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

Best product out there in this regard. 5 stars

Works well for my Marantz 5006 that is on all the time. The receiver runs quire warm at idle, and has had issues with going into temp protection in heavy use, and I was worried about longevity. My enclosure doesnt give nearly the amount of air space the manual requires. The profile of this cooler fits perfectly with the curved edges of the receiver, and at 1.5 tall it just fits in the tight space in the cabinet. It even matches the depth of my receiver perfectly. I leave it in smart mode at 1/4 power, and its basically inaudible and provides probably more airflow than the amp would get in free air. I havent put it to a heavy test yet with extended loud music listening, but in a light test it didnt kick up over a quarter power. At full tilt I would think it would provide some serious cooling. It gets somewhat loud at full tilt. I wish the light on the front wasnt so bright. Overall it seems like a good deal. Much better integrated than any fan setup I would have ghetto rigged up.

My Tivo runs very hot and this fan has worked wonderfully keeping thr cabinet cool. Highly recommend.

It works as advertised.

Well made like a industrial computer or HiFi gear. Looks like it belongs with the rest of the system. Cools well and quietly. I only use the lowest 2 speed settings because thats all thats needed for my amplifier. The top two speeds would be too noticeable for me. The rear exhaust works well for my setup. I have been using homegrown improvised cooling until now, this is much better.

Just as described

I have an enclosed cabinet for my a/v receiver. When the cabinet was closed my receiver would overheat, had to keep cabinet open, not good with my grandchildren running around. With is unit I can keep cabinet closed and it very efficiently keeps receiver cool. Love the automatic function where it adjusts fan speed when needed. On low speeds very quiet, of course when at it highest speed you can hear it but not enough to distract from listening experience. Very well made. Wish I had purchased this sooner because my older receiver overheated and had to replace it. This keeps my newer cool.

Works as advertised

works well and quiet. got it set to auto, and works great.

Bought this for my Onkyo reciever after noticing it getting very hot. I had read the reviews about noise level being excessive, on high that is true. I run it in auti and using my reciever for 7.1 surround at a comfortable volume level the fans have only run at low speeds and there is no noticeable sound coming from the unit. Very happy with coming effectiveness and price of this unit.
