Someone told me the computer fans are intermittent....made to run ever now and then, not full time...but they are cheap....how about an old refridge, they have a fan at the bottom....Grainger.....
good luck....I'm looking as well for a fan
Great work #14 post....I've thought of doing something similar, put with my own twist.....I found a small refrigerator with a window for the door. I would have enjoyed seeing the area where your fan and heat element are...."the behind the secret wall"
Have you thought on an automatic turner yet...
