Meraviglia Upholstered Sofa Bed

This is a really 'cool cabinet fan system. We have a custom built-in entertainment cabinet in our family room. The top section has the flat screen LCD TV with the Wii equipment and the middle section has an audio system, TiVo, CD player and a VCR, (I know why a VCR). The new TiVo and the 25-year old audio system generate a fair amount of combined heat that I wanted to remove. I did a search on Amazon for cooling fans and looked at several options. Having a system that was temperature controlled and could adjust the speed of the fans was very attractive so I decided to focus on that solution and was very impressed with the features of the AC Infinity products. I ordered the AC Infinity AI-ATC, Fan Thermostat and Speed Controller, MULTIFAN S7, Quiet Dual 120mm USB Fan, and MULTIFAN S5, Quiet Dual 80mm USB Fan. Everything arrived in two days; the three items were well packed and arrived safely.

Now I could actually see and test what I got and found they were even better than I had expected. The controller is a perfect size and flush mounts in my equipment cabinet. The temperature probe has a long enough wire to run it down and over to place on the audio amp and under the TiVo where the maximum heat is generated. The fans have large rubber grommets on each corner to stand on or mount with and no vibration is transmitted through. One set of fans are in the equipment section behind the equipment blowing air out through the equipment towards the open room. The second set is located in the TV section also blowing from inside through the TV towards the room. Running at full speed in a quiet room you can of course hear the mechanical fan and wind noise. However, when the audio is on, even at a comfortably low, watch the news level, the fan sound level drops below the audio program level and is no longer discernable. With the controller running in the 'smart mode the fan speed is reduced when the equipment temperature is within two-degrees (or four) of the desired set temperature. As they say on TV 'Just set it and forget it, the controller keeps the fans running as long as the equipment is generating heat above the set point. When the audio amp is turned off and the TiVo goes into stand-by the fans cool them down and then shut off. When I am able to locate my hole cutting drill I will add some ventilating holes in the top of the cabinet and between the sections in order to improve the circulation of fresh cooler air into the cabinet to improve the efficiency.

I am so pleased with this cooling solution that I am ordering another setup for our weekend summer cottage up north at the lake. Again, there is an audio system but in addition there is a Magic Jack phone module and the cable modem / WiFi router generating heat. They are in a confined space that gets hot so I had placed a small fan in there to circulate the air. When we are there, I plug in the Magic Jack and turn on the fan. Now I will be able to automate the cooling.

If you are looking for a great way to cool down your expensive equipment this is an inexpensive solution that I highly recommend. The comfort level exceeded expectations. Assembly was straightforward.
