My Biostar B550MH is overheating during Returnal's time loop combat; should I adjust the fan curves to stop the thermal throttling?

Time loop combat pushed the VRMs too hard, causing thermal throttling. BIOS fan tweaks fixed it, my back muscles finally relaxed.

Fine-tuning the thermal curve on the Biostar B550MH

I ran a side-by-side comparison for this. First, I hammered it with Prime95 for 30 minutes, and the CPU temp shot up to 88℃ - 92℃ instantly, triggering a massive downclock. I tried setting the fans to 100% in Windows, which dropped temps to 76℃ - 80℃, but the 55dB noise was like having a jet engine in my room. I went into the BIOS Hardware Monitor and set a stepped curve: 1200 RPM below 60℃, and ramping up to 1510 RPM at 75℃. OCCT confirmed the VRM cooling efficiency improved to 84% - 89%, and the noise stayed tolerable. In-game, frame variance dropped by 5% - 8%, and those heat-induced dips stopped. The only downside is the tiny heatsink on this board; if your room is over 30℃, you'll still see some temp spikes. It's just not built for absolute thermal stability.
