I am going to install a couple of cooling fans inside on of my hotter running 1 gauge locs. Especially with running it outdoors here in AZ, the added air circulation will help keep the circuitry from frying. So here is my question. I can get very good quality, and inexpensive fans from the local computer store (your basic 12v DC fans) or I can by a much more expensive AC fan. The loc uses AC power from the tracks, and for the one fan I want to run at all times, I need to tap off the AC power. The question is, what happens if I use a DC fan with AC power? I did an experiment and touched the wires to the track directly and the fan seems to have worked normally (although with a bit of a hum, very quiet however). Will it eventually burn out? or is it just going to make this hum and that's all? Short version.. can I use a DC fan on an AC power source?
