My tj max of my 6 yrs old toshiba satellite is 105 C according to core temp. Also when i play sims 3, or sims 4 it can reach about 75°C when also 100% cpu. Its also happen since my laptop was 1 yrs old on 2015(since starting that year i turn my power plan to power saver/eco even its laggy to prevent overheat) Also many says on forum that 80°C is also fine. But iftemperature stay near to tj max with couple of hours is dangerous when gaming?
