Hardware Monitoring
This feature allows the user to monitor system health and review the status of each item as displayed.
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.
Warning! 1.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.
2.To avoid possible system overheating, please be sure to provide ad- equate airflow to your system.
The options are:
•Early Alarm: 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.
•Default Alarm: Select this setting if you want the CPU overheat alarm (in- cluding the LED and the buzzer) to be triggered when the CPU temperature reaches about 5oC 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. In both the alarms above, please take immediate action as shown below.
PECI Agent 1/2 (Temperatures)/System Temperature
Note: The following item display temperature readings for the PECI Agents and the system. These items are displayed for your reference only.
Low – This level is considered as the ‘normal’ operating state. The PECI Agent temperature is well below its ‘Temperature Tolerance’. The cooling fans and PECI Agent will run normally as configured in the BIOS (Fan Speed Control). User
Medium – The PECI Agent is running warmer. This is a ‘precautionary’ level and generally means that there may be factors contributing to this condition, but the PECI Agent is still within its normal operating state and below its ‘Temperature Tolerance’. The cooling fans will run normally as configured in the BIOS. The fans may adjust to a faster speed depending on the Fan Speed Control settings.
