Oops! 90° is way to hot; no wonder that the machine crashes.

How is cooling supposed to work? Well, the fan should turn on!

If your fan doesn't run on Linux but does run on Windows, maybe the ACPI
fan control does not work for some reason. Try building a kernel with

    CONFIG_ACPI_FAN=m
    CONFIG_ACPI_THERMAL=m

i.e. ACPI fan and thermal support built as modules. How does the system
work with and without these two modules loaded?

Good luck,
Arndt
