Mac notebooks comply with all temperature limits that are set in national and international safety standards. Make sure to follow the user guide instructions regarding safety and handling.
Mac notebooks have sensors that detect temperature changes inside your computer. If your Mac notebook has fans, they turn on automatically to cool critical components.

- Just so you know, the sensor this uses is the CPU Proximity temperature, which is different from the CPU PECI (overall CPU temperature) and each core's individual temperatures, that are often significantly higher than the CPU Proximity. Macs Fan Control reports CPU Proximity on my Mac as 55ºC, but CPU PECI as 63ºC – Velociround Aug 14 '20.
Fortunately, you can easily keep tabs on your PC or Mac’s CPU temperature by installing a third-party monitoring app. How to check your CPU temperature on a Windows PC.
Here are some tips to manage the operating temperature:
- Make sure that you’ve installed all Mac software updates and all current firmware updates.
- Use your Mac notebook where the ambient temperature is between 50° and 95° F (10° and 35° C). Don’t leave your Mac notebook in your car, because temperatures in parked cars can exceed this range. You should also use your Mac notebook where the relative humidity is between 0% and 95% (noncondensing).
- Use your Mac notebook on a stable work surface that allows for good ventilation. Don’t use your Mac notebook in your bed, on a pillow, or under covers.
- Don’t put anything over the keyboard.
- If your Mac notebook has ventilation openings, don't put anything into them.
- Use only Apple-authorized power adapters. Take steps to avoid overheating the power adapter.
If your Mac notebook gets warm even when it isn’t doing tasks that require intensive calculations, or if it has fans that run for a long time, use Activity Monitor to check CPU activity. Look for malfunctioning processes that can put a significant load on the CPU, and check whether Spotlight is indexing your hard drive. You might also need to reset the System Management Controller (SMC) on your MacBook.
If you use third-party apps that measure the temperature of your notebook computer, it’s important to understand that they don't measure the external case temperature. The case temperature is much lower. Never use third-party apps to diagnose possible hardware issues.
If you have issues with your Mac notebook’s operating temperature, contact Apple. Or visit an Apple Retail Store or Apple Authorized Service Provider.© Laurence Dutton/Getty Images Your computer can easily overheat when you use it on soft surfaces, like pillows and blankets - here's how to check your computer's CPU temperature.

- You can check your CPU's temperature on a Mac or PC by downloading a third-party app.
- If your CPU gets too hot for too long, your computer could shut down or stop working permanently.
- To monitor your computer's CPU temperature, we recommend HWMonitor for PCs and XRG for Macs.

If you recently upgraded your computer, you'll want to pay attention to its CPU temperature. Running your CPU too hot can burn out your components, making your computer unusable. And if you need cooling fans, you'll never know unless you check that temperature.
Fortunately, you can easily keep tabs on your PC or Mac's CPU temperature by installing a third-party monitoring app.
How to check your CPU temperature on a Windows PC
Cpu Temp Monitor For Mac
For Windows, we recommend the HWMonitor app, which is downloadable at the developer's website for free.© Emma Witman/Insider There is a paid 'Pro' version of the HWMonitor app, but you can use the free version to monitor your PC's temperature. Emma Witman/Insider
Once it's downloaded, open the .ZIP file and extract all the files inside.© Emma Witman/Insider Extract the downloaded files. Emma Witman/Insider
Launch the app. You'll see an itemized list of your computer's components, with the temperature listed beneath each. Just find the CPU - it'll be the first item on the page, listed with its model name and number - and check its temperature there.© Emma Witman/Insider Your CPU (and other components) will be listed with their model names - for instance, the CPU here is an Intel Core i7 3520M.

How to check your CPU temperature on a Mac
For Macs, we recommend the free open-source app XRG. You can find and download the app at macupdate.com.© Emma Witman/Insider Make sure your Mac meets XRG's required minimum version release and processor before you download. Emma Witman/Insider
Double-click the .ZIP file that's downloaded to unpack it, and the application icon will automatically appear in the same folder you saved the .ZIP file. You might want to move this icon to your 'Applications' folder to find it easily in the future.© Emma Witman/Insider The XRG zip file will unzip when you've opened the app, completing the download. Emma Witman/Insider
- Launch the app, granting it permission to open if your Mac prompts you with a warning about third-party downloads.
The XRG app, a slender window with a black background, should appear. You can find temperature statistics for your computer, including the CPU, in the middle portion of the window, right under the fan speed.© William Antonelli/Business Insider Your CPU's temperature and fan speed are listed by default.

You can see more in-depth data by clicking 'Window' at the top of the screen, and then selecting 'Temperature Sensors.' This will give you a readout not just for the CPU in general, but also each of its cores.© William Antonelli/Business Insider Select 'Temperature Sensors' for a more detailed breakdown of your components' temperatures.
