Cooling System
To cool down heat generated by mainly CPU, cooling system is implemented with special power supply controller, system controller, BIOS, heat sensor on the system board and cooling fan on the back of system.
Overview of the cooling system:
When the heat sensor detect heat around CPU goes up over a certain high temperature (Temp. B), SMI is activated by the power supply controller. Then, SMI reaches CPU through the system controller. CPU generates an instruction to BIOS SMI routine, so that it will start rotating fan or make the CPU processing speed slow down. User select which action is preferable in the TSETUP. Further heat up makes BIOS SMI routine do both action. When the heat sensor detects heat down below a certain high temperature (Temp. A), the system stops rotating fan and makes CPU processing speed go back to the previous setting. If heat still continues to rise beyond a certain higher temperature (Temp. C), the system will automatically enters into AutoResume mode and machine is shut down.
Temp. A = ?? Ž
Temp. B = ?? Ž
Temp. C = ?? Ž
