Welcome to the macfand wiki!

macfand is a daemon that reads temperature sensors and adjust the fan(s) speed on Apple computers. macfand is configurable and logs temp and fan data to a file. macfand has 2 modes of operation for controlling a fan:

• Set speed based on temp average from all available sensors
• Set speed based on temp average from a configured group of sensors

These modes can be configured per fan, using the latter listed method is preferred for desktop machines with more than 2 fans as it allows more fine tuning for quietness or cooling performance. macfand uses profiles to provide a known working/tuned out of box experience, but allows for their presets to be overridden in the configuration file.
