I found a 2" computer fan, mounted it so it blows into the tower (screwed it into the top of the insode and left about 3/4 inch space above it..so it "hangs" on two screws). Works great and is enough to also circulate the air in my danby.
I may not be an expert, but I did stay at a Holiday Inn Express........ 6 months ago.
what is the point of cooling the tower? i keep my kegarotor in the garage where temps hit 100+ on a regular basis during the day and have yet to pour a hot beer because the tower is not cooled. i only drilled 1 1/8" holes for my lines so not alot of cold air gets up there. is this just a modification added for "coolness"(no pun lol) of your kegartor?
The issue is that the beer in the tower lines is warmer than the beer in the keg and CO2 will come out of solution more readily at warmer temps. Without tower cooling you're more prone to the first pour being foamier than subsequent pours.
Does it matter? Not necessarily. Is it cool to pimp the fridge? Most definitely
