> and rely just on convection to pull away the heat Interesting, I've definitely seen a normal sized house fridge with a fan on the hot side, but I don't know what is typical. > I think you'll find fridge fans not as generic nor replacements as easy to find as you might hope. Current generation probably not, but there's no reason these can't be your typical $20 computer case fan, especially on the hot side where there's no worries about condensation... for peltier elements you could even stick a off the shelf CPU heat sink on top (though presumably at scale you would build the heat sink custom).
