This is something that should be handled by the kernel.

On many laptops (and iMacs, ..) the cooling is simply insufficient and
it is required as part of normal operation to lower the CPU and GPU
frequency to keep the system running.

There should be ACPI tables that tell the kernel to lower the CPU
speed when a thermal zone reaches too high temperature. There might be
a bug in the tables which Windows drivers work around by consulting
their own tables (common), the thermal driver might not be loaded or
the kernel does not act on the thermal zone info. Maybe an additional
package is required to monitor and act on these thermal readings.

It is also possible that a bios update would resolve this issue on
some affected systems.

Thanks
