Thermal impact reduction by Intentional maximum cooling period

Disclosed is a computer cooling system by intentional max period using maximum hardware capability. During the maximum cooling period, - CPU speed is lowest

- Fan power is maximum though the sound noise increase and system performance is reduced.

The user can reduce system temperature once by staring the intentional max cooling period.

Because the fan speed is restricted by noise limitation, fan speed is not set to max hardware capability value. So the cooling by fan is not enough for whole thermal solution of the present system. As additional solution
NotePC thermal is reduced by the thermal radiation from body.

Otherwise a typical hot component in PC system are CPU, graphic chip and power circuit. The temperature of these components has a lot dependency on a behavior of the running software. It means when the running program is heavy, then system temperature goes high but after heavy program is finished, the surface temperature still stays high
because thermal radiation takes time to reduce the surface temperature, In this case, a user can reduce the system temperature by intentional max cooling period as described above.

Considering of implementation This function can be implemented only by modification the program of the micro controller on system board. The max cooling period is started intentionally by user anytime or when system recognize the high temperature. There are two reason to terminate it...
