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 chas-
sis 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 fan speed control and allow the onboard fans to constantly run at full speed
(12V). The Options are: 1. Disable, 2. 3-pin (Server), 3. 3-pin (Workstation), 4.
4-pin (Server) and 5. 4-pin (Workstation).
