Smart Fan
When the fan switch on the rear panel is set to AUTO, fans run at
different speeds based on the measured temperature.
Target Temperature indicates the temperature at which fans run at
100%. Using the default 50°C as an example, fans run at 40%
when all temperature readings are less than 25°C, and begin
ramp-up when any reading exceeds 25°C.
Fans run at 100% speed if any temperature reading exceeds 50°C
(e.g., Target Temperature).
Setting parameters are as shown.
