Temp Controller Overview

[David Kennedy]

I had a very simple way I was thinking to make a fermentation chamber, I have a 7 cu ft freezer I store my kegged beer in at 34 F, I was going to get a non working 7 cu ft freezer and sit it next to my working one. Here is where it gets cool, was going to connect the 2 freezers with a insulated duct pipe with a fan hooked up to a cheap controller, when the fermentation chamber needs cooling it will just turn on the fan and blow a little cool air until my set point is achieved. Does this sound like it would work?
