AC Infinity AIRCOM T8, Quiet Cooling Blower Fan System 17 Rear-Exhaust for Receivers, Amps, DVR, AV Cabinet Components

Excellent build quality and works extremely well. I own 4 units... 2 for my AV receivers and 1 for my ps4 pro and 1 for my Xbox One... this is definitely a great product with no issues. Buy it with confidence to keep your tech cool...

Pretty noisy in an open room. This should be in a closed cabinet at least 20 away. It has 80mm fans that look like they are in blowers which are loud anyway. Not a good design for quiet operation.

First off, any home audio enthusiast would dig this. Second, it works, period. Third, dust and other contaminants will have a harder time getting inside your receiver. Also, if you have cats who love to lay on warm things, this also works. As for noise level, yes if you have all of the fans going you will hear it. But with one or two fans going, which is plenty to keep it cool, you wont hear it. It has a smart feature that works based on a temperature you set that works approximately 10 degrees over. For example I set mine at 95 degrees and when the receiver hits 85 degrees a single fan comes on. It bounces back & forth for a while between a single fan to off. After a while, when your movie really gets cranking, it may bounce up to 86 to 87 degrees. The most it has taken to keep it cool after many hours it two fans, and unless youre on top of it listening you wont hear it, especially over any audio. I have a new high-end Denon receiver, and Denons are known for running hot, and if this keeps a Denon cool its a keeper. If youre considering this do yourself a favor and buy it already.

Good

Keeps my Denon X6500H much cooler, which will hopefully lead to longevity.

Using them in my home theater rack to keep my equipment cool, they Exhaust out the back.I like the features on these units automatic thermostat temperature readings they kick on when needed and you can Adjust the fans up-and-down when needed.

This unit is doing a fantastic job at keeping my Marantz cool during use. Well worth the cost

I own three of these: installation is simple and set-up is easy. But theres a problem with the power supply inlet. All three failed in less than six months after installation, even though the wall warts are still supplying juice. These units have never been moved or relocated; the fans remain in a constant position in my equipment stack and then they stop working without warning

Used the smart mode and I adjusted the fan speed to a lower setting because of the noise. However, the unit gets to its 4 degree spread between the probe temp and the set temp and CONTINUALLY cycles on and off when the receiver is in the standby mode. When the receiver is on and generating heat it seems better. Plan on going back to auto mode. Its a sleek design that fits nicely in my rack but its noisy at the highest fan speed. It would be better if this unit had a remote to turn it on and off with the rest of the equipment.

This seems to be a well thought out component cooler. There are several modes of operation and the cooler is very quiet. Its looks are as good as its function. So far I am very pleased with my purchase and I would not hesitate to recommend to others. If I ever need another one, It will be this
