Macs Fan Control from CrystalIdea is a utility app that allows you to monitor your Mac’s temperature and fan speed. If the app stopped there, that would be enough to make it a useful tool for many Mac enthusiasts. But its developer, CrystalIdea Software, took it several steps further, to provide not only monitoring capabilities but also the ability to control fan speed, both directly, by setting a desired RPM, and programmatically, by setting desired speeds based on measured temperature.

  • Easy-to-use interface.
  • You can select the temperature sensor to use when you decide to take control of a fan.
  • You can set a static fan speed, or have the app use a sensor to control fan RPM.
  • It’s free.


  • Menu bar doesn’t show temperature or fan speeds.
  • App doesn’t indicate which sensors are associated with which fans. This makes it possible to select a sensor to control a fan that has nothing to do with that specific fan.
