Jonsbo CR-1400E overheating in Cyberpunk 2077 Overdrive?
Amidst the neon lights of Night City, I kept getting these incredibly brief pauses. They weren't constant, but they totally ruined the immersion. My logs showed that in Overdrive mode, the CPU power would spike to 150W, and the small fin stack of the Jonsbo CR-1400E just couldn't keep up, leaving temps fluctuating between 88-94℃ and causing frametimes to jump by 10-20ms. I tried lowering the resolution, which boosted the average FPS but didn't stop the thermal stutters—a cautious approach that got me nowhere. I went into the BIOS and set a positive 0.1V fan voltage offset to force a higher base RPM at low loads and added a front intake fan to the case to fix the airflow. RivaTuner showed the frametime gaps shrink from 15-30ms down to a tight 12-16ms. The first time I bumped the voltage, the fan had a slight resonance hum at idle, but setting a minimum floor of 800 RPM killed it. Temps are now 78-84℃ and memory is holding at 58-63℃.
