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 tempera- ture 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 adequate airflow to your system.
The options are:
•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.
•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 immediate action as shown below.

This feature displays current temperature readings for the CPU and the System.
The following items will be displayed for your reference only:

The CPU thermal technology that reports absolute temperatures (Celsius/Fahr- enheit) 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 ‘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
