Kegerator/Fermentation Chamber

Howdy guys

I'm new to the HomeBrewTalk. Longtime lurker first time poster. Anywho I wanted to share a kegerator/fermentation chamber I built from a side by side refrigerator. I used an InkBird controller on the freeze side to turn the compressor on and off and then have a controller on the refrigerator side that sends power to either a "hot" outlet or a "cold" outlet depending on the PV vs SP. The hot outlet I plan on plugging in a hot lamp to, but truthfully in Texas I haven't had much issue requiring heat. The cold side goes to a computer fan that in theory would pull air in from the freezer to the fridge side. Need more cold send more air. In practice this has not worked so well. I swapped out my slower fan for a high speed and it still doesn't seem to move enough air. Has anyone else built a system like this before, and if so, what sort of solutions did y'all come up with to move air more effectively?

Thanks for the help guys!

Nice set up, never seen that before

It works pretty good and for fermenting ales in my garage in Texas heat it holds 63 - 70 F pretty well. But I'd like to try my hand at lagering and can't move enough air to chill it down sufficiently.

I've got a similar setup I built about 2 years ago. I keep the freezer side at around 34F and the fridge side will get down to around 40F during the summer. One thing I noticed is even with my high powered fan, I ended up needing to open up the return holes to the freezer side. It would actually build up a decent amount of pressure on the fridge side. I bet you could also add a second fan on the bottom to blow air in reverse into the freezer side.
