Some computers allow one to disable ACPI in BIOS, in this case BIOS takes ownership of thermal zones and means to correct it (fans, throttling). In case than OS does not switch to ACPI operational mode (your case), BIOS should keep ownership of all above mentioned, but as all hardware is tested with ACPI-enabled Windows, in your particular case it can be damaged without ACPI... More problems arise than OS claims to support ACPI and then does not care about thermal, this is a recipe for disaster. Regards, Alex.
