CPU Overheat Alarm

This option allows the user to select the CPU Overheat Alarm setting which determines when the CPU OH alarm will be activated to provide warning of possible CPU overheat.

Warning: Any temperature that exceeds the CPU threshold temperature predeﬁ ned by the CPU manufacturer may result in CPU overheat or system instability. When the CPU temperature reaches this predeﬁ ned threshold, the CPU and system cooling fans will run at full speed.

The options are:

The Default Alarm Setting: Select this setting if you want the CPU overheat alarm (including the LED and the buzzer) to be triggered when the CPU tem- peraturereaches about 5oC above the threshold temperature as predeﬁ ned by the CPU manufacturer to give the CPU and system fans additional time needed for CPUand system cooling.

The Early Alarm Setting: Select this setting if you want the CPU overheat alarm (including the LED and the buzzer) to be triggered as soon as the CPU temperature reaches the CPU overheat threshold as predeﬁ ned by the CPU manufacturer. (See the notes on P. 4-23 for more information.)
