AC Infinity AIRCOM S9, Quiet Cooling Fan System 17 Top-Exhaust for Receivers, Amps, DVR, AV Cabinet Components

The fan is very quiet and on Auto setting does exactly what it says…fan ramps up when the cabinet gets warmer, then slows down/shuts off when the cabinet is cool enough. We really have to try to hear it even when running on high - it’s remarkable quiet. Easy to forget it’s there/running. Definitely does the job.

I bought this for my Marantz SR7011 and I never thought about cooling my receiver. I have had an Integra for 10 years and never used any fans for cooling. I noticed my Marantz did get really warm and looked into getting a cooling system. Searched the forums and found AC infinity and this product and does what it says it will do. Fans are quiet and really keeps the receiver cool to the touch. The build quality is top notch and very sturdy. The packaging and presentation is all top quality stuff you would except from a product that charges three times the price. I wish I had got the model with digital display because the internal tempaeratures for this one is between 84-88 and sometimes I wish I could go a little bit cooler because even though it keeps its to 84 the internals are still warmer then the outside temperature of 84. Otherwise looks beautiful and fits perfect on my Marantz. Highly recommended.

My Denon receiver would randomly shutdown due to heat. After installing this unit, the shutdowns have stopped! The auto mode works very well. I little noisier that I would have hoped, but nothing distracting.

This thing rocks for receivers. Great purchase. Turns itself on and off and my receiver has not overheated since and i run it very loud. It can be noisy in a quiet environment but I have never heard it if literally anything else is making any kind of noise, for the most part its really quiet, except on its fastest setting, but you probably wont need that setting unless you are cooling off a large space.

Bought this to go on top of my brand new Denon AVR-X3700, because the top would get very warm, an the verge of what I would not be comfortable letting it run at. Denon says its fine, but I didnt feel comfortable leaving it like that in my AV closet. I just put this on top, and set it to smart mode, which was very easy using the included instructions, and not the AVR doesnt even get warm, plus the fan doesnt even go above 25% speed while driving all channels on music, so the noise is basically non-existent. I would absolutely buy another one if I needed one, and would highly recommend it for anyone needing extra cooling

Just awesome. Very thin profile, quiet and does a great job. Neither receiver or amp get warm now.

Nice air flow ..

I really like the design of the fan. Looks very good on top of the receiver. Draws the hot air from receiver underneath efficiently. It is only little louder than expected, but that is not a problem when playing music or else. Very Satisfied with purchase.

While the cooler does keep my receiver cool when the fan is on, the automatic feature does not work due to the location of the temperature sensor.

I havent had this very long but from what I can tell it works great seems to be built very well.
