Can code damage hardware?

Can random code damage your hardware when run in Real Mode? If yes, give some examples how. What happens when the ACPI tables are overwritten? Is it possible to disable the CPU fan through code, and have the CPU overheat and break, or does the BIOS have moron-proof failsafes incase someone would do that?

well i think there was an instruction called something-and-catch-fire, which was a joke about some intel instructions that could be set on a loop and just overheat the processor, it should be long fixed by now
