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: 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 5oC above
the threshold temperature as prede.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. (See the notes on P. 4-18 for more
information.)
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 concept 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 can now send information to the motherboard
regarding what its ‘Temperature Tolerance’ is, and not the other way around. This results in better
CPU thermal management.
The manufacturer has leveraged this feature by assigning a temperature status to certain thermal
conditions in the processor (Low, Medium and High). This makes it easier for the user to
understand the CPU’s temperature status, rather than by just simply seeing a temperature reading
