Alan Wake 2 has severe FPS drops on Galax H310M Warrior D4 due to VRM overload in lighting-heavy scenes. Can fan curves help?

Handling heavy ray-tracing scenes pushed my CPU to 96°C on HWiNFO, and the thermal throttling was insane, tanking my FPS from 60 down to 30—it was driving me crazy. Monitoring showed the Galax H310M Warrior D4 default fan response was way too slow, letting heat build up on the power phases. I first tried lowering the CPU power limit in BIOS, which dropped temps by 8°C but killed my 1% lows to 20 FPS, which was just a pathetic compromise. I then used the GamePP Fan Curve Config Panel to aggressively steepen the 60-80°C curve and applied a -0.05V offset to the CPU. The GamePP Hardware Sensor Page showed core temps dropping from 92-98°C to 82-88°C on AIDA64, and frames stabilized above 50.
