I don't care what you believe.
My north facing 3 car garage gets over 110 alot in the summer. It's 92 degrees in there now and it's only 79 outside.
The couple I was referring to have the thermostat in their attic set at 110 degrees on and off @ 90 degrees. Temps up there soar to over 125 degrees all summer long.
30+ degrees is easily accessible in the attic which is what I was referencing. I bet I could get 25 or 30 in my garage in the summer.
