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

Works great and quiet

Purchase this to keep my Marantz receiver cool as they run hot.I set it to smart and it automatically adjusts fan speed to keep it running cool. I see the fans speed meter fluctuating during action movies when my receiver is working harder -) glad I bought it,I believe it will extend the life of my receiver.

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

I bought 2 of these, one for my Marantz sr7011 and my Monolith Multi-Channel Power Amplifier With 7x200 Watt and they work great, they turn on at 89 degrees and turn off at 84 degrees . perfect thank you

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

Well built, slim, quiet. The cooling is effective.

This is truly the simplest and most cost effective solution to cooling components, especially on the shelf or in a cabinet. The auto mode saves electricity. The width dimension was an exact match to my Yamaha RXA2070 receiver. The superior slim design is appealing and most of all; the variable fan system is very quite.

I have a Denon AVR-X6400H receiver. This thing has no problem powering my 9-channel ATMOS setup. It does, however, put out a lot of heat. I decided to avoid a receiver meltdown and augment cooling duty with the AIRCOM S9. At 17 wide it is the same width as the Denon. The finish of the S9 is also similar. I think it looks great sitting atop my AVR. Two buttons on the faceplate provide all the adjustability I need. One caveat - the S9 is quiet, not silent. This is not a criticism as sound should be expected from a unit that can move as much air as the S9. Just keep it in mind. My AVR stand is about 8 feet behind my listening position. I will place a couple of foam acoustic panels on the side of the stand facing the listening position and I am confident that will do the trick. So, it works great, looks great and I would recommend it.

Great product and seller! Love it!

Worked great since October 2016 until today (5/5/2017). It quit working, no funny noises or puff of smoke. Bad timing, its over 100F here in AZ.
