AC Infinity AIRCOM S6, Quiet Cooling Blower Fan System 12 Rear-Exhaust for Receivers, Amps, DVR, AV Cabinet Components

This unit really does the job...automatic mode works as advertised.

I purchased the Aircom S6 to cool my new Marantz SR6012 AVR which is known to run very warm. I prefer to keep my electronics cool. This unit works great. Nicely built, quiet as can be. Highly recommended. I sure all of their units would be great based on seeing and using the S6. I went with the smaller unit as my cabinet also has some cooling as does my 5 channel power amp.

The unit does in fact cool the receiver, however even in Auto Mode, the fan runs constantly which I did not expect (even when we the radio is off). That Is a problem for my setup and use. Is there a solution for this?

Great product cooks my receiver great and very quiet

This works exactly as advertised. It keeps myvideo amp cool. Like the auto temp setting and it does it job without any attention on my part. Sound level is quiet enough that I cannot hear it even at low volume settings.

Works very well. Very quiet and has different settings that are easy to use. This is my second cooling fan from AC Infinity. I use one for my PreAmp and this one is for my Amp. Low profile. Great buy.

Works fantastic for cooling down av receiver in an enclosed cabinet.

The Aircom S6 works great for keeping my A/V receiver cool. My last three surround receivers have been Denons and none of them have failed. And thats partly because I either always made sure they were well ventilated or had a muffin fan (thin, DC powered fan, like you find in desktop computers) sitting on top of them. I would run the fan at a lower voltage, so it would spin more slowly and thus was effectively silent at 6 feet away. My 4k capable Denon receiver has fans in it, but they never heard them run under everyday usage and the unit gets hot (when I tried it with my fan shut off for a day). This is because the cabinet I have had to switch to has less clearance above than is ideal. I was on my third muffin fan, because they typically last about 5 years. And I was literally about to pull the trigger on a fourth fan, because number three was starting to show its age with being noisier. Thats when a friend turned me onto the Aircom series of coolers (was surprised I wasnt familiar, since Im keep up on A/V gear!). He had just bought one himself and for his hot amplifier and is very happy with it. And then I come to find out that another friend also recently bought one for his new 4k Marantz receiver. Both of them were very happy with them. (One has the S6, the other one of the higher models with LCD). Both of them said they wished the unit was slightly quieter on the lowest setting, but they can live with it. When selecting the right model for me, I decided I didnt need fancy, just basic cooling. Thus my choice of the S6. As you may already know the S6 is one of the Aircom coolers that sucks in air from the bottom and blows it out the rear. This is what you want if either you have limited clearance above the receiver, or you have a more closed off cabinet (because having a model that blows upward will not push the hot air out of the cabinet, just circulate it). I suspect for most people the rear-blowing models are the best choice. I keep my S6 on the auto/smart mode and the lowest speed setting, and it keeps my receiver just slightly warm to the touch, just like I want. I would never use the higher speeds, as they are way too loud (definitely for an equipment room/closet situation only). I agree with my friends that the S6 could be quieter on the lowest setting. It is unfortunately slightly audible during the quietest passages. But this has only been noticeable on maybe two occasions so far. But this audibility is one of the reasons that I give the Aircom S6 four stars, instead of five. If it was effectively silent at a distance of 6 feet, I would gladly award it the full five stars. I hope that this product has a long lifespan. I expect it to last at least 5 years without getting any noisier. If it doesnt, I will go back to a muffin fan (that is a fraction of the price). The other reason I cannot give the Aircom product five stars is that the power connector on the rear is easily disconnected when you are working with other cables in A/V system (or have an animal that is adventurous and refuses to stay out of your cables). There needs to be some kind of way to secure the connector, or at a minimum, a cord clip that holds the cord firm when it gets tugged. I ended up zip-tie-ing the cord to one of the slats on the back of the unit. AC Infinity should make a Gen. 2 of their product range that is even quieter and has a means to secure the power cord or connector. Then they would have a 5 Star product.

Perfect size, thin, fit on top of Yamaha receiver with no issue. Put it in automatic mode turns on at 88 degrees, fan speeds up only as high as needed to keep temperature down. Cannot hear it even after watching movies all day. Easy to setup, great product

Quiet and efficient.
