CPU Overheat Alarm
This option allows the user to select the CPU Overheat Alarm setting which de- termines when the CPU OH alarm will be activated to provide warning of possible CPU overheat. Refer to the the next item, CPU Temperature for more information regarding PECI, DTS and other thermal features of this motherboard.
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 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 temperature reaches about +5 PECI counts 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.
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.
CPU1 Temperature/CPU2 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 gen- erally 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.
