I bought two of the AC Infinity AIRPLATE S5, Quiet Cooling Fan System 8" with Speed Control, and the AC Infinity Controller 2, Fan Thermostat and Speed Controller after a friend bought a similar setup for his home. Years ago I had installed four computer case fans with an adjustable voltage DC transformer. I adjusted the voltage down until the noise was tolerable and functionally it did the job. The initial setup worked well because there was an AC outlet on the stereo receiver so I plugged in there and they came on automatically when the system was turned on. Two fans in the bottom of the cabinet blowing in and two fans at the top of the cabinet blowing out. After replacing the receiver the new one did not have AC out so I had to install a wall switch that required remembering to manually turn on when in use, and remembering to turn off when not. Not to mention realizing your equipment was cooking when you forgot to turn it on. That's all solved now.
The pictures are of the fans installed in the lower part of the cabinet. The top set look just like the unfiltered picture. When I removed my old fan setup there was a lot of lint build up over time so I cut a piece of nylon scrub pad to make a filter. As before, the bottom set blows in and the upper set blows out so I filtered the bottom set. Since the controller has two inputs you can actually set the bottom set just slightly higher than the top set as the filter may slightly slow the air flow. There is a slide switch fan speed control on the power cord for each set of fans and an electronic speed controller in the control box. Then I just set the controller to turn them on at 85 degrees and set the fan speeds at the slowest speed to cool the cabinet and it works beautifully and it is quieter than the make-shift setup I had before. If it needs a bit more air in the summer it's a snap to set one speed faster on the electronic controller. I did not install the controller in the cabinet as this was not necessary. It sets on the shelf with the receiver just inside the glass door at easy access height. Very pleased I found this product. It works great as a table piece in our home.
I have two of these installed. One for an Xbox in a cabinet and one for some fans on some Raspberry Pis. Easy to install and setup. Temp sensor seems accurate enough. Helpful when you have USB plugs that always have power. Helps to keep the fans from running 24/7 since they switch power to the fans based on temp. It works great as a table piece in our home.
