I know many have setup custom cooling fans for providing adequate cooling and ventilation for home theatre equipment. My question is regarding control of those fans. I assume most are running AC fans as opposed to DC fans, but how are you turning them on and off.
I like the idea of having a thermostat kick them on and off, and while i have found quite of few around the $40 range, I was wondering if anyone has come accross something cheaper.
Or if an thermostat is even necessary, as opposed to simply leaving them on if equipment is on.
