Supermicro SUPERO X8DTN+ User Manual page 83

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 'Tem-
perature 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

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 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 temperature increases, the fan speed will also increase for effective
system 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
confi guration or debugging. Select "Performance/PF" for better system cooling. The
PF setting is recommended for high-power-consuming and high-density systems.
Select "Balanced/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 systems with normal hardware confi gurations. Select "Energy Saving/ES"
for best power effi ciency and maximum quietness. The Options are: Full Speed/FS,
Performance/PF, Balanced/BL, and Energy Saving/ES.
Voltages Readings
The following voltage readings will be displayed.
CPU1 Vcore, CPU2 Vcore, +5Vin, +12V,V P2 DIMM, 3.3Vcc (V), and Battery Volt-
