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
predefined by the CPU manufacturer may result in CPU overheat or system
instability. When the CPU temperature reaches this predefined threshold, the
CPU and system cooling fans will run at full speed.
The options are:
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 predefined by the CPU
manufacturer.
The Default Alarm
: Select this setting if you want the CPU overheat alarm
(including the LED and the buzzer) to be triggered when the CPU temperature
reaches about 5
o
C above the threshold temperature as predefined by the CPU
manufacturer to give the CPU and system fans additional time needed for CPU
and system cooling.
CPU Temperature
The CPU Temperature feature will display the CPU temperature status as detected
by the BIOS:
Low
– This level is considered as the ‘normal’ operating state. The CPU temperature
is well below the CPU ‘Temperature Tolerance’. The motherboard fans and CPU will
run normally as configured in the BIOS (Fan Speed Control).
User intervention: No action required.
Medium
– The processor is running warmer. This is a ‘precautionary’ level and
generally means that there may be factors contributing to this condition, but the CPU
is still within its normal operating state and below the CPU ‘Temperature Tolerance’.
The motherboard fans and CPU will run normally as configured in the BIOS. The
fans may adjust to a faster speed depending on the Fan Speed Control settings.
User intervention: No action is required. However, consider checking the CPU
fans and the chassis ventilation for blockage.
High
– The processor is running hot. This is a ‘caution’ level since the CPU’s ‘Tem-
perature Tolerance’ has been reached (or has been exceeded) and may activate
an overheat alarm:
