Hardware Monitor Logic
*Note: The Phoenix BIOS will automatically detect the type of CPU(s) and
hardware monitoring chip used on the motherboard and will display the
Hardware Monitoring Screen accordingly.
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 75
o
C, 80
o
C , 85
o
C and 90
o
C. (*See below)
Highlight this and hit <Enter> to see monitor data for the following items:
CPU Temperature/CPU Second Core Temperature
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.
When this option is to 3-pin fan, the fan speed will be controlled by voltage. Select
“Disable” to disable the fan speed control function and allow the onboard fans to
constantly run at full speed (12V). 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 fan speed control and al-
low the onboard fans to constantly run at full speed (12V). 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:
Vcore /Vcc 1.5V
-12/+12V
Vcc 1.8V
+3.3V
5Vsb/5VDD
Vfsb/Vbat
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.
