automatically display the status of the fans indicated in this item.
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 vise versa.
This option is to “3-pin fan” to allow the fan speed to be controlled by voltage. Select
“Disable” to disable the fan speed control function to allow the onboard fans to
run at the full speed (12V) at all the time. The Options are: 1. Disable, 2. 3-pin
(Server), 3. 3-pin (Workstation).
