How to stop Jonsbo CR-1400 ARGB from throttling in Manor Lords?
Once your village hits the mid-to-late game, the sheer amount of physics calculations for buildings sends CPU load skyrocketing, causing these rhythmic micro-stutters. I found the Jonsbo CR-1400 ARGB's stock fan profile is way too lazy, only hitting 1200 RPM at 70°C, which let my cores peak between 88°C - 94°C and trigger the motherboard's thermal throttling. I first tried capping the processor state at 99% in Windows, which dropped temps by 4°C but tanked my 1% lows from 45 FPS to 32 FPS—a total performance disaster. I eventually dove into the BIOS, switched the fan curve to an aggressive profile to force 1800 RPM at 65°C, and set a negative voltage offset of -0.050V. Monitoring via RTSS showed frame times tightening from a wild 15-40ms swing down to a consistent 11-18ms. It wasn't a smooth ride; my first voltage tweak caused a BSOD during the loading screen, and I had to nudge the offset back to -0.020V to get it stable. Now, temps sit comfortably between 72°C - 78°C, and the frame delivery is finally smooth.
