AC Infinity AIRCOM S8, Quiet Cooling Blower Fan System 17 Rear-Exhaust for Receivers, Amps, DVR, AV Cabinet Components

This is a must for those with good audio equipment. This fan will keep your system cool from ever overheating and wearing out parts of your machine circuitry. This small investment will save you lots of cash in the long term. Wish I had bought one long time ago!

I’ve had the unit for a few weeks. Watched two Netflix streaming movies and one Blu-ray disc at a volume of about -16 dB. At that volume the movies are rockin pretty hard. Unit is set on auto with a fan speed of 2 and sits on top of a Yamaha RXV685 in a 5.1.2 setup. After about 20 minutes the unit turns on and stays on throughout the movies. It is non-audible when running, exhausting out back. After movie end, about 2 hours, the heat of the receiver is barely noticeable and the S8 tuns off in about 10 minutes after turning off the receiver. Previous to the ARCOM S8, the receiver pumped out pretty noticeable heat while playing a blue ray disc. Got to say, I think the unit does its job. And I’m happy with the purchase.

I just purchased the Denon AVRX4700H and am using it in a 5.4.2 configuration. I have it sitting in an enclosed cabinet. I even installed fans on the back panel of the cabinet to help circulation of air. Even with this, the Denon runs alarmingly hot. With modern day AVRs, the manufacturers are no longer installing switched a/c outlets on the back to alow for fans or other peripherals to turn on when you power up your system. I purchased the S8 which has a thermal switch that engages the fans. This psrticular model exhausts the air to the back of cabinet. I set it in auto and selected the middle fan speed. 5 minutes into Mulan, the unit kicked on and was dead silent with cabinet doors shut. Its amazing how cool this kept the Denon playing at near reference level. With the doors open, I could not hear the fans running from 11 feet with the middle speed selected. With doors closed, the high setting was still very hard to hear. A cool feature is the smart mode which turns fans on when heat is sensed and varies fan speed depending on temperature variations. The build quality is fantastic, and the larger, 3 fan version fits the standard size AVR perfectly. Other reviewers took the feet off and installed rubber weather stripping along base to increase efficiency....I dont think this is required and can potentially damage temp sensor. Exceeded all expectations! Highly recommended!

Does what its designed to do and does it well.

This level of cooling should be built into amplifiers - but only hi-end gear get that.

AV receivers primarily fail because heat issues. So I bought this one. If you have an expensive receiver, this is a worthy investment. I have Marantz 6015 AV receiver for which I paid $2200 with tax. It sits well on top of it. Looks as if made for it. Auto cooling keeps the receiver cool all the time and increases air flow.

If the fan is on high it is too loud ,but if it is on low you can’t hear it and it works well.

Works great.

Function as described. Very satisfied.

Very satisfied with my purchase.
