AC InfinityAIRCOM S7, Quiet Cooling Fan System 12" Top-Exhaust for Receivers, Amps, DVR, AV Cabinet Components

Purchased a new receiver and noticed it was very warm even when on standby which got me searching for cooling equipment. Ordered the C7 even though the low price had me concerned and after running the receiver for an hour, it was cool to the touch. This model fits perfectly over the top vents on the case. Very simple to set up. Can't hear it running from across the room. Oh yeah, it was delivered the next day. Didn't see options for other colors, only black. Also a USB powered fan might be a good option since many of today's receivers have multiple ports.

Keeps my receiver cool

Excelente producto tal y como se describe y además se ve estéticamente fenomenal estoy encantado

Very quiet and can tell the airflow is working, my equipment is already several degrees cooler. Looks sleek.

My Stereo AMP was getting very hot in the cabinet other AV components are when pushing the AMP hard with volume (read rock concert loud). Got this dual fan for top venting on AMP and set it on Smart mode so it comes on automatically and adjusts fan speed every 2 degrees.You can't here fan with any level of volume you listen to, and it runs very quiet if you chose to just have it run all the time

I bought this for a receiver that runs a bit hot when pushed and it works very well at keeping the temps down.Noise is not really noticeable when amp and music is on. Build quality is good with multiple settings for fan speed and auto on/ off based on temps.The build quality is good and it’s a fairly thin unit that fits well in limited space.Great value for the price and I will be getting another for my other receivers throughout the house.

I needed something to cool off 3 power amps that I put in a cabinet. I noticed how hot the amps were getting and could smell the electronics heating up when I opened the cabinet door. Not good. I saw this fan on Amazon and it is exactly what I needed. I couldn't afford the larger T models but luckily AC Infinity makes the S7, very affordable and perfect for my needs. I placed the fan on top of the 3rd Amp in the cabinet and within a few minutes the heat had dissipated and the amps were cool as a cucumber. I set it to automatic and when the temp hits 88 degrees the fan kicks in and cools everything off. It is only an inch and a half tall and fits right on top on the 3rd Amp. It plugs into a normal wall outlet. Decent quality and I hope I get a few years out of it. It has 4 speeds, the 4th and highest speed is a little noisy so I set it to the 3rd speed which I cannot hear when watching TV. As the Amps cool off this fan will drop to the lower speeds as the temperature lowers in increments of 2 degrees. The 1st and 2nd speeds are silent. If your electronics are heating up you should definitely consider getting an S7.

I noticed that when I listen to my sound system at higher levels for extended periods of time, the heat sinks are very warm ... actually too warm to hold my hand against them for very long at all. I have a very expensive McIntosh MA252 audio amplifier; it sounds great (I've had McIntosh equipment since around 1973, and it holds up very well). This MA252 is a newer integrated amplifier and I plan to use it for a long time, and most likely at higher sound levels, thus generating lots of heat. Being an electrician by trade, I fully realize that heat can be one of the most detrimental things to the longevity of electronic equipment.This neat little fan is built nicely and seems quite sturdy. It has some different modes of operation. I use it in the mode, where it only turns on when the temperature gets above a certain level and then runs faster or slower, depending on how warm the amplifier gets; that way, it isn't making noise that is louder than the program material coming out of the amplifier is. And, of course, if the amp is giving off less heat, the fan slows down. I am very happy with it; it also is very unobtrusive, so. it is not any kind of obnoxious accessory that sticks out like a sore thumb, its black finish matches quite nicely with the black finish of my heat sinks and most of the amplifier. I have had it for about 8 months at this point, and I am quite happy with it.
