threshold. The hardcode default setting is 72
o C.

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).
