room with air conditioning is one thing, and another thing without him,
and where the board is placed, in the casing or open, how the casing is vented.
from me will definitely be a response when I get board,
it will be in the metal casing with a pulling fan 80x80, a 30mm heatsink with fan 40x40.
and I am inclined to achieve a temperature below +50°C, up to the application of the Peltier element,
with the use of a the Peltier element less than +30°C, at maximum load MCU, here might need to use GPIO for DS18B20 and additional PWM.
I think it will be interesting for your projects
It could be a nice proposal indeed.
The problem of peltier devices, is that they are Current driven.
I was looking at some on the web, and there are some with less current consumption, like 800mw.
But needs to be done carefully, because of the current driven, but I think it could be feasible, for some 10C less.
