LM 30 Temperature: This item displays the temperature of LM30.
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 constantly run at full speed (12V).
The Options are: 1. Disable, 2. 3-pin Workstation, 3. 3-pin Server, 4. 4-pin
Workstation and 5. 4-pin Server.
