If your CPU is running at 80C, that means you don't have adequate cooling. But this is not a huge issue because Linux (and other modern OSes I assume) have internal mechanisms to slow down in order to prevent overheating. 80C is really nothing to worry about.
IMO it's hard to damage an intel CPU by running it without adequate cooling because a thermal shutdown will happen automatically at 100C.
Thermal protection is entirely built into the hardware; the OS doesn’t generally do anything. It is possible for the OS to take over running the fans, so that you can adjust the fan response curves, but if the temperature for any reason goes above the CPU’s limit (which is almost always 100°C), then the CPU will throttle itself down to a very low clock rate so that it can cool down.
This is in contrast to older CPUs where overheating them would have immediate and fatal consequences to the CPU.
