I have a ThinkPad X220 running Ubuntu 22.04. Last year it had an
overheating problem. The OS (actually the thermald daemon) slowed the
cpus down. The laptop should not overheat, but simply slow down, but
the cpu temperature will reach the critical level pretty quickly under
heavy load.

I found out the fan assembly was bad and had actually stopped working.
Replacing the assembly was not too difficult by following the Lenovo
disassembly instructions. Cost of the fan assembly was $21.60 on
Amazon. The assembly included the thermal paste for the cpu and the
graphics chip. Much cheaper than a new laptop.
