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. Your Hardware Monitoring
Screen may look like the one shown on this page, on P. 4-19, or on P. 4-20,
depending on the type of CPU(s) and HW Monitoring chip you are using.
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

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