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.

Very efficient and quality product

I just bought a used Onkyo TX-SR805 receiver already knowing that they run hot from reading reviews. When I arrived home I immediately set it up and liked the sound. Within 30 minutes I put my hand on the top of the receiver and could not believe how hot it was. You could fry an egg on it. I knew this was not good. I then noticed that the side vents, one on each side, housed a fan each. The fans were not working. I believe this is one of the reasons Onkyo has a reputation for very hot receivers, inefficient cooling system. Replacing them would probably not be cost effective. I purchased this set of fans from Amazon and set them up vertically at the rear of the receiver, one on the left and one on the right, to push the air towards the front of the receiver and out of the cabinet (I have an audio visual cabinet with doors. I keep the doors open). This setup produced cooling and the fans were powerful enough to push the air out of the cabinet but the cooling was only fair. I was not satisfied since the receiver top was still hot, though not as hot as before. I now proceeded to lay both fans on the hottest sections of the receiver venting the hot air out of the receiver and was amazed at the results. The receiver cooled down so much that when I touched the top of the receiver I felt no heat. I ran my hand across the top of the fans and I felt the hot air being drawn out completely. By the way the setting I have it on is HIGH. I didn't try medium or low since this receiver produced atomic heat. The receiver remained pretty cool with this second setup. I just purchased another set to stand up at the rear of the receiver (as was my first setup) to push the hot air forward away from the front of the receiver, as I plan to elevate on 4 columns (4 black pepper shakers from Dollartree-perfect size-about 1/8" taller than fans) my turntable. It remains pretty stable. As mentioned previously, I have my audio visual components (8 in total) enclosed in a cabinet with doors. There is an open back and the doors swing out and to the side and back, out of the way, making it perfect for my rig. Will probably update with photos once everything is in place. Definitely recommend these fans. Especially for the price. I was going to buy AC Infinity's more expensive setup with the 3 fans that lays on top of the receiver and vents out the rear but didn't want to spend $119 for it. I read in the reviews that it was a little noisy and that thermostat is inaccurate. Two sets of fans for $30 and 4 black pepper shakers from the Dollar tree (come in a set with salt) for a total of $34 Will actually do a better job because you are using 4 fans this way, which can be Daisy chained compared to only 3 fans with the $119 rig. As a former Marine we are taught to improvise and improvising can save beaucou bucks. Wishing you the best and God bless. UPDATE:. Just received the second set of fans and set them up at the rear of the receiver to push the air out of the front of the cabinet. Fan setting is on high for all the fans. Works marvelously! Haven't purchased the pepper shakers yet from Dollartree (was there today and forgot-set it up earlier with two of the shakers-one salt white and the other pepper black-work perfect!) so I have the turntable set up on empty medicine bottles. Supports the turntable steadily. Bottom of turntable is not hot as air extracted upwards from receiver vents is immediately being forced forward by rear fans and forced out of the front of the cabinet. These fans are GREATTT! I can feel the hot air being pushed out the front when I stand in front of the cabinet. Feels like a furnace is on. Really glad I found these on Amazon because this is really a great receiver and was concerned that it would sizzle out on me. Now I have to figure out how to hide the wiring on the floor. Pictures enclosed for viewing fan setup and turntable elevation. Wishing you all the best.

working well for about 6 months now. very quiet. use it to remove hot air from AV system. only crib is that the wire is kind of thick and long. it may be a blessing for others who need to run the wire longer. I use a dedicated usb power supply (1mA) to power it. dont want to load the USB port of my receiver all the time.
