Top-spec computers will always shit the bed when they aren't taken care of properly (bloatware, blocked airflow, etc)

Even for the arm series macs the max cpus run way hotter and spin fans sooner than base model in general tasks. Just how those chips are designed. They aren't designed to throttle to keep temps down, they are designed to give you all the horsepower knowing you don't care about noise and heat and care about performance.
