How to Check Laptop Temperature to Avoid Overheating

Written by Ananda Ganesha M

All technological devices will eventually experience issues, and the PC or laptop you use daily is no exception. It’s important to anticipate these problems to ensure your work isn’t disrupted.

One common issue with PCs is overheating. It's a condition where component temperatures become excessively high, leading to reduced performance. In severe cases, this can cause fatal and permanent damage to the components, requiring costly replacements.

That's why it's important to regularly monitor your PC’s temperature. Although Windows doesn’t have a built-in feature for this, you can use a free application called CoreTemp. This app not only offers a range of useful features but is also lightweight and easy to download and install on your PC.

Best of all, CoreTemp is entirely free, with no need to upgrade your account to access all its functionalities. Now, let’s dive into the steps to check your laptop’s temperature using the CoreTemp application.

1. Download and Install the CoreTemp App

The first step is to download and install the CoreTemp application. You can visit the download page by clicking this link. Then, click the Download button, as shown in the image above, and choose a location to save the setup file.

Open the download window (press Ctrl + J) and click on the setup file to begin the installation process. Follow the instructions in the installation wizard until the application is successfully installed.

Simply keep clicking the Next button, and finally, click Install. Make sure the checkbox labeled Launch Core Temp is selected, and then click Finish.

2. Monitor Laptop Temperature Level

The CoreTemp application will automatically open after installation. Now, all you need to do is monitor the temperature readings displayed on the CoreTemp interface.

The interface provides various details, such as your CPU model, the socket platform it uses, real-time CPU frequency monitoring, and much more.

However, the key section to focus on is Temperature Readings, as shown in the image above. Here, you will find several important pieces of information to understand, including:

  • Power

This indicates the power consumption level of your laptop, measured in watts. The higher the value, the more electricity your laptop is consuming. The power usage depends on the activities being performed; for example, playing resource-intensive games will significantly increase power consumption, making the laptop use more electricity.

  • Tj. Max.

This information shows the maximum temperature supported by the processor. In the writer's case, the Tj. Max, short for Maximum Junction Temperature, is listed as 105°C.

If the temperature exceeds this limit, the CPU will reduce its performance to lower the temperature, a process known as thermal throttling.

  • Core #(angka)

Depending on the laptop you’re using, you may only see Core #0 and Core #1 if you have a Dual-Core CPU, like in the writer’s case. These values represent the temperatures of each core.

Min indicates the lowest temperature recorded for a core while the application is running. On the other hand, Max shows the highest temperature recorded by the application. In addition, Load displays the percentage of CPU usage, similar to the information shown in Task Manager.

3. Enable Overheat Protection

If you’re trying to monitor the temperature to prevent overheating, it’s a good idea to enable Overheat Protection. As the name suggests, this feature will display notifications when the core temperature reaches a certain level, especially as it approaches the Tj. Max threshold.

It’s quite simple to enable this feature since it’s available in the CoreTemp application for free, with no need to upgrade or purchase a license. Just click on the Options menu and select Overheat Protection from the dropdown list.

Next, check the box for Enable overheat protection as shown above (number 1). Then, adjust the settings to your preferences (number 2).

Here, you can select Automatic, which will notify you when the temperature reaches a critical level. You can also set a specific temperature threshold or set it based on the CPU's Tj. Max.

Alternatively, you can schedule specific applications to launch when high temperatures are detected. Under the Slow down option, you can configure the laptop to automatically shut down to prevent damage from excessive heat. Don't forget to click OK when you're finished (number 3).

That's it! Now, not only can you monitor your laptop’s temperature, but you’ve also enabled an anti-overheating feature to protect your laptop’s components. Be sure to work in a suitable environment—avoid dusty or hot areas to help prevent your laptop from overheating.
