I worked at this problem and found what seems to be a decent solution. Although the best solution would be a mini-split. I recorded my garage temp over a 2 week time period. I insulated the doors, North facing, insulated the ceiling, and installed two regular ceiling fans. In the early AM I open the doors and turn on the two ceiling fans for about 20 minutes. Trying to move hot air out and cooler morning air in. I then close them and turn off the fans.

I consistently maintain about 10 degrees cooler in the garage then before doing any of these add on's. I have a large 3 car garage that is over 1000 square feet. My total cost to do these changes was under $800. Fans were used so mostly for the insulation. But it has helped considerably to maintain a lower inside temperature.
