Comment (by tqh):
Windows (and often Linux) install hw specific drivers for fan control.
Haiku doesn't, as it is a huge undertaking, so it relies on ACPI and EC to
handle it. In almost all ACPI specs it is requirement that ACPI does
handle fan control unless OS takes over so not sure if I'd trust this
manufacturer.
If fw upgrade doesn't fix things I think your hardware is very unlikely to
run Haiku well. You can try to figure out what drivers control CPU/fan in
Linux and it might be possible for you to port those over.
