I love it! What can you say, it does its job quietly !!!!

I didn't realize when I moved from an Onkyo to Denon A/V receiver that the Denon would run so much hotter. In my entertainment center, the temps got way too high for comfort (and the likely life expectancy of my expensive receiver). This thing really works well. I set it to 'smart mode' via the easy instructions, and it does what it needs to; turns on when needed, and adjusts the fan appropriately. In my situation, the fan goes to 1/2 speed to keep the receiver nice and cool when playing 9.2.2 Dolby Atmos encoded movies. The cabinet stays at room temperature. If you manually set the fan to high speed, it is quite loud for this type of device, but I have not had it go above 1/2 speed in smart mode where it is barely noticeable. I also have some Crown amps going for the subs which have also fans, and they are likely contributing to the very low fan noise (which disappears with any type of speaker output). I can't hear them unless I put my ear close to the entertainment center, but my wife can at completely silent points in movies. You do need an open back for this particular unit to vent out of, and some way to get air from the bottom of your receiver. I cut some holes in my receiver's shelf to improve the air flow.

Purchased direct from AC Infinity 1 month ago. I learned that setting up with fans limited to 1/2 speed does the cooling job on my Denon 4520 in a console. Flexible set-up allows me to run cooling below an audible threshold with a little set-up experimentation. Good product. Case build reminds me of the OPPO players from 15yrs-ago, nice feel to it.

This unit was the answer to my problem. My new Denon home theater system was creating an alarming amount of heat inside the cabinet that I keep my electronics in. Trouble free and automatic. It keeps things cool. I definitely recommend this fan unit!

Blends in well visually with recent Marantz gear- looks like an extension of the equipment.Good value.

Keeps my Denon AVR receiver from overheating

I liked everything it does

I was impressed with how the unit was packaged. The unit is well built with a solid feel. It was easy to set up. Fans are quiet but adequately move enough air.

I own 2 of these, they work great, keeps my receiver and amps cool during several hours of watching movies.

Great units. Have a 12 and 17 inch units. Perfect quality and capability.

quiet and keeps receiv cool. love it. auto setting works as it should

Where has this product been all my life?!! It completely tames the heat buildup in my A/V equipment cabinet. I used to leave the door ajar to prevent the 5-channel amp from over-heating and that allowed dust to eventually build up inside the cabinet. Now I can leave the door closed while the built-in ventilation system in combination with this product keeps everything cool and clean!AC Infinity needs to market their products through major electronics stores like Crutchfield and Music Direct so people can learn about them!I'm updating this review to further praise this product. The manufacturer forgot to say that this product will resume its last program if power is disconnected and later reconnected! A very useful feature.

I habitually swap/change/switch stereo components, and as you know, covering up the top vents on any piece of equipment is never a good idea. The Aircom S8 fits my setup perfectly. I have it set to auto, which only runs the fan when needed and the fan can only be heard (faintly) after I shut everything down for the night. Keeps my Denon receiver nice and cool and acts as another shelf that I can put components on. Build quality is excellent and with all the component swapping, I have yet to scratch the top. Heat is the killer of electronics. This will help prolong the life of your devices.

Pleased with how quiet it is. In auto mode it comes on at 1\4 speed and ramps up to 1/2 speed and shuts off automatically when amp is turned off after it cools down. On full speed it is loud, and volume would need to be turned way up. This replaced a cabinet that had 4 120mm computer fans that I could always hear running.

This level of cooling should be built into amplifiers - but only hi-end gear get that.So fits perfectly over my Onkyo A/V Receiver- and I'm hoping it'll extend the life of my electronics.

MET MY EXPECTATIONS!

Works as designed. I'm utilizing the automatic mode.
