Stop CPU throttling on Jonsbo CR-1400 ARGB in Phantom Blade Zero?
Every time a complex fight starts, my FPS tanks from 90 down to 40 without warning. It's an absolute anxiety-inducing experience. The Jonsbo CR-1400 ARGB is a small cooler, and in a hot room, the default PWM mode is just too slow to react. My CPU was hitting the 95℃ thermal wall almost instantly, triggering a massive downclock. I tried lowering the graphics settings first, which gained me maybe 10 FPS, but the CPU was still hovering at 90℃+. That was a complete waste of time. I went into the BIOS and swapped the fan control from PWM to DC voltage mode, then cranked the starting voltage straight to 12V. HWMonitor showed the peak temps drop from 96℃ to around 82-88℃, and the stuttering slowed down significantly. I did notice some annoying resonance noise after switching to DC, but adding some rubber dampeners fixed that. Now the CPU stays between 78-84℃. Stress tests show the clocks aren't dipping anymore, and the controls finally feel snappy again.
