Chapter 7: BIOS
7-19
System Fan Monitor
This feature allows the user to decide how the system controls the
speed of the onboard fans. If the option is set to “3-pin fan”, the fan
speed is controlled based upon the CPU die temperature. When the CPU
die temperature is higher, the fan speed will be higher as well.
If the option is set to “4-pin”, BIOS will employ PWM (Pulse Width
Modulation) to control fan speed according to the Thermal Management
Settings, which may be pre-configured by the user.
Select “3-pin” if your serverboard has 3-pin fan headers. Select “4-pin” if
your serverboard has 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
and allow the onboard fans to run at full speed (12V) at all time. BIOS
will apply the chosen setting to all fan headers on the serverboard.
The options are "Disable", "3-pin (Server)", "3-pin (Workstation)", "4-pin
(Server)" and "4-pin (Workstation)".
The recommended setting for the 7034A-T/7034A-i is " 4-pin
(Workstation) ".
Note: loading the default settings into BIOS may change this setting. If
you do load BIOS defaults, you should reenter BIOS setup and change
this setting back to " 4-pin (Workstation) ", then save and exit.
