Very simple and it works great. It just pumps cold air up to the top of the tower!!
That's a great idea! I have a pass through tower that needs cooling. I currently have a little muffin fan that pushes air through it, but it works better for the faucets on the side the fan's mounted to. My clearances are also so tight that the fan makes it hard situate things so that the lid closes properly after changing kegs. I think I might give this a try, since the cooling would be more even, and I could mount it out of the way.
