In a certain way I agree that your install needs more cooling than the usual ones because you live in a terribly hot city. That's the point here, I think. Most Empegs get sold in Europe, where such temperatures are not that usual. So, most Empegs will never go through such extreme conditions. But in Miami, or any other place where heat is sometimes overwhelming (I really don't like heat. I lived in Brasil for two years and had enough) some additional cooling may be mandatory.
