I'm not as sure about AMD CPUs (and they were known for having far worse overheat behaviour back in the early 2000s) but there are plenty of stories of Intel CPUs working for many years, sitting at the thermal limits, with the (stock) heatsink not even in contact, thanks to their cheap push-pin retention mechanism.
