of the way and to leave your front two USB ports free.(It can turn on and off with your PS4)(2). You’re likely using a 4K TV or any TV with many ports these days, so chances are you have a USB port in the back of your TV, that is another convienent option for you. I use this option.(It can turn on and off with your TV)(3). You can simply use an adapter to plug into the wall, but you’ll have to remember to turn it off and on manually.3. Fan placements:(The side that blows out is the side where the wire is visible)The placements I personally recommend and use myself (pictured) is one fan on the bottom holding up the PS4, blowing UP onto the bottom of the PS4 and one fan sitting on top blowing DOWN onto the PS4.Creating an external fan sandwich.Having the PS4 lifted will also allow the bottom to get some proper air flow.(I found a foam and plastic piece that I placed under the front of the PS4 as well, just to make sure the PS4 sits comfortably & with better balance.. I’d recommend something like that too).Side note: if you’re gonna set it up like this, put something under the feet of the fans if you’re placing it on wood.. Otherwise, it could leave light rings in the wood from the pressure.Alternative placements:(1). You can sit up one of the fans so it blows right into the vents on the right side of the PS4, this’ll help get cold air into your PS4. Not a bad option.(2). You can also sit up a fan at the back of the PS4 (where air escapes from the system), blowing air AWAY from the PS4 - helping suck the air out.But honestly, i think the other methods are more effective. I’d probably only recommend this one if your PS4 is in an enclosed area and you want to help the hot air escape from the area (like fan cutouts at the back of your enclosed area). Otherwise, the other methods work better in my experience.If you found this review helpful, please thumbs up this review!
