I actually bought 2 of these -- an S7 to cool a DirecTV DVR, Roku (those suckers get hot!), and ethernet switch, and then an S9 to cool a Denon AVRX4200w receiver

Keeps our receiver nice and cool.

so I feel the the receiver is staying cooler now with the air moving.

Garage gets very hot during the summer this keeps my receiver from overheating very well allows you to crank up the volume

Hi everyoneThe aircom S7 is a great product I recommend this compact receiver cooler to all , I have a pioneer elite sc-91 & it keeps it cool under 85 degrees it has a couple of settings I prefer the auto mode where it kicks in when it senses it's warming up on the

This two fan S7 12" long model performs the job perfectly though - kicks on and off automatically, sets the fan speed appropriately, keeps the receiver lovely and cool and exhausts the hot air upwards.

Bought it for our semi expensive receiver, which operates everything electronic that we use for entertainment

Used this to cool a Denon AV receiver, THIS IS CRUCIAL FOR ANY ENCLOSED RECEIVER

Working great, keeping the receiver cool.

I was originally looking at their S8 model (which is 17" long - the same as my receiver) which has 3 cooling fans....but that model exhausts the hot air to the rear of the unit, which isn't much help in my setup.

Works a advertised, my receiver never gets hot or overheats anymore.

Keeps my audio receiver cool

Easy set up, easy running, and I now have a cool receiver
