I fixed the issue by lowering my BIOS from version 303 to 302. The temperatures dropped significantly. I gained access to voltage control, making the laptop feel faster, quieter, and cooler—around 55°C while plugged in and 45°C on battery. The temperature fell by about 5°C (50°C and 40°C). I think the BIOS update was the reason.
It's quite an unusual setup... I'm able to run a Cinebench MC test. The CPU stays near 20 watts at 3 GHz. If I use the fan debugging tool (MYA's version), the fans spin quickly for a few seconds, then slow down. During that time, the processor briefly jumps to 3.4 GHz and drops to about 25 watts. After that, the fans stop and the CPU returns to 3 GHz with 20 watts. The cooling performance seems manageable if the fans run fast during stress tests. If that short fan speed increase matters, adjusting it for high loads might help. However, the BIOS upgrade was quite problematic—previously my CPU was limited to 1.8 GHz even with all cores at full capacity, running hot around 80°C while editing videos.
