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

This is a nice quiet fan protecting a $1000 Denon Audio Receiver. It installs easily and seems to be eliminating the hot air.

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

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.

Hello,

So far so good. Using for surround receiver that was overheating when I listened to music. I have it set to turn on based on its temp sensor. Working great. Quiet. It says it should go on top, so that’s how I am using it, but would rather it on bottom. May try that later.

Website description: Programming features two thermal trigger modes and four speed control options.

AS advertised

Works as described. The smart mode is nice. So far so good.

AC AIRCOM S9 is, very easy to set up and operate. I believe, it is worth your money.

Perfect size...works great
