Should I switch PWM modes for Jonsbo CR-1400 in Indiana Jones?
I was shocked that a simple fan curve tweak boosted my minimum FPS by 12! Before the fix, using the Jonsbo CR-1400 during heavy physics calculations caused my CPU to swing between 82-90°C, making the clock speeds jump erratically between 3.2 GHz and 4.1 GHz. I tried a power-saving mode first, but my frames dropped to 40, which was completely unplayable. I went into the BIOS, swapped the fan profile from 'Silent' to 'Performance', and pushed the 65°C trigger point to 1800 RPM. RTSS confirmed the 1% lows rose from 35 FPS to 52 FPS, and the frame time line smoothed out significantly. I did struggle with some annoying low-load humming after the switch, but dropping the sub-40°C speed to 800 RPM killed the noise. CPU temps now sit at 68-74°C. System info confirms the mode shift worked, and frame times are now locked at 5.1-6.4ms.
