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
o C, 75 o C, 80 o C and 85 o C. (*See
the note below.)
Highlight this and hit <Enter> to see monitor data for the following items:
CPU1 Temperature/CPU2 Temperature/System Temperature
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 Modulation (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 the full speed (12V) at all
the time. The Options are: 1. Disable, 2. 3-pin (Server), 3. 3-pin (Worksta-
tion), 4. 4-pin (Server) and 5. 4-pin (Workstation).
CHFan 1-CHFAN8: If the feature of Auto Fan Control is enabled, the BIOS
will automatically display the status of the fans indicated in this item.
Vcore A/Vcore B: These items display the Voltage status of CPU 1 and
CPU 2.
P3V3: This item displays the +3.3V voltage status.
P5V: This item displays the +5V voltage status.
N12V: This item displays the -12V voltage status.
P12V: This item displays the +12V voltage status.
VDD: This item displays the VDD status.
P5Vsb: This item displays the voltage status of +5V Standby power.
Note: In the Windows OS environment, the Supero Doctor III settings take
precedence over the BIOS settings. When first installed, the SD III adopts
the temperature threshold settings previously set in the BIOS. Any subse-
quent changes to these thresholds must be made within Supero Doctor,
since the SDIII settings override the BIOS settings. For the Windows OS to
adopt the BIOS temperature threshold settings, please change the SDIII set-
tings to be the same as those set in the BIOS.
