Today we will look at an urgent problem related to the operating temperature of your MacBook or iMac. It’s connected with fan speed and how to control it correctly.

Mac Fan Control Settings

macOS does not have pre-installed software for monitoring the cooling system, but there are three temperature sensors in the case that make it easier to control the MacBook Pro fan. If necessary, the corresponding circuits of the motherboard can increase or decrease the voltage supplied to the fans.

MacBook Pro Fan Control via TGPro

If necessary, manual configuration, you can use the TGPro app for managing fan speed. It allows you to adjust the minimum speed, create custom profiles for the cooling system and displays information about the speed of fans in the menu bar:

  • Download and install an app;
  • After installation, the snippet will appear in the top menu bar;
  • Click on it;
  • Put the speed of rotation in Manual mode and choose RPM by moving the regulator for fan.
How to Use Fan Control on your Mac?


The high system temperature of the MacBook Pro, for example is an urgent problem for most active users of Apple technology.

The main causes of system overheating are:

  • The marriage in the production of motherboards in 2012, causing an increased load on the video chip;
  • Incorrect macOS setup (or continued use of Windows on your MacBook);
  • Narrow air vents also play a role, influenced by the overall design of the MacBook Pro Unibody line and the ideology of silent, comfortable operation, which can be a serious obstacle to cooling the powerful hardware of a fast but quiet MacBook Pro;
  • If your MacBook is very hot, and the fans do not seem to rotate fast enough, you should first install the latest system updates. In OS X 10.8.3 (and later), Apple developers took care of solving the problem by including protocols in the SMC firmware responsible for the operation of the cooling system;
  • Increasing the amount of RAM will also help reduce the overall temperature of the system by reducing the number of calls to the hard drive. Replacing a HDD with an SSD, on the contrary, in some cases can lead to coolers working at higher speeds and, as a result, an increase in noise level.
