Fan Control

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 cor-
relative. When the CPU on-die temperature increases, the fan speed will
also increase for effective 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 configuration 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 configurations. Select Quiet to
optimize for minimal fan noise and Custom to enter user-specific settings.
The options are Quiet, Stable, Full Speed and Customize.
When Customize is selected above, the settings for CPU_FAN1 Control,
SYS FAN1/FAN2 Control will appear and can be configured.
SYS FAN control
This feature controls the system fan speed control mode. The options
are Auto, PWM mode, and DC mode.
