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 conguration or debugging. Select "Standard" 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 congurations. The options are
Full Speed (@100% of PWM Cycle) and Standard (@50% of PWM Cycle).
