is the temp inside, where you want to place the wineador in the 100's?
I would look for a cool, dark place (inside a closet? or a basement? etc..)..
Otherwise, I am not sure a thermoelectic wineador could keep up...
It would certainly reduce the temp... but I dont know that even if it was running 24 hours a day that you could actually get the internal temperature down to 65 if your external temp is in excess of 100..
