can now send information to the motherboard what its ‘Temperature Tolerance’ is, and not
the other way around. This results in better CPU thermal management.
Bull 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 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 ‘Tempera-
ture Tolerance’ has been reached (or has been exceeded) and may activate an overheat
alarm.
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 :
1. The system may shut down if it continues for a long period to prevent damage to
the CPU.
2. 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.
System Temperature : The system temperature will be displayed (in degrees in Celsius
and Fahrenheit) as it is detected by the BIOS.
Fan Speed Control Monitor
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 tem-
perature increases, the fan speed will also increase, and vice versa. Select Workstation if
your system is used as a Workstation. Select Server if your system is used as a Server.
Select “Disabled, (Full Speed @12V)” to disable the fan speed control function and allow
the onboard fans to constantly run at the full speed (12V). The Options are: 1.
Disabled
(Full Speed) , 2. Server Mode, 3. Workstation Mode.
