as long as you keep the lines flowing regularly bacteria/spoilage
shouldn't be an issue. (Don't go more than a couple days without a beer!)

The easiest method of cooling the draft tower is get a cheap computer
fan and blow air up into the tower.

your only issue is how to power it, you should be able to get an old
power adapter (I believe its 5VDC, but you can check on the fan, it
doesnt matter if you over-volt a little, (6-7VDC should be fine) as long
as you add a variable resistor, and dont make the fan spin too fast.
i.e. volume control type knob).

I imagine it would cost about $20 to make one.

Mine has a duct that comes off the evaporator fan, but then I have a
very fancy kegerator:

(I have an older version of this one
