Yes, you can see it hanging behind the back row of kegs in the second picture. It looks like this up close:
40mm 12V DC heat sink fan mounted in a plastic case, a shop vac transition piece (I think it's for 1.25" to 2" hoses) I picked up at Lowes stuck through a hole cut in the case half, then I heated up the end of a four foot piece of 1" ID vinyl hose and pushed it over the transition piece.
I stuffed the tube up into the tower column about half way and ran the beer lines around it. The column is insulated with neoprene and the faucet box is insulated with an inch and a half of foam. The whole thing works well enough to get the faucets to sweat during humid weather...
