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 tem-
perature conditions (i.e., by increasing Fan speed, triggering the Overheat
Alarm, etc.). Since CPUs can have different ‘Temperature Tolerances’, the
installed CPU can now send information to the motherboard what its ‘Tem-
perature 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., 25°C). The
information provided above is for your reference only. For more information
on thermal management, please refer to Intel’s Web site at www.Intel.com.

To avoid possible system overheating, please provide adequate airflow to the
system.
System Temperature:
The system temperature will be displayed (in degrees in Celsius and Fahrenheit) as it
is detected by the BIOS.
Fan Speed Readings
This feature displays the fan speed readings from Fan1 through Fan8.
Fan Speed Control Modes
This feature allows the user to decide how the system controls the speeds of the
onboard fans. The CPU temperature and the fan speed are correlative. When the
CPU on-die temperature increases, the fan speed will also increase for effective sys-
tem cooling. Select “Full Speed/FS” to allow the onboard fans to run at full speed for
maximum cooling. The FS setting is recommended for special system configuration
or debugging. Select “Performance/PF” for better system cooling. The PF setting is
recommended for high-power-consuming and high-density systems. Select “Bal-
anced/BL” for the onboard fans to run at a speed that will balance the needs between
system cooling and power saving. The BL setting is recommended for regular sys-
tems with normal hardware configurations. Select “Energy Saving/ES” for best
