I got my blower fan connected to continuous power, thanks to a little help from Psychodad. My board is located in the back, not on the top, like some of the older models. It was a simple task of taking the tower and the top off, drilling a hole through the plastic tube, running the wires through the hole and down the back of fridge. I didn't have to drill any holes through the fridge itself, great!
My blower didn't come with a bracket like the others I've seen in the pics. So mine is just sitting in the corner. I'm getting a little vibration noise outside the fridge, but nothing major. Right now I'm just using 1" plastic tubing up to the tower hole, attached via duct tape
. I'll get more elaborate and permanent once I find the right pieces I need to drill a 3" hole.
For now though, my Danby is running at 30 - 34 degrees measured from the top of the keg by an indoor/outdoor digital thermometer from the home store. No more foamies... except for a tiny bit at my first pour. I'm very happy.
Thanks everyone for the help.
