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
temperature 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/Fahren-
heit) has been upgraded by Intel in its newer processors. Each CPU is embedded
by unique temperature information that the motherboard can read. This tempera-
ture threshold or tolerance has been assigned at the factory and is the baseline
used by the motherboard to determine which action to take during different CPU
temperature conditions (for example, increasing CPU fan speed or triggering the
overheat alarm). Since CPUs can have different temperature tolerances, the
installed CPU can now send information to the motherboard about what its tem-
perature tolerance is, and not the other way around. This results in better CPU
thermal management.
RadiSys 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 you to understand the CPU’s temperature status, instead of just seeing a
temperature reading (for example, 25°C). For more information on thermal
management, refer to Intel’s Web site.
To avoid possible overheating, be sure to 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.
