Thanks for this great idea! I had all of these parts laying around. I took an old power supply that had a huge fan on it, reversed the fan, duct-taped the crap out of the box covering all of the holes. I then took a piece of beer hose, hot glued it to the box and ran it up the tower. I also had an old 12v 500ma PS laying around and used that to power it.
When running, the air only trickled out of the hose, but in 2 hours the tower was cold to the touch. My first beer that is usually more than half foam, was PERFECT! The damn thing really works! This is a Danby that I have also done the resistor mod to. It now is perfect. It seemed that for every beer I would drink, I would waste 1/4 to 1/2 in foam. I will post pics when I have time.
