The options are:
o The Early Alarm: Select this setting if you want the CPU overheat alarm (includ- ing 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.
o 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 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 immedi-
ate 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 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. The system may shut down if it continues for a long period to prevent
damage to the CPU.
User intervention: If the system buzzer and Overheat LED has activated, take action immediately by checking the system fans,
chassis ventilation and room temperature to correct any problems.
Notes:
The CPU thermal technology that reports absolute temperatures (Celsius/Fahr- enheit) has been upgraded to a more ad-
vanced feature by Intel in its newer processors. The basic concept is each CPU is embedded by unique temperature informa-
tion that the motherboard can read. This 'Temperature Threshold' or 'Tem- perature 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 informa- tion to the motherboard what its 'Temperature Tolerance' is, and not the other way around. This results in
better CPU thermal management.
Supermicro 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 (i.e., 25oC).
