How to Check the Temperature of Your Mac

How to Check the Temperature of Your Mac – So far in mid-2021, waves of intense heat have swept across the United States, Europe, and other regions of the globe. While individuals are the most vulnerable to hot temperatures, your Mac may be more susceptible. People can be cooled with water, but no modern Mac does so—though few have tried. When an iPhone or iPad detects that it is getting too hot, it will give you a warning before shutting down, whereas a Mac may simply shut off. If it doesn’t shut down, you’re probably running it close to its full capacity, putting a lot of extra stress on components that could fail later in subsequent seasons.

It’s one thing to know the temperature. Then there’s the question of how hot your internal components should be running. According to Apple, you should only use a Mac when the ambient temperature (the temperature around you) is between 50°F and 95°F (10° to 35°C) and the humidity is at or below 95%.

Internal components generate significantly more heat than the ambient temperature, with 100°F or 40°C being the typical minimum operating temperature in normal indoor conditions. For extended periods of time, CPUs, GPUs, ports, and other components should not exceed 192°F (89°C). When the temperature reaches 212°F (100°C), the boiling point of water at sea level, you should either figure out what energy hogs are causing your computer to work so hard or shut it down for a bit. Almost always, it’s a browser. (For further information, check at the Energy tab’s Energy Impact column in Activity Monitor under Applications > Utilities.)

Taking the temperature of the Mac

Modern Macs include an excessive number of power sensors to identify faults and adjust fan speeds in models that include them—on an M1 Mac mini, I counted 34 using one tool. With the correct expertise or software, these sensors can be monitored.

For basic temperature monitoring on some Intel Macs, you can use Terminal or a free program. Enter the following command in Terminal and hit return:

sudo power metrics —samplers SMC |grep -i “CPU die temperature”

(Note that those are double-quotes, not single-quotes.) When prompted, enter your administrative password. This will give you a constant temperature reading of the CPU. To turn off the monitoring, press Control-C. How to Check the Temperature of Your Mac

You may also download Fanny, a free program that provides a simple drop-down collection of information in the menu bar or as a notifications widget (not the most appropriate term for Mac users in the United Kingdom and other Commonwealth countries). The average CPU and GPU temperatures, as well as current fan speeds, are included in the information.

The application TG Pro ($20; on sale for $10 at the time of writing) enables detailed monitoring and fan control for every Intel Mac and M1-based Mac. For hard disks and SSDs that support the industry-standard SMART diagnostics, you can see the temperature recorded by every sensor in your Mac. Both a conventional program window and a drop-down menu bar contain information and controls. The highest port and CPU temperatures, as well as the current fan rotation, are displayed in this bar.

You can control the internal fan speed and override Apple’s settings. This includes establishing regulations for when fans should run and how fast they should sprint. If the highest temperature of any CPU parameter is at least 158°F (70°C), the app has a preset rule that rotates the blades up to their maximum rotation.
