How to know the temperature of your PC's CPU

Do you notice that your CPU temperature is too hot? If your computer starts to behave strangely, spontaneously restarting, freezing, or slowing down when you perform certain tasks, you may have an overheating problem.

And if that was not enough, if your system overheats it can cause hardware problems. Fortunately, it will be quite easy to measure the temperature at which our equipment is.

Before looking at different options for measuring CPU temperature, we are going to offer a kind of general rule that can be used to know if our equipment is working properly or have some kind of problem:

  • Below 60º: works correctly

  • Between 60º and 70º: it works fine, but begins to overheat. It would be good to check if there is a lot of dust on fans etc. and clean it

  • Between 70º and 80º: if you are not overclocking you should check that the fans are working properly

  • Between 80º and 90º: the equipment is too hot. Check if any of the fans are broken and open them to clean the dust. Some laptops when reaching this temperature (for example, in games) begin to decrease the performance. If it exceeds 85º we should be concerned.

  • Above 90º: call the fire department.

Core Temp

Core Temp is a free application for Windows that, like many other free applications, will try to install adware in our team. We will simply have to be attentive when performing the installation and uncheck all unnecessary options.

Core Temp

Once we have installed it, Core Temp will show us the temperature in the notification area of ​​the taskbar. It is a very simple program and we can quickly check the temperature of each processor core.


HWiNFO is another free option, and in this case it offers us a more information, being able to access the temperature of different components of our computer.

HWiNFO has a 'sensor mode' that allows us to easily visualize both this data and many others related to the performance of our equipment. Even better: the program allows remote monitoring from another PC on the same network.

HW Monitor

HW Monitor may not have the best interface in the world either, but the reality is that it does the job perfectly. In a few clicks we can check the temperature of the processor, graphics card, hard disk, RAM, fan revolutions, etc.

Hwpro16 Softwares

It can be downloaded for free, but if you decide to pay for the full license you will have access to a series of performance tests with which you can determine if there is a problem with your computer.

What if I don't use Windows?

If you are a macOS user, you can consult this guide in Applesfera with several free widgets. In the case of Linux, you can do it by following these steps:

  • Open the terminal and write: sudo apt-get install lm-sensors

  • Write the following command to activate it: sudo sensors-detect

  • Confirm all options with "yes"

  • Run the following command: sensors

In addition to using text commands in the terminal, we can resort to graphical programs that extract their data from the lm-sensors, such as KSysGuard:

Another option is to install I-NEX, an application that will show us a lot of information related to the components of our computer, from the type of processor to its temperature in real time.

Measure temperature in BIOS

If you do not want to install any program to check the temperature of your computer, you will simply have to access BIOS when you turn on your computer (or to UEFI, if your computer is more modern).

To do this, you will only have to press a key as soon as you restart it (usually it is usually F2, F10, F12 or Del), although there is also a way to do it from the Windows 10 settings.

Although each BIOS is different, most of them have similar characteristics. You should find the temperature in "Monitor", "System Health", "Sensor", "H / W Monitor" or "Computer Status".

Bios Health Status

In this section we will find the temperature of the processor, the speed of each fan, etc. Graphics card temperature may not appear (GPU), but to check it you can use any of the programs named above.

As we can see, measuring the temperature of our equipment is very important to achieve better performance and take care of the condition of essential components. The positive part is that there are many options to know if our computer works well or if there really is a problem that we must solve.
