Fan control and presets

Fan control for your fan(s) on your Apple computer can be either

• Auto: a fan is controlled by the system automatically (Apple’s default scenario). When all fans are controlled automatically by the system the app works in monitoring-only mode.
• Custom: a fan is controlled by the app. Can be either some constant RPM value (e.g. 1500 RPM) or sensor-based control (e.g. in relation to CPU PECI sensor).

For convenience the app features fan presets that let you quickly put your fan(s) to either Auto or some Custom mode depending on your activity. You can read more about fan presets here.

When Macs Fan Control quits, it always restores all fans back to Auto (Automatic preset).
