I cannot see _TC1, _TC2 nor _TSP in your `acpidump -dt' output. Further, there is no _PSV definition in anywhere, in the first place. It seems to me that your ACPI BIOS doesn't support passive cooling at all. gahr> hw.acpi.thermal.user_override: 1 gahr> hw.acpi.thermal.tz0._PSV: 80.0C I suspect that you set hw.acpi.thermal.tz0._PSV manually. Of cource, it is insufficient to make passive cooling work with your ACPI BIOS, and you need the definition of _TC1, _TC2 and _TSP as well. If you define apropreate definition of them, passive cooling will work. But, we don't provide overriding the values of them. Perhaps, modifying your ASL (`acpidump -dt' output) to add the definitions of _TC1, _TC2, _TSP and _PSV, and loading it from loader will make passive cooling work.
