I'm trying to get the maximum hash possible which requires higher TDP while at the same time attempting to keep heat down.
If I have to roll back TDP because of heat then I will. Partly why I'm fishing around for heat figures and what is deemed generally good values to shoot for.
You did mind that your cards will reach their life end way earlier if you run them @100%?
I think people make up a lot of these "theories" or numbers. These cards are designed to run >70. Either way, most cards have 3-4 year warranties...
