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. Select Workstation if your system is used as a Worksta-
tion. Select Server if your system is used as a Server. Select "Disabled, (Full Speed @12V)" to dis-
able the fan speed control function and allow the onboard fans to constantly run at the full speed (12V).
The Options are: Disabled (Full Speed), 4-pin (Server), 4-pin (Workstation), 4-pin (Quiet) and 4-pin
(Super Quiet).
