I am not a expert in these type of things. But Destiny 2 requirements are not that much. You have a better device then they requires.CS:GO is very simple in graphics even i have played that on my Core 2 Duo PC. Laptops usually have low space and does not supports that heavy load of games, that's the reason i prepare a desktop PC. After reading your PC specs i think your GPU heats up because of low PSU. I don't know what is the required PSU for your GPU because i have never used a laptop GPU. A Geforce GTX 1650 required PSU is 350 W. So you must check what is PSU of your laptop and what also check what is required for your GPU?
Yeah low settings will help to prevent GPU from being heat up. But that's not the solution.
