How to Check CPU Temperature

Having an idea of the temperature of your CPU can be important for keeping your computer running at its best. If your CPU is running too hot, it can cause performance issues and even result in system damage if not addressed. So, how to check CPU temperature? In this article, we’ll discuss how to accurately measure and monitor your processor’s temperature. We’ll also provide tips on how to reduce a high CPU temperature.

What is CPU Temp?

The Central Processing Unit (CPU) temperature is an essential component of any computing system. It is the measure of heat generated by the processor and its components when running. A high CPU temp can lead to system instability and permanent hardware damage if not managed properly. To ensure optimal performance, it is important to keep an eye on your computer’s internal temperatures and take necessary steps to regulate them when needed.

To get a better understanding of the possible risks associated with high temperatures, it is necessary to know how to check your CPU temperature. There are various software programs available for free download which allow you to monitor your computer’s internal temperatures in real-time and warn you if they reach unsafe levels.

What is Normal CPU Temp?

A normal CPU temp should be within a safe range, usually between 40-65°C for modern processors. If the reading exceeds this range, then there could be potential problems with the cooling system or too much strain being placed on the processor by high-performance tasks like gaming or video editing. To identify these potential issues, users should monitor their CPU temperatures regularly for any abnormal spikes in reading.

How to Check CPU Temperature?

The simplest way to check your CPU temperature is by using the onboard software that came with your computer. Many computers have this feature built into their BIOS, and it can usually be accessed by pressing a certain key at startup.

Use the built-in system monitor:

Many operating systems include a built-in system monitor that allows you to view the current CPU temperature. For example, on a Windows 10 PC, you can use Task Manager to view the CPU temperature. To do this, right-click on the taskbar and select “Task Manager,” then click on the “Performance” tab. The current CPU temperature should be displayed under the “CPU” heading.

Use a third-party system monitor:

There are many third-party system monitor programs available that allow you to view the CPU temperature and other system information. Some popular options include HWInfo, Open Hardware Monitor, and Core Temp. These programs often have more features and options than built-in system monitors and may be more accurate in some cases.

Use the BIOS or UEFI:

If you are unable to view the CPU temperature using software, you can also check the temperature in the BIOS or UEFI (the system firmware). To do this, you will need to restart your computer and enter the BIOS or UEFI setup utility, which is usually accessed by pressing a key (such as F2 or Del) during the boot process. Once you are in the BIOS or UEFI, you should be able to find the current CPU temperature under the “Hardware Monitor” or “PC Health Status” section.

Physical Monitoring (Optional):

If you are unable to view the CPU temperature using software, you may also be able to use a hardware monitoring device to check it. If you have a device that displays the temperature of your computer’s CPU, you can check it using that.

Causes of High CPU Temperature:

High CPU temperatures are typically caused by an inadequate cooling system in the computer, such as an insufficient amount of fans or poor airflow.

Other causes might include overclocking, running non-stop intensive applications, dust accumulation in the vents, or failing hardware components like the motherboard or power supply. If your computer is frequently exposed to direct sunlight or placed near other heat sources, this could also contribute to higher-than-normal temperatures.

It’s important to regularly check your CPU temperature to ensure that it stays within safe levels for optimal performance and longevity.

How to Reduce a high CPU Temperature:

One of the easiest methods for reducing a high CPU temperature is by increasing airflow by cleaning out dust from inside the case and ensuring that all fans are running properly.

Additionally, replacing old thermal paste can help ensure better heat transfer from the processor, as well as make sure that no additional hardware is limiting airflow through your machine.

Finally, adjusting settings such as power levels and performance modes within your BIOS or OS may help reduce temperatures further.


Even with a high CPU temperature, your processor is still functioning properly. However, if the temperature continues to increase and remains constant, it may be an indication of a hardware failure.
