Here the user can specifies the levels the fan will be set to. They range from 0 (fan idle) to 7 (full speed), it's not necessary to use all levels. Levels must be declared in ascending order by level_number and are declared as follows:
where level_number is the level number as described above from 0 to 7,
level_min_temperature is the temperature below which the level will be decreased.
level_max_temperature is the maximum temperature beyond which the level will be increased.
level_min_temperature for the first level must be equal to 0. levl_max_temperature for the last level must be greater than 150.
An example is provided with the software.
