AC Infinity, MULTIFAN S7 Quiet USB Cooling Fan

These fans were brilliant. Using them freestanding to cool a cabinet shelf with a PS5 and there was a massive drop in the temperature. Quiet and solidly built.

Very good product. Lasting well. Used for a good while now. Used to keep plants happy 😊 very quiet too, you can keep them running night and day and you dont hear them... well , just a whisper.. literally.

Great fans, great price and quiet! I only need the lowest setting and it`s nice and cool in my arcade cabinet

The fans work fine although you can definitely hear them.I had to remove one side of the grills on both as they were resonating with the fans and causing a sine wave sound which was annoying until I figured it out.They move a good amount of air and are keeping my AVR cool which is all I wanted them for.

I bought this to cool my switch rack, fits perfectly and is configurable fan speeds and temperature control is great, the display is clear and easy to use, great bit of kit

This is a day 5 review so keep that in mind. Should anything go wrong I will try and update.I bought these fans to try and cool the inside of my PC, Specifically my 2 fan MSI armour gtx 1080. Playing Assassin's Creed Odyssey on ultra was running the temperature up to an average of 79 peaking at 82 degrees. Still within acceptable limits but high for my liking. Fans arrived and where unboxed, attached and running within 5 minutes of arrival. Running straight from PC USB port. One at front for air in one at rear for exhaust. Set speed to Medium. Game now runs at an average of 74/5 peaks at 78 degrees so greatly improved airflow. Even on high the fans are Super quiet. With one fan at the rear and one at the fron I still had a good amount of cable for further separation should it be needed.Makers state the fans should last up to 67,000 hours and have a two year warranty so more than enough life in them for the money. I would advise buying 120 mm Dust covers should you wish to use these for air intake.I was so impressed I bought another two within days.

Excellent build quality and plenty of cable to hide the PSU well away from the fans and the AVR it is cooling.They are, however, not really silent "out of the box" even at the "Low" setting. It is not that they are noisy but they do make a very low but annoying sound of turbulence created between the fan blades, the protective grille and the surface of the AVR. Luckily it can easily be silenced by creating a bit more distance. I have solved it by placing the original rubber feet on four thin pieces of Poron.Though the cabinet allows a decent passive air flow my fanless 9 x 200 W AVR runs dangerously hot but for normal use even the lowest fan speed keeps it surprisingly cool. When watching a loud movie I will probably use the medium setting. BTW I turn the fans on/off with a Philips Hue a smartplug.Highly recommended!

These fans are fantastic. Without them my rotel amp runs pretty hot, 10 mins with the vol at 9 o'clock and it is warm to the touch. An hour at 10 o'clock and the case is very hot. If I push it much more the amp shuts off. With two of these sat on the top of the case, I can go as loud as I want for hours, and even with the fans on their lowest setting the case of the amp is cold. Clearly this will make the amp last much longer. On the minimum setting, they are pretty quiet. You can just hear them from a few feet away in a quiet room.

Ho acquistato queste ventole doppie da 120 mm per raffreddare i dispositivi all'interno di un mobile e sono rimasto davvero sorpreso dall'incredibile silenziosità e dall'ottimo flusso d'aria. La possibilità di regolare la velocità è utilissima. Costruzione solida e componenti di altissima qualità. Consigliatissime!

I’m using this to cool my PS5 inside a closed off IKEA cabinet.It works surprisingly well (pulling cool air in, pushing hot air out). The fans of my PS5 have never switched into jet engine mode since installing these. They’re powered with the default USB output and switch on when the PS5 switches on.

Degelijk en stil. Zoals je van een AV koeling specialist mag verwachten. Voldoende flow voor efficiente koeling. Koppelbaar tot 4 fans op 1 USB voeding.

I don't always right a review but was so impress by these fans that I to write a few words.I use these on top a Denon X3400H receiver that only has about 2.5" of space left above the AVR well in the TV unit, so not much airflow even though theirs plenty of space for air flow on the sides of the AVR like most receivers these days theirs no internal fans, so the hot air just dissipates out the top of the AVR naturally and if your units in a TV unit odds are its gonna run quite warm to the touch.These fans work amazing! simply place them on top your AVR (infinity logos facing up) to pull the hot air out of your unit and it will stay nice and cool to the touch. The fans rubber isolation feet are a nice feature, as well as the built in metal fan grills/dust shields (little touches like that along with its ease of use and fair price was the reason I want with this infinity fan set over making a DIY setup using spare PC fans) and the ease of use/versatility is a big plus, being that these are USB fans you can plug them either directly into your AVRs USB port (so they power on with the unit) or into a USB power block plugged into a wall/power-strip and you can simply use the controller to turn them off when not in use or just run them switched on all the time... personally I never use my AVRs USB port so I just plug the fans directly into it and being that I only have a front USB port on my AVR, to keep things as clean as possible I choose to run the cord under the AVR tucked behind one of the AVR feet and out the side of the unit, twist tying the excess wire which leaves the controller nice and handy beside my AVR.I was worried that with the fans on top of my AVR that there wouldn't be enough space left to actually allow the fans to circulate the air out side of my TV unit... there's likely only about 1/2" of space left above the fans but to my surprise even on the low setting they keep my AVR vary nice and cool for hours... vary silent fans and vary efficient I haven't really had the need to even go above the lowest setting to keep my AVR cool, 90% of the time its low and odd times i'll set it to med or high to really exhaust any stagnant hot air that might be inside.Overall I highly recommend these for the price they're a must to keep any of your expensive electronics that run hot nice and cool... its a small investment to prolong the life of your much more expensive gear.

Ürünü ses sistemime ilave soğutma sağlaması için aldım ve gerçekten etkisini hemen gösterdi. Çift fanlı versiyonu en hızlı kademede bile rahatsız etmiyor ve üfleme hızları da gayet tatmin edici. Mataryel tasarımları kalitesini belli ediyor.
