Do you have one? I have a 6 pack of beer sitting on top of my kegs. My collar is about 7” tall. The kegs are cold, but the 6 packs are warm. I looked up a fan, and saw a question with an answer that made me think. The answer recommended not running any fan ever 24/7. Since I use a 2 stage temperature controller, I could plug the fan into the heat side of the controller. I think that would have the fan running at the wrong part of the cycle, though. I’d have to double up my plug to run it on the cold side. The freezer is plugged into that outlet. Or I could just run the fan all the time. What would you do?
