Solving CPU overheating on Onda 9D4-DVH for Dota 2 now?
It's honestly ridiculous that this board hits the thermal wall during a simple team fight. The stuttering makes moving my hero feel like I'm lagging in a dream. HWInfo showed the CPU temp spiking from 55°C to 96°C in less than a second, triggering a massive frequency drop. I tried Windows Power Saving mode, but that just capped my FPS at 70, which was a joke. I went straight into the BIOS and swapped the fan PWM curve to 'Aggressive,' forcing the fans to 2200 RPM once the CPU hits 65°C. Now, the peak temps are suppressed to 74°C - 80°C, and the clock stays locked at 3.6GHz. The first time I did this, the fan noise sounded like a vacuum cleaner, so I had to tune the idle speed below 50°C down to 800 RPM to keep my sanity. Heatsink temps are now 32°C - 38°C with a clean airflow path. All stress test logs are archived, and fans are steady at 1400-1600 RPM.
