Should I tweak the PWM curve for Jonsbo CR-1400E in Nioh?
While spamming ninjutsu in complex levels, I saw my CPU temp scream from 60°C to 98°C in two seconds. It was actually kind of exciting to see if I could push the cooler to its absolute limit. The stock fan on the Jonsbo CR-1400E is way too sluggish before 80°C, so the CPU hit the thermal wall without any warning, and clocks tanked from 4.8GHz to 3.0GHz. I tried High Performance mode in Windows, but that just pushed more power and hit the ceiling faster—a bit of a frustrating trial-and-error process. I eventually set a more aggressive PWM curve, hitting 90% fan speed at 60°C, and swapped in some high-end thermal paste. In AIDA64, max temps stayed between 84-88°C, and the FPS range tightened from a wild 40-70 to a steady 55-62. I did get some slight resonance at low loads after the change, but bumping the start voltage from 0.6V to 0.8V killed the vibration. CPU power is now stable at 140W, and temps stay between 62-78°C in performance mode.
