Does the PCcooler RT500 TC ARGB overheat in Days Gone zombie hordes? Can process priority fix it?

This cooler was basically a joke when facing massive zombie hordes; temps climbed faster than the zombies charging at me. In the city ruins, the CPU hit a wall at 98℃, and the clocks plummeted from 4.8 GHz to 3.2 GHz, turning the game into a slideshow. I tried killing every background app, but that only dropped the temp by 2℃—a complete waste of time. I eventually went into the BIOS, enabled the most aggressive cooling profile, and manually undervolted the core by 0.08V. RivaTuner showed the minimums jump from 30 FPS back up to 55-62 FPS, and that heavy, sluggish feeling finally vanished. I actually blue-screened during loading on the first try, so I had to back it off to -0.05V to keep it stable. Now the CPU stays at 82-88℃ with fans pinned at 2200 RPM, sounding like a helicopter taking off. I exported the logs to verify, and frame times are now solid at 5.1-6.4ms.
