Why does my PCCooler RT500 Digital fail to cool my CPU during heavy Raft exploration?

Exploring Raft caused my frame rate to drop from 60 to 45 FPS as the RT500 struggled with heat. Adding more fans only increased noise without solving the bottleneck. I used GamePP Hardware Sensor Page to monitor temps and reduced CPU power limit from 125W to 105W. Cinebench R23 confirmed CPU temps stabilized at 85-88C, accepting a 15% performance loss for stability.
