Calibrating Jonsbo CR-1400E thermal performance for Forza Horizon 5
At 350 km/h, my CPU hit 93°C in about 12 seconds. I seriously wondered if the Jonsbo CR-1400E was trying to double as a space heater. Those micro-stutters from throttling are a total nightmare for a racing game. I first tried setting the fans to 'Full Speed' in the BIOS, but the noise was like a damn helicopter taking off in my room—totally unbearable. I ended up taking the whole thing apart, applying a high-conductivity paste, and manually setting the PWM curve to start at 55°C and hit 100% at 80°C. After an AIDA64 stress test, the temps settled from 90-96°C down to 74-80°C, and the FPS drops vanished. I actually under-applied the paste the first time, which left Core 3 running 6°C hotter than the others, but a second attempt fixed the spread. Now the fans stay between 1600-1800 RPM and CPU load sits around 60-70%. I exported all the logs to a CSV just to be sure, and the RPMs are rock steady now.
