AC Infinity MULTIFAN S5, Quiet Dual 80mm USB Fan, UL-Certified

These are amazing little fans. Compact, whisper quiet, do exactly what they are designed to do. I originally wanted to buy slightly bigger versions and was concerned these wouldn't be strong enough, but they keep a 4-disk RAID and 2 other spinning disks cool, even on the lowest setting. On very hot days (e.g. 36°), I raise the speed from low to medium and that's enough to keep everything cool. Highly recommended.

With my PS4 in an IKEA unit ventilation has been a perpetual issue. I've even tried keeping the back of the unit facing outwards but with the new power supply on the PS4 Pro coming loose when you move the unit I needed a permanent solution that didn't require new units or major drilling of holes. For a low price I thought I'd give this unit a shot and so far I am more than impressed. Keeping it on Low or Medium my PS4 is now cool to the touch with one fan at the rear of the unit moving the air away and the other fan on top where it used to get hot. Even my wife with super hearing can't hear these two fans running when I'm playing now, and powered from the USB of the PS4 they just turn off and on with the console (check your settings to turn USB power off on standby). Definitely recommend this to any gamers with a cooling issue.

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.

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.

Excellent item and well made

Bought them for my cinema amplifier to keep it cool work really well

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 ;)

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

Very good

Price is good, product is working fine. Delivery is quick as well. Speed is adjustable. Nothing to complain about. Love it.

Ventilateur d'aussi bonne qualité que ceux qu'ils copient, à savoir les "Infinity" . mêmes fonctions, même niveau sonore ,même efficacité ; ( Certainement fabriqué au même endroit. )

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.

This fan is very good has a good build quality, looks very good and runs very quietly , performance is also good but only negative cost is very high.
