kernel_task using 100% is the system thermally throttling and the OS spamming NOPs to cool the CPU down

This is usually not the case.

I don't know much about CPU internals, but this sounds like bullshit to me. A NOP is still an instruction that uses a cycle - why should that cool the CPU down? The CPU frequency should get reduced to lower the power consumption and hence the temperature.

Any way to see that?
