I just purchased a new designer home and I installed an attic fan with thermostate,I also installed a ceiling fan in the garage taken from one of the rooms inside. Then I installed a few grills or vents similar to that of the a/c inside on the ceiling one by the garage door and one near the fan .The attic is around 110.f the garage is 90.f The garage door is the biggest heat source and needs to be insulated.Thats next .If you insulate the ceiling I think it will trap the hot air in the garage.The key is air circulation from the garage into the attic,hot air rises.This was done with around 95-100 f temp.out.You can also install a solar attic fan over the garage and vent the ceiling with the hatch .
