CPU Temperature Threshold

This option allows the user to set a CPU temperature threshold that will activate the

alarm system when the CPU temperature reaches this pre-set temperature threshold.

The options are 70

C, 75

C, 80

C and 85

C. (The default setting for the Intel 5100

Series CPU is 75

C and for the 5000 Series CPU is 80

C.) (See below.)

Highlight this and hit to see the status of each of the following items:

CPU1 Temperature/CPU1 Second Core/CPU2 Temperature/CPU2 Second

Core/System Temperature

Fan1-Fan6 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. If the option is set to 3-pin fan, the fan speed is controlled by voltage. If

the option is set to 4-pin, the fan speed will be controlled by Pulse Width Modula-

tion (PWM). Select 3-pin if your chassis came with 3-pin fan headers. Select 4-pin

if your chassis came with 4-pin fan headers. Select Workstation if your system is

used as a Workstation. Select Server if your system is used as a Server. Select

Disable to disable the fan speed control function to allow the onboard fans to run

at full speed (12V) at all times. The Options are: 1. Disable, 2. 3-pin (Server), 3.

3-pin (Workstation), 4. 4-pin (Server) and 5. 4-pin (Workstation).

Voltage Monitoring

The following items will be monitored and displayed:

P12V_VR0/P12V_VR1/FSB VTT/PXH Vcore/ES2B Vcore/CPU1Vcore/CPU2Vcore/
P3V3

Note: In the Windows OS environment, the Supero Doctor III settings take prece-

dence 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.
