CPUs may run hotter but they have so much more protection. You can even power on and boot a modern Ryzen without even having a heatsink attached and it will not only survive, it will actually go in the BIOS and work for a while! One of these Socket A Athlons would be dead in a microsecond of having pushed the power button if you forgot to put on a heatsink. The Intel PIIIs of the time I believe were one of the first to implement thermal throttling and would crash but probably survive.
