Perfect for heat buildup/AV unit
I buy a fair amount of pretty good products from Amazon and am generally too lazy to be enthusiastic enough to leave a review. This however, was worth doing one for. I fitted this to my wall built media cabinet, which has existing fans but was suffering heat buildup around the Devon AV unit. This has completely fixed the issue - the AV unit runs cold now, even turned the main cabinet fans down. Zero vibration or noise. Great, simple solution. Highly recommended (also can run in tandem with the other AC products I already use: controller/thermostat, case fans)

Great fans!
Used to help get rid of hot air from the PS5 and series x. Does its job. Mounted with about a 2 inch gap behind to help push the air out. Powered from a USB mains adapter so I could hide all the cabling behind my unit. The on/off switch is in the middle of both consoles for ease of access. Only visible in the picture because of camera flash, even tho their quite big their discrete and the noise is minimal. They are not silent, because the only thing you can hear when either console is on are these two running. Not noisy by any means but louder than the next gen.. Would recommend as they do their job 😊.

Quite and efferctive
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.

They're quiet but definitely audible even on the lowest setting.
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.

Keeps amp cool even on lowest setting
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.

Cooling Denon AVR
I have an aging Denon X4200 and it’s started to cut out after about 30 minutes. It’s always run hot but with the new fans even on low speed it runs very cool and no longer cuts out.

AC Infinity Fun
Acquistate assieme al suo controller per il raffreddamento di un sito amplificatore all'interno di un mobile. Davvero sorprendente la differenza di temperatura all'interno, si accendono automaticamente al raggiungimento di una determinata a temperatura. Consiglio assolutamente questo prodotto.

Does there purpose perfectly.
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.

Sessiz ve etkili
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.

Quiet and effective
Probably the most efficient USB fans out there. Good to cool AV or server racks that are not in their dedicated rooms (which is really what most people have to work with). There should be more AC Infinitys!
