During the recent heatwave in Germany, my laptop was struggling hard while gaming. The back got so hot I could barely keep my finger on it. I bought it in 2022 and had never opened it up before. Turns out the fans were packed with dust. A friend who works at a computer shop blasted everything clean with compressed air. The whole thing took about 10 minutes. Since then it's been noticeably quieter, cooler, and seems to hold its FPS much better. Apparently cleaning your laptop once every four years is a good idea.
