There is a thermostat in the brain so no matter what, once that brain reaches 75C (temperature), not 75% it will just turn on no matter what. So it is a built in automatic safety net. Your brain will never self fry. No matter the setting, once it reaches 75C, it will turn on. Now with that knowledge, one can plan the lengths of their takes, or if its a loud rock concert venue, it does not matter. But one needs to test test test because all venues/studios are different in temperature.
