How do I fix the Huntkey Blizzard T400 Snow overheating in FF XV?

My CPU spiked to 85°C per AIDA64 during combat in Final Fantasy XV, causing screen tearing. I tried maxing out the fan speed, which just increased noise to 55dB without helping. I needed a smarter curve. I used the GamePP Fan Curve Configuration Panel to switch from default to linear and enabled High Performance. AIDA64 showed temps dropping to 72°C. This finally switched my system to a stable, cool state.
