Tuning start-up voltage for Jonsbo CR-1400 ARGB in Expeditions: Rome
By the time the Expeditions: Rome loading screen finally popped up, I realized the Jonsbo CR-1400 ARGB was struggling during the boot phase. Because the start voltage was set too low, the fan didn't ramp up immediately when the CPU hit a 120W spike, sending core temps to 90℃ in 3 seconds and triggering a protective BIOS delay. I first tried increasing the boot delay timer, which just made the whole process take longer—a total waste of time. I then manually bumped the fan start voltage from 5V to 7V to ensure it hits the 1200 RPM rated speed the moment it gets power. The motherboard logs showed the boot peak temp dropped from 92℃ to 74℃ - 78℃, shaving about 4 seconds off the boot time. I noticed a slight hitch when the fans stop during shutdown after the voltage bump, but adjusting the PWM stop threshold smoothed that out. CPU temps now sit comfortably between 65℃ - 72℃. I switched the boot mode in the power management panel and it's finally sorted.
