Fan Control
Fan Control Setting
Fan Speed Control Mode
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 for e󰀨ective system cooling. Select
"Full Speed" to allow the onboard fans to run at full speed (of 100% Pulse Width Modulation
Duty Cycle) for maximum cooling. This setting is recommended for special system
conguration or debugging. Select "Stable" for the onboard fans to run at 50% of the Initial
PWM Cycle in order to balance the needs between system cooling and power saving. This
setting is recommended for regular systems with normal hardware congurations. Select
"Quiet" to optimize for minimal fan noise and Custom to enter user-specic settings. The
options are Quiet, Stable, Full Speed, and Customize.
When "Customize" is selected above, the settings for CPU FAN1/FAN2 Control, SYS
FAN1/FAN2/FAN3 Control will appear and can be congured.
SYS Fan Control
Use this feature to set Fan Speed Control Mode. The options are Auto, PWM Mode and
DC Mode.
