Ideally your attic space will stay in the same temperature range 105 115 degrees and the only true way to tell is to stick a thermometer into your attic overnight and check the reading every couple hours.

Ideal attic temperatures shouldn t be more than 10 to 20 degrees hotter than outside temperatures.
Most attic fans operate with a thermostat that automatically turns the fan on and off based on a temperature the homeowner sets.
