What you'll need to do is to execute the appropriate ACPI method to
assure that the fan is turned on when ACPI gets an event indicating
that the temperature has gotten too high. See section 12 of the ACPI
manual.

I hope to have some code added to our ACPI stuff soon to do
this. However, I can't make any promises.
