AC Infinity MULTIFAN S5, Quiet Dual 80mm USB Fan, UL-Certified for Receiver DVR Playstation Xbox Computer Cabinet Cooling

These fans come really nicely packaged, good instruction booklet, and feel very professional. The grills look great and have a nice professional logo on. The variable speed is great - on the low setting they are silent, and barely audible on medium. on Hi you can here a feint whir if you are near, but if they are in a AV cupboard you won't notice. They shift a fair bit of air given the low USB power. I wanted a couple of fans to use on a Biltong drying box I was making. these fitted the bill perfectly. Powered by a USB wall wart I had lying around, one fan blowing in, one fan extracting, with variable flow. I removed the grills and rubber feet which are easy to do, and had to fit a different air filter, which is a shame given the nice appearance of the fans! They fill my purpose spot on, and I would highly recommend them as they are good value and nicely made/packaged.

I am using these little 80mm fans pointing towards the vent on my solar generator. The fresh air helps with the cooling of my Ecoflow along with its built-in temperature-controlled internal fans. The two in this set use about 2 or 3 watts all together when on middle setting plugged into the usb port on my Ecoflow. Low setting doesn't use hardly any wattage but in my opinion isn't powerful enough for my needs. As for noise, they have bumpers on the corners to lower vibrations, and fans rotate super smoothly with no jerking. On the lower setting I can barely hear them. On the high setting only a quiet hum which I personally don't find intrusive...my other half who's super sensitive wasn't keen on top setting - however as everything will be ultimately mounted out of the way won't be a problem. If you watch my video you can hear the click when I change settings up and then down, suggest you turn up your speakers if you want an idea of the sound these make while running :) There's a toggle switch for Off, Low, Medium & High settings, with the cable long enough that I can put the fans behind my unit and have the switch around front for accessibility which is handy. On medium setting my Ecoflow isn't running its internal fans so often which is great as I know there's not too much build up of heat, better for longevity. They also run quieter than the internal one. As these are small in size they are not super powerful but used only a few inches away from the vents in my Ecoflow they are perfect for my needs. Hope this review helps those of you thinking about purchasing!

I'm very impressed with the quality of this product. It is very carefully packaged, albeit in plain cardboard, in a way that indicates a lot of thought has gone into this product from start to finish. The rubber feet work really well. The fans are smooth and quiet (but not silent - you can hear the air moving, for sure, but it's low volume). Connected to a Playstation 4 Pro, these keep the device cool in the cabinet and no noisy Playstation fans need to kick in, I have found. I might buy some more to have on my desk this summer, actually as my 6" desk fan sounds like a jumbo jet. By way of experimentation, they also worked plugged into a Panasonic TV and my laptop, as expected. I think the killer feature with these is the rubber feet, top and bottom. They work so well!

Pretty decent and well built, less powerful than expecting but seem to create cool air Using on Xbox One X as it's in a TV cabinet with restricted space it can overheat when being used on hot days for long periods of time especially in 4K games and those using lots of the GPU. (COD:Modern Warfare etc). Seem to be doing the trick so far, I have one positioned on the left of the console to push cool air in and one on the right side near the back to blow air out. They are on high speed. I have a Kinect plugged in th back of the console but when piggy backing through the fans it will not work so its plugged in the front where my play and charge lead is.

These are such underrated fans, using them as extractors from my ps5 that burns in a cupboard, there's not much heat in there anymore even during heavy gaming sessions. Lightweight and quiet even on the highest setting too, a Godsend

Great fans, nice price.

So far, hugely impressed -- I've set these up on a rather cobbled-together frame, blowing cool air at the underside of my MacBook Pro, which was running very hot a lot of the time (REALLY bad for Lithium Ion batteries), and it has made a huge difference. The fans themselves are quiet, and the feet complete the job -- I can barely hear these fans even though they're pretty close to me, on top of my desk. The one thing I would say is -- if you have sensitive devices (external displays, hard disks) on our USB bus, switch off the fans using the inline switch BEFORE you unplug them. They draw quite a lot of power, and the jolt if I just unplug them is enough to crash my displays, which in turn crashes the machine. But as long as I switch them off THEN unplug, it's fine. I've actually just ordered a high power USB PSU so I can plug them straight into the wall instead of running them off my USB hub, at which point it won't be an issue anyway. I don't often give 5 star reviews, but I'm very happy indeed with these (and they arrived the very next day, despite the covid delays, though I may have just been lucky!) -- and should anything change, I'll come back and edit ;)

I have these on top of my new Marantz Amp because it's a slim model it get quite hot so these are a great way to keep it cool. I have one blowing air down on the power supply and the other taking the hot air up and out. They have a switch for the speed of the fan low,medium and high, low speed is very quiet the medium is quiet too but on high you can hear it on low volume tv or in between adverts when it's quiet. I set it to medium and on low volume tv or bluray or cd you cannot hear it at all. Before I bought these my amp got very hot after a few hours on a night but now with the fans on medium it's cut the heat down by half, Iv always said if an electronic product like an amp or laptop runs hot it won't be long before you start having problems with it.

perfette! molto silenziose ed utilissime per raffreddare pc, laptop ed altre superfici che scaldano molto. le tre velocita' sono un must! superconsigliato

I bought these to cool my amplifier down in the summer time. Works perfectly. No wind noise from them at all! And they do a good job. Buy buy buy if you have a over heating problem in your amplifier. The only negative things are that the cord is quite stiff. And long. Otherwise perfect.

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.

Very efficient and quality product

寝室にあるルーターを冷やすのに使っています。 存在を忘れるくらい静かで、私は気になりません。 ルーターもしっかり冷えます。 買って良かったです。
