Should I limit max power on Biostar H310MHD3 if Wuthering Waves causes VRM overheating and CPU throttling?

Every time I popped a big ultimate with massive particle effects, my frame rate would dive from 70 to 30 out of nowhere, which is honestly nerve-wracking. The Biostar H310MHD3 has basically zero VRM heatsinking, and during long sessions, temps were hitting 98℃ - 105℃, triggering an immediate thermal throttle. I tried slapping an extra exhaust fan at the top of the case, but it only dropped the ambient temp by 3℃ while the VRM stayed stuck at 95℃—a total failure of a fix. I eventually went into the BIOS and swapped the CPU power limit from Auto to a hard 65W, and set the fan curve to hit 100% at 60℃. Using RivaTuner, I saw the clock speeds stay above 3.6GHz and frame times settle between 12-18ms. I actually set the power limit too low at first and my minimums dropped to 25 FPS, so I had to nudge it up to 75W to balance performance and heat. Now the VRM sits at 78℃ - 84℃ with the fan screaming at 2200RPM. It's loud, but at least the stuttering is gone.
