Debugging kernel_task permanently using 60%+ cpu

Hi everyone, I have a problem with my hackintosh laptop. kernel_task is permanently using 60% or more of my cpu, and I've tried a lot of things.

The problem happen with Catalina, Big Sur and Monterey and it is unpredictable. Sometimes it just stops, and sometimes I have to reboot and maybe goes away.

I've have run sysdiagnose but I don't know where to look. If you could tell me what to find I'll be grateful

Things I've tried
