Macs Fan Control For Mac

Your Mac comes with various temperature sensors attached to your CPU or your HDD: when certain values are met, the computer adjusts the speed of the built in fans to make sure the components will not overheat.

Although your Mac is built to take care of these adjustments on its own, you might discover that things do not run very smoothly if you are using third party HDDs or SSDs.

Macs Fan Control is a small Mac app that allows you to visualize the sensor readings on your own, and adjust the fans speed accordingly. Keep in mind that these adjustments have a serious impact on your system and that the app is intended for advanced users only.

When launched, Macs Fan Control will automatically identify all the fans available and display the readings for the temperature sensors. Via the app’s preferences window, you can choose to see the reading for a specific fan and sensor in your status bar.

The same area allows you to change the status bar icon or disable it altogether, to switch between the Celsius and Fahrenheit temperature scales, to change the interface language, and more.

Through the Macs Fan Control status bar menu you can launch the app’s main window where you can view details about the sensor readings and adjust the fans speed. By default, the fans are controlled automatically, by the system.

Double click on a certain fan, and you will be able to set up a constant RPM value, or have the system automatically increase the speed in relation to the readings of a specific temperature sensor: you can select which one via a simple drop down menu. At the same time, you must specify the start and the maximum temperature.

Macs Fan Control provides an user friendly interface for visualizing the data gathered by your temperature sensors, while allowing you to adjust the fans’s speed manually or according to certain rules.

However, note that the app has been developed for advanced users (you can overheat the system if your adjustments are not correct) and that you need the administrator password to be able to change the fans speed.
