Any help is appreciated thank you!
Hey I've built one of these puppies... are you referring to the one that has the upper level for 2 carboys, and under neath are 3 compartments for ice blocks??? If so, you put like a "false back" on one of the end compartments, and cut a hole in that and seal your fan in there, so that behind the fan, there is like 5 or 6 inches before you hit the back of the actual fermentation box. Then put a big hole in the "floor" of your ferm side, so the fan will blow air up into the fermentation portion of the box. I cut some thin plywood and ran it up to the top of the box, making an air duct so that the cold air would be forced all the way up and then fall (warm air rises to the top) so that way you are pushing the warm air to go through the ice block compartments as opposed to cooling already cool air.
Clear as mud, but hopefully I helped. I'll be firing mine up today!!!
