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.

Excellent item and well made

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!

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.

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

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.

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.

Der Titel sagt schon alles: Perfekte Belüftung für die PS4 Pro ein einem Lowboard Fach. Ohne Extra Lüfter entsteht natürlich schnell Stauhitze in dem schmalen Fach und das tut der PS4 natürlich nicht gut und da leisten diese Doppellüfter perfekte Abhilfe! Gleich vorweg, man kann sie stehend oder liegend betreiben und jeweils natürlich auch saugend oder pustend. In Verbindung mit einem sehr flachen Laptop Kühlpad (https://www.amazon.de/dp/B01B34928M/ref=pdp_new_dp_review) wo die PS4 drauf steht und diesen beiden Lüftern (einer links, einer rechts an der hinteren Ecke der PS4) bleibt die Konsole angenehm temperiert und Stauhitze wird effektiv verhindert, da genügend davon aus dem Lowboard Fach hinaus geblasen wird. Sehr schön ist, dass man sie in der Geschwindigkeit regeln kann. Achtung Hinweis! Ein Vor- oder auch Nachteil der Steuerung ist, dass der durchgeschliffene USB Ausgang mitgeregelt wird. Schließt man z.B das Kühlpad an diesem Ausgang an und regelt die zwei Lüfter runter, wird auch das Pad langsamer. Kann ein Vorteil sein, wenn man nicht ganz auf Lüfter verzichten möchte, aber diese so leise wie möglich sein sollen, dann lässt sich das Pad mit regeln. Ich habe es anders herum angeschlossen, also erst das Pad (dieses schleift USB auch durch) und daran dann die Lüfter, da ich durch das Lowboad und den Hitzestau eh die Lüfter immer auf höchster Stufe laufen haben will. Laut sind sie aber auch dann nicht wirklich! Sicherlich, man hört die Lüfter, auf mittlerer Stufe sind sie etwa so laut wie das Kühlpad und und wenn man keinerlei Geräusche im Wohnzimmer hat, nimmt man ein leises Rauschen wahr, nicht viel lauter als das CD Laufwerk der PS4. Sind die Lüfter auf höhster Stufe, sind sie etwas deutlicher zu hören, aber sobald ein Spiel läuft, gehen sie schon bei normaler Zimmerlautstärke komplett unter und sind nicht mehr zu hören. Aber da sie ja regelbar sind, kann man sie sich nach persönlicher Vorliebe einstellen. Durch die Gummifüße sind sie entkoppelt und es gibt keine nervige tieftonale Übertragung der Lüftervibrationen auf das Lowboard, was als zusätzliches Brummen zu hören wäre. Entkoppelt sind sie sowohl stehend als auch liegend, man hat also volle Flexibilität in der Aufstellung ohne einen negativen Einfluss auf die Geräuschentwicklung. Klare Kaufempfehlung, ich würde sie jederzeit wieder kaufen!
