There is no such debug available to users. Please try to control the PSU fans as u mentioned and thank you for the suggestions regarding power limits. Maybe you could also try to play around with Set affinity and Set priority in the Task manager Details sections. You should be able to set a lower priority for CPU on the RC process and affinity should be able to limit the cores.
Also, such settings should result in the model not creating that many parts and therefore possibly even be less harmful on the power in a longer term, but I cannot guarantee so.
