During the game, the temperature rises by 80+

During downtime or when working with programs, the temperature is 40-50 degrees. If I go into any, even a weak game, the temperature takes off by 80+. and the laptop goes into hibernation (sleep). Why does the temperature rise sharply? (The cooler is 4 years old) but in normal mode it works well. So why does the temperature soar during the game?

Change the thermal paste, clean the entire computer from dust, and change the cooler to a new one, it will work quieter and the temperature will be normal when idle from +27/37 to +40/44 in games from +65 to 75 over 80/90 think very hard and act
