Hardware Health Monitor
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
determines 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 pre-
defi 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.
2. To avoid possible system overheating, please be sure to provide ad-
equate airfl ow to your system.
The options are:
The 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 predefi ned 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 tempera-
ture reaches about 5° C above the threshold temperature as predefi ned 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.
CPU Temperature/System Temperature
This feature displays current temperature readings for the CPU and the System.
The following items will be displayed for your reference only:
CPU Temperature
The CPU thermal technology that reports absolute temperatures (Celsius/Fahrenheit) has
been upgraded to a more advanced feature by Intel in its newer processors. The basic con-
cept is each CPU is embedded by unique temperature information that the motherboard
can read. This ‘Temperature Threshold’ or ‘Temperature Tolerance’ has been assigned
at the factory and is the baseline on which the motherboard takes action during different
CPU temperature conditions (i.e., by increasing CPU Fan speed, triggering the Overheat
Alarm, etc). Since CPUs can have different ‘Temperature Tolerances’, the installed CPU
