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

Instant solution! My picture and sound cut off after extended use. I changed the HDMI cables thinking they were the problem, which they werent. I found out my Denon receiver was running very hot after extended use. Since the receiver is the heart of my system I felt running it cooler would take care of my problem. I ordered AIRCOM S9, plugged it in, used the default setup, placed it over my receiver and let it do its thing. The AIRCOM S9 did its thing automatically! It kept my Denon so much cooler and the problem is now gone. The fans are so quiet. I will eventually replace my receiver but for sure I will have the AIRCOM S9 an integral part of my entertainment system. Just buy it. It will extend the life of your electronic components and ensure their reliability for years to come.

Works great.

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

This unit pretty much fits perfectly over my Denon AVR.

Bought a stereo receiver that I knew would run hot so got this to help keep it cool. This thing works exactly as its supposed to. Place it on top of your receiver, plug it in and set the maximum speed of the fan. Is senses the temperature of the air from the receiver and automatically adjusts the fan speed accordingly. Nice and quiet, unless its on the highest fan setting, but you would only hear it slightly if the room was quiet. Just love when something actually works well without having to put in more effort. I also dont feel I need the more expensive version. This does exactly what I need.

I have a new system which heats up much more than my previous one did. This keeps it much cooler. I leave it on auto and it turns on and off when it gets a certain temperature. I was apprehensive when I bought it. Since then, Im sold on it. Excellent unit and very quiet.

fantastic product. have it sitting on top of my receiver/amp in a cabinet - very quiet and effective

Keeps my Anthem 720 nice and cooooool. Never goes above half speed very quiet quality build. I am very happy with purchase and performance.

I have been using this for several months now and I can keep my cabinet closed. It keeps my Denon 4300 cool (and the rest of the gear tivo, appletv, amazon tv, bluray)

This product works exactly as advertised and could not be easier to set up. Would purchase again in a heartbeat. It may be expensive relative to other fan systems, but once you account for its computer thermostat controls, and how quiet the fans themselves are, it is worth the price.
