ACPI BIOS should support an independent device object in the name space, and 
implement the following methods. 
 
 
3.5.12  Thermal Control 
ACPI allows the OS to be proactive in its system cooling policies. With the OS in control of 
the operating environment, cooling decisions can be made based on application load on the 
CPU and the thermal heuristics of the system. Graceful shutdown of the OS at critical heat 
levels becomes possible as well. The following sections describe the thermal objects available 
to the OS to control platform temperature. ACPI expects all temperatures to be given in tenths 
of Kelvin. 
 
The ACPI thermal design is based around regions called thermal zones. Generally, the entire 
PC is one large thermal zone, but an OEM can partition the system into several thermal zones 
if necessary.
