home -made incubators

Okay briefly hijacking the thread to ask a question: I have a mini coke fridge I'm going to convert, and it's a bit shorter than @PitOnTheProwl's cooler. About how tall would it need to be before you start considering adding a fan element?

Pic of the same model fridge I have that someone else also converted into a 'bator (which makes me giggle).

All you can do is run it and see what your temperatures are in different locations and go from there.

This ^^^ 100% and I would add that you need to run it in a "real world" configuration, everything in place except the eggs, for at least 12 hrs to determine if the temps are uniform and stable. I actually had fans ready to go in for my current design but realized in my dry runs that I didn't need them. A good thing to know also in this process is how long it takes to get it up and stable from room temp.
