Why does Dead Space Remake cause thermal throttling on PS120 SE?

Every time a giant Necromorph released effects, my CPU temperature would blast past 90°C per AIDA64, causing my FPS to tank from 80 to 40. I tried lowering the in-game graphics settings to reduce load, but while FPS rose, the temperature remained high per HWiNFO64, proving the issue was physical cooling. I used the GamePP Fan Curve Configuration to set a stepped increase between 60°C-80°C and a 100% full-speed trigger at 85°C. Core temperatures were suppressed to 76-81°C per HWiNFO64, and fan speeds stabilized at 1400-1500RPM per GamePP. It's finally a stable set
