Hi, Do you have any devices with 'PNP0C0B' ID in your DSDT? It's associated with fan in ACPI spec. If you have one there is a chance that you can assign it to _ALx method in thermal zone. Do the thermal zone(s) provide other trip points (i.e. passive or critical)? Also, some systems provide hardware control to the fan, so the fan turns on when the temperature high enough. Anyway, sending DSDT would help to clarify the issue. Regards.
