I tell my customers to place a remote reading thermometer mid way in your attic and track it for a few days in the peak heat of the day. Temperature above outside air temperature in PERFECT attic is 10-15 degrees, That being said many I see are 50-65 degrees hotter than outside air. Many times this can be lowered with ventilation. Passive like ridge and soffit vents can help. Solar tube makes the best solar attic fan I have seen, 1200 CFM of air with no wiring is pretty good @$350.
