How to fix Thermalright PA140 thermal spikes in Tales of Arise?
During heavy particle-effect sequences when unleashing specials, my CPU temps shot from 65℃ to 94℃ in just three seconds, instantly hitting the thermal wall. While the Peerless Assassin 140 is a beast on paper, the default PWM curve is way too lazy after 80℃, keeping the fans idling at 1200 RPM while the chip was cooking. I tried enabling 'Extreme Performance' in the BIOS, but that was a disaster—temps hit 98℃ and the system just hard-rebooted. I eventually went into the BIOS and forced the fan curve to hit 85% speed at 75℃. I also reseated the cooler, tightening the screws to a precise 0.8-1.2 Nm torque range. Using HWiNFO, I saw the peak temps drop from 94℃ to a stable 78-82℃, and frame times plummeted from 22ms to a rock-steady 11ms. The fans were screaming at first, but dialing the base speed back to 40% fixed the noise. CPU power now sits between 125-140W. After a stress test, the frame times are consistently 11-13ms, though the fan noise is still noticeable under full load.
