1U Rackmount System
CPU Temperature
The CPU Temperature feature will display the CPU temperature status as detected by the BIOS.
System Temperature
The item displays the absolute temperature as detected by the BIOS.
CPU Temperature
The item displays the level of CPU temperature (High, Medium, Low) as detected by the BIOS. The information shown in the screen is for your reference only. (See the notes below for more information on PECI and TControl.)
o CPU Temperature Setting - Low:
When CPU PECI (Platform Environment Control Interface) count is below or equal to TControl- 100 C. (PECI
o CPU Temperature Setting - Medium: When CPU PECI count is greater than TControl - 100 C but below TControl.
o CPU Temperature Setting - High: When CPU PECI count is greater than TControl (TControl<PECI Count).
Notes:
1. According to Intel's specifications, PECI and TControl are defined as follows:
o PECI (Platform Environmental Control Interface): PECI is a bus interface that provides a communi- cation channel between Intel processor/chipset components to external thermal monitoring devices. It sends readings from the Digital Thermal Sensor (DTS) located in the processor to an external device for fan control purposes. PECI replaces the thermal diode available in the older versions of processors.
o TControl: TControl is a temperature reading from the Digital Thermal Sensor (DTS) in the CPU used for fan speed control mechanisms. It can be referred to as a trigger point to trigger a CPU Overheat/Fan Control alarm.
