Percolation? Heat soak? Don't drive during summer??

For argument's sake what if it isn't cool air outside and it's one of those 117 degree Arizona days and it's 117 degree being sucked in to the radiator with the fan and the inside of the garage is actually 75° from the air conditioner in the house?....

Also, the garage might start at 75, but once that door opens it quickly reaches outside temps... Heck, my garage typically didn't even reach the house temp. On a 110-115 degree day (was 118F the day I left the city) my garage was typically 90-95.
