AC InfinityMULTIFAN 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.

The media could not be loaded. 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!

I got these for my Denon AVR, they run really hot. I had to send one of to be reset by Denon factory as it had gotten too hot. These bad boys don’t allow any heat to sit in the unit. I can run the AVR all day with the pair of of fans sat on top, on the low setting and you can feel any heat. All the gripes about the fans being loud is pish! If your watching films or playing games and you can hear the fans, then you haven’t got the volume on! Sure put the fans on high and you hear it enough to ruin a film but you don’t need it on that setting, they work so well, I have them on low and it’s smooth and quiet and keeps my AVR cool 👍🏻

There's fans do what I want them to do, the packaging was a lot better than I was expecting, really well presented.The fans are quiet, but there is an electrical buzzing noise which drives me slightly crazy, considering the price I don't think its fair to complain too much, it does what I want it to do well. I have a computer in not very well ventilated area and heat was building up when under heavy loads for prolonged periods, these fans do help surprisingly well even on the lowest setting just to shift the air away. If you are near the fans or fussy about noise levels I wouldn't recommend it, I can live with it on the lowest setting though, and I've started using headphones more often which prevents me hearing it too!If your using these for something over a metre away from you I'd have no hesitation to recommend them, if you sit near them they may annoy you depending on ambient noise around. I like to work in silence so I tend to turn them off when concentrating.

I have a tv cabinet that is wall-mounted and a panel door that keeps it shut from IKEA. Looks good but terribly designed in letting my consoles vent. I manually cut vents into the sides and fitted a metal grill to cover my handiwork but the heat was still trapped to a large extent and I was worried my consoles would just burn out as it's on for most of the day (for gaming as well as streaming tv).These vents are very well built, not cheap plastic, and very easy to install. Operates very quietly and smoothly and turns on with my xbox which is all I need. Huge difference and immediate improvement as I had them facing the grills and now it just pulls and expels the hot air out. Life saver for my consoles and should have got these sooner!
