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

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.

Basically, it is perfect. The power amp never becomes hot, you cannot hear anything when the fan is running, and the other components in the rack never become heated. My rack is enclosed on three sides, the back is totally open, but that still creates a potential problem with heat build up. The Infinity solves that problem. All of the amplifier heat goes out the back, and the rest of my components stay nice and cool. On top of that, I think that the price is pretty reasonable.

Its only been about a week, but so far it is working excellent. I put it on top of a Denon 6300h which was getting incredibly hot whether I played video games or blue rey movies or just listened to music. I went with auto setting and it comes on and off as needed. I felt the top of the denon avr and with out a doubt it is cooling it. So, without a doubt I recommend it. By the way it fits perfectly and looks great. You hardly know it is there. Very quiet and smooth.

i like using the item in smart mode and watching the indicators letting me know how it it working. the fan noise does not intrude into the sound system output at all.

It fits perfectly on top of my amplifier. The problem is, it did not dissipate the heat, just concentrated it on the top of the cabinet. I had to install an exhaust fan to take the excess heat out.

The features of this 3 x 120 mm. fan unit, programmable and thermostatic controls are very strong highly desirable selling points.

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.
