Why is my Thermalright PA120 V3 struggling in BioShock 4?
While scanning large areas, I noticed my CPU temps spiked from 62°C to 94°C in just ten seconds, causing my clock speed to tank from 5.1GHz to 3.4GHz. The Thermalright PA120 V3 dual-tower setup should handle this, but the default thermal logic is way too sluggish for these transient power bursts, leading to frame time spikes of 40-60ms. I first tried slamming the fans to full speed in the BIOS; while temps dropped to 82°C, the resonance noise made my entire chassis shake—completely unbearable. I eventually went back into the BIOS to redefine the step frequency, forcing the 75°C trigger point from 60% up to 85% and slashing the fan start delay from 2 seconds down to 0.5 seconds. Monitoring via HWInfo, my core temps stabilized between 74-81°C, and frame times tightened up to a consistent 14-18ms. I did hit a snag where the fans kept ramping up and down erratically at low loads with the 85% setting, but tweaking the hysteresis to 0.8 seconds fixed the jitter. The heatsink surface stayed around 42-46°C. After a stress test, the frame times remained rock steady at 14-18ms.
