System Fan Monitor
Fan Speed Control Modes
This feature allows the user to determine how the system will control 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", the fan speed will be controlled by the Thermal Management
Settings pre-confi gured by the user with this setting. 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 "Dis-
able" to disable the fan speed control function to allow the onboard fans to
continuously run at full speed (12V). The options are 1) Disable, Full Speed
and 2) Server Mode.
