Solving PA120 SE thermal spikes in Minecraft RTX
The visual punch of Ray Tracing is incredible once the performance is stable, and seeing it run properly is just satisfying. Even though the PA120 SE is a beast, the CPU temps were bouncing between 60-85℃ in RTX mode, causing the motherboard to constantly trigger boost clock switches. This made my frame rate jump erratically between 60-110 FPS. I tried the 'Silent' profile on my motherboard, which was a disaster—the noise stopped, but temps hit 95℃ and the lag became unbearable. I eventually built a custom fan curve, setting 65℃ as the trigger for full speed, and added a +0.03V offset in the BIOS to stabilize the voltage. RivaTuner showed the frame times tighten from 15-30ms down to 9-13ms. I had a couple of boot failures when I first messed with the voltage, so I backed it off to +0.02V. Now the CPU stays between 65-74℃ with fans at 1400 RPM. The performance analyzer shows the frequency is finally flat, with frame times locked at 7.2-9.8ms.
