CPU Temperature Threshold

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

Fan 1-FAN6/Fan 7 (CPU Fan1)/Fan 8 (CPU Fan2): If the feature of Auto Fan

Control is enabled, the BIOS will automatically display the status of the fans

indicated in this item.

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

cedence 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.
