Preventing CPU Frequency Drops
As my city population hit one million, the CPU hovered at 98℃ and the game simply crashed to desktop. I felt completely hopeless. I thought it was a MOD conflict and deleted half my plugins, but the frequency stayed stuck at 2.1 GHz per HWiNFO. I finally used the GamePP Fan Curve Configuration to set the fans to 70% speed at 60℃ and improved the case airflow. Cinebench stress tests showed frequencies stabilized at 4.1-4.3 GHz per HWiNFO, and CPU temps stayed at 82-88℃ per AIDA64. GPU temps remained steady at 65-72℃, making the city stable at 72℃
