How to Check Your Laptop’s Temperature?

You do not want your laptop to overheat, so you need to know how to check your laptop’s temperature. We will show you the different ways that you can do this in this guide.

Your laptop has a lot of electronic components packed into a small space, and there will always be a heat buildup. Therefore, if your laptop is “running hot” regularly, you will experience problems soon.

Your central processing unit (CPU) is the most challenging working chip in your laptop and the most susceptible to overheating. Therefore, it is possible that it could fail if you do not fix an overheating problem.

By monitoring the temperature of your laptop, you can take steps to solve any overheating problems.

Does Your Laptop Feel Hot?

If your laptop is running at optimum temperature, you don’t need to check it regularly.

But how do you know this?

One of the easiest ways to check the temperature of your laptop is to touch it.

Place your hand on the surface of your laptop once it is switched on. Try different locations to see if there are any obvious heat spots.

Your laptop will always generate heat, so it is nothing to worry about if it is warm. But if your laptop feels like it is burning, then you have a problem.

Once you have identified that your laptop is overheating, you need to look at ways to check its operating temperature.

You need to know how hot your CPU and other critical components are getting, as this will affect your laptop’s performance and overall life.

Fortunately, there are several free applications that you can download and install to check your laptop’s temperature.

We will take a look at the best ones in this guide. However, even if your laptop does not appear to be running hot, it will not hurt to check the temperature occasionally.

What Temperature is Bad for Your Laptop?

There are many different laptops available that all have different specifications. So when you check the temperature of your CPU, you need to know what is good and what is wrong.

If you see that your CPU is running at 43º, how do you know if this is OK or not?

You need to know what CPU your laptop has.

Go to the website of your laptop manufacturer and look for this information.

The manufacturer may provide temperature information that will help you. If not, then you can search for the maximum temperature that your CPU can operate under.

What you are looking for here is the maximum operating temperature for your CPU. When you find this, you always want your CPU to have a running temperature below this. 

Sometimes you may see a “T junction” temperature quoted. If this is the case, you need to aim to keep your CPU running at around 30º less than this.

Some laptop owners think they can check their machine’s temperature in Windows 10, but this is not the case. Windows 10 is a great operating system, and you can do many things with it, but checking your CPU temperature is not one of them.

You will need to download a special app; let’s look at some of these below.

How to Check Temperature of Your Laptop?

1. The Core Temp Application

Core Temp is a free application that you can use to check the temperature of your laptop CPU. 

While other temperature checking apps will look at different components of your laptop, Core Temp concentrates on the most vital component, which is your CPU.

When you use Core Temp, it will tell you everything about your CPU.

You will know the CPU name, the cores that it has, and of course, its running temperature. 

Earlier, we mentioned the “T junction” temperature, and Core Temp will inform you of this.

If your CPU has more than one core (most modern laptops will have this), then Core Temp will display the temperature of each core.

With Core Temp, there is a feature where you can see your overall CPU temperature displayed in your system tray for Windows Vista and above.

2. The HWMonitor Application

If you want to know more about how your laptop essentials perform than Core Temp offers you, you can use the free HWMonitor application for Windows.

You will see comprehensive information about your CPU and the temperatures that each core runs on a single screen.

HWMonitor will also provide information about the voltages for each CPU core.

As far as CPU temperature goes, you will see the current temperature that each core is operating at and minimum and maximum temperature values.

You can see other information too with this app, which is a very lightweight and useful tool.

3. The Open Hardware Monitor Application

Another free application that will display a lot of information about your CPU and your graphics processor unit (GPU) is the Open Hardware Monitor.

The Open Hardware Monitor will provide other details, such as the speed of your cooling fan(s) and the voltages of key components.

As you would expect, you can see the current temperature of your CPU cores and overall, and there are minimum and maximum values too.

It is easy to add any of these temperatures to your system tray so that you can monitor temperatures at a glance.

There is a 32-bit and a 64-bit version of this app, and you can use it on Windows XP upwards.

4. The Speccy Application

Speccy is an excellent tool for your laptop. There is a free version of it and a premium version that provides you with more advanced information.

You will only need to download the free version to keep an eye on the temperature of your CPU and other essential components.

Just open the Speccy app, and it will tell you all of the essential information you need to know about your laptop.

You will see the CPU temperatures, your motherboard temperature, GPU temperature, and even internal storage device temperature. 

As with the other temperature checking applications, you can add different temperatures, such as your CPU.

You can open your system tray very easily and monitor this without having to open the app.

5. Using your Laptop BIOS to Check CPU Temperature

Every laptop has BIOS (basic input-output system), and you can likely see the temperature of your CPU by accessing your BIOS configuration.

Your BIOS is critical for the operation of your laptop, and we do not recommend that you change any of the settings in it, or you may find that your laptop will not work properly.

There will be a way to enter your BIOS when you reboot or start up your laptop.

As soon as your computer starts (you need to be quick), you need to press the appropriate key on your keyboard to enter the BIOS. This could be F2, F10, the delete key, and so on.

You need to check how to enter BIOS for your laptop.

Once in the BIOS utility, you will see tabs for different elements of your system.

There is likely to be a CPU tab, so use your keyboard to navigate to this. If it is available, you should be able to see the current temperature of your CPU.

Here you need to bear in mind that your CPU will not be under a lot of stress as you are not running your operating system at this point.

What can you do if your Laptop is Overheating?

If you discover from using the applications mentioned above that your CPU is overheating, you need to lower this temperature.

Your CPU will have a heat sink and cooling fan, and if your fan is clogged up with dust, this can reduce its performance. Clean your laptop regularly to prevent this.

You can purchase a cooling pad for your laptop to reduce the temperature of critical components.

A cooling pad contains additional cooling fans to keep your laptop cooler. These devices are effective, and they are usually reasonably priced.


In this guide, we showed you how to check laptop temperature. But, of course, your CPU is the most important component, and some good free apps will tell you the overall temperature and core temperatures.

Do everything that you can to reduce the operating temperature of your laptop.

An overheating laptop can fail very quickly. At best, you will notice that your machine is not performing as well as it should.

Use these simple applications to monitor your laptop’s temperature and take the appropriate action if your machines get too hot.
