With these motors performance does no fall off with heat. Performance doesn't change until you get above 200 f. Then the magnets start demagnetizing which ultimately will be fatal for the motor and ESC. Heat stabilizes after 5 to 10 minutes of hard running. We pick 165 f as safe after a hard 5 minute run because temps have stabilized by then and at 165 you are not going to slip over 200. Don't go all anal on your temp sensor, mine has a plus to minus error range of over 5 degrees but it is good enough. As long as after 5 to 10 minutes of hard running you motor is less or equal 165f go drive and have fun, no worries.
