Chapter 4: BIOS
4-19
the CPU is still within its normal operating state and below the CPU ‘Temperature
Tolerance’. The motherboard fans and CPU will run normally as confi gured in
the BIOS. The fans may adjust to a faster speed depending on the Fan Speed
Control settings.
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.
System Temperature
Fan1-Fan8 Speeds: If the feature of Auto Fan Control is enabled, the BIOS will
automatically display the status of the fans indicated in this item.
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, and vice
versa. Select Workstation if your system is used as a Workstation. Select Server
if your system is used as a Server. Select 3-pin if your chassis uses 3-pin fans.
Select 4-pin if your chassis uses 4-pin fans. Select “Disable” to disable the fan
speed control function and allow the onboard fans to constantly run at full speed
(12V). The Options are: 1. Disable (Full Speed), 2. 3-pin (Server), and 3. 3-pin
(Workstation).
Voltage Monitoring
The following items will be monitored and displayed:
VcoreA/VcoreB
+12V/-12V
+5Vsb/+5VDD
+3.3V
P1V5/CPU_VTT/Vbat
Note: In the Windows OS environment, the Supero Doctor III settings take pre-
cedence over the BIOS settings. When fi rst installed, Supero Doctor III adopts
the temperature threshold settings previously set in the BIOS. Any subsequent
changes to these thresholds must be made within Supero Doctor, since the SD
III settings override the BIOS settings. For the Windows OS to adopt the BIOS
temperature threshold settings, please change the SDIII settings to be the same
as those set in the BIOS.
