Auto : The fan control operates in the bios default state up to the set temperature.

Step : determines whether the graph setting is step or linear.

Unit : You can change the unit of temperature and pwm percentage.(1, 5, 10).

Preset : Allows you to save or load the current graph's setup state.

Mode : only four names are divided, but must be set separately.Check to enable automatic fan control, select the temperature sensor to target, add the fan to control, and select from the list to display the graph, but adjust the graph accordingly.Reset : Initialize all settings and libraries.Delay(sec) : Delay time before auto-run at windows start.Start with Windows : Auto-Run at windows start.Start minimized : starts with minimal when the program runs.Fahrenheit : set the temperature to Fahrenheit.Tray icon animation : tray icon animation starts when checked for automatic fan control activation.HWiNFO : Communicated with HWiNFO to get sensor temperature and fan rpm ( Link).NZXT RGB & Fan Controller : NZXT RGB & Fan controller support.DIMM sensor : Support DIMM temperature sensor.NvAPIWrapper : Allows you to add the NVIDIA graphics card control library.LibreHardwareMonitor : You can choose whether to use the library or not, and you can choose which devices are required for control.The percentage of the fan control can be changed to simply control the pwm.(not saved).
