Ah I didn't know about that. I just created a systemd service that runs cpupower at boot.

using cpupower to limit the max cpiu frequency to 1.61Ghz fixed the thermal issues. Default was 1.8Ghz. I'll might even reduce the max to 1.42, because USB hard disk mount drops when CPU usage is too high.

I have a RK3588 (Radxa Rock 5C) system running Armbian Debian Trixie. I have the heatsink and the fan installed as well. I set the fan PWM to 255 as soon as temperature reaches 50 degrees via a systemd service. When using all 8 cores, the system overheats (>110 degrees) and eventually shuts down. For example, when compiling ffmpeg, it works fine with 'make -j6', but 'make -j8' results in a shutdown before compilation is complete. Likewise I had thermal issues when using llama.cpp. Shouldn't the OS throttle the CPU when temperature reaches high levels? I think that is not happening at the moment. Online search referred me to cpufrequtils to set a conservative governor, but it looks like cpufrequtils does not exist for Trixie. Any suggestions on how I should approach this?
