The CPU temperature usually depends on your system's applications, programs, and software. If your device's compatibility is not excellent, it can cause the system to overheat.
The computing processing unit (CPU) performs millions of tasks in a short period which can cause the processor to heat up. This is normal when the system is under pressure, but it's a sign to have a look if it happens frequently.
System overheating creates performance-related severe problems for the user while working on the laptop/computer.
Reasons for overheating of Computer/Laptop
There can be multiple reasons your system is overheating, and if not dealt with at the time, it can cause permanent damage to your PC. It is highly recommended to check the temperature at least once a few months to be on the safe side.
Here are some of the most common reasons for increased CPU temperatures:
Size of the Computer/Laptop
If you have a thinner/lighter system, you might face the overheating issue because some manufacturers remove cooling fans to reduce the system's size. Hence, owners of these computers/laptops require extra cooling accessories to cool down their system.
These types of laptops are not made to manage high loads of work, so when under pressure, it's likely that they will overheat.
Overclocking is a command-line issue that increases the temperature of your system. Overclocking occurs when a user modifies the system's processor to get more performance. It can cause overheating of the system due to the force working of the system for performance.
The increase in performance comes with a significant temperature rise. Daily monitoring of your CPU temperatures should be a must for overclockers.
PS: For a comparison between the new Intel server CPUs, have a look here.
If you have an older system, then you might face overheating issues. Overheating in older systems occurs due to the fan's dust that resists the fan's required working to cool down a system. It also results from running heavy software on the system because it may not be compatible with these software types.
It's hot outside
If your environment is hot in general, it can have an effect on your system. Don't have direct sunlight on your system. Try to keep the surrounding environment as cool as possible and always keep an eye out for the internal temperatures. This is one of the main reasons why data centres maintain a cool temperature to keep their server CPUs from overheating.
How to know if your CPU is too hot?
Your system can get heated depending on how much load it's handling. However, we have done the research and tests to show the ranges of temperatures CPUs go through.
In general usage, temperature between 40 degrees Celsius and 65 degrees Celsius is considered to be safe. This is a stage when resource usage is in low demand.
The CPU temperature can go up to 80 - 85 degrees Celsius at high resource usage. This can happen during extended gaming sessions or when rendering videos. While this temperature is fairly normal for a few minutes, it is not good for an extended period of time.
Anything above that temperature can harm the components of the system, starting from the CPU to the surrounding components.
If you experience high temperatures on a frequent basis, you should check for the problem. If temperatures reach above 90 degrees Celsius repeatedly, the lifespan of the processor will start to reduce.
CPU Temperature Monitor in Windows
There are generally two ways to get this done. You can use the inbuilt BIOS or use temperature monitoring software. We will cover both these options below.
Check out the BIOS/UEFI
Using the relevant keys, you can check your system's temperature by accessing the BIOS during the startup. Depending on the manufacturer, the keys can change. Here's a list of keys that you can use to access the BIOS during the boot-up. (If it doesn't work for you, do a simple Google search, and you will find it)
- Acer: F2 or DEL
- ASUS: F2 for all PCs, F2 or DEL for motherboards
- Dell: F2 or F12
- HP: ESC or F10
- Lenovo: F2 or Fn + F2
- Lenovo (Desktops): F1
- Lenovo (ThinkPads): Enter + F1.
- MSI: DEL for motherboards and PCs
- Microsoft Surface Tablets: Press and hold the volume up button.
- Origin PC: F2
- Samsung: F2
- Sony: F1, F2, or F3
- Toshiba: F2
To access the BIOS to check the system temperature from Windows 10, follow the steps below.
Step 1: Go to Settings from the Start Menu or use the Windows and I keys as a shortcut. (Settings option is represented as Gear icon)
Step 2: In Settings, click on the Update & Security option
Step 3: Click on recovery from the left side panel
Step 4: In the Recovery option, select Restart now below the Advanced startup option.
Step 5: Choose 'Troubleshoot' on the reboot screen.
Step 6: Select Advanced options.
Step 7: Click on the UEFI Firmware settings and restart to confirm the selection.
Step 8: Finally, the system will redirect you to the main menu of the BIOS. Find the computer/laptop's CPU temperature.
Using Open Hardware Monitor software to check CPU temp
Note: There are many PC temperature check software on the internet. We will use the Open Hardware Monitor as it is free software and shows all the information needed for this tutorial. For an alternative, you can use Core temp software.
Step 1: Download Open Hardware Monitor and install it on your system.
Step 2: Open the software by clicking on the icon seen on the toolbar. (It will automatically open once the installation is complete)
Step 3: Check the temperature statistics.
Don't be alarmed by all the information that you can see here. What's essential is the temperatures you see next to the CPU cores. You can see the current temperature under the "Value" section and the maximum temperature recorded on your processor.
How to Check CPU Temperature in Linux [Linux CPU temperature]
There is no argument that Windows is the most used operating system due to its impressive GUI. However, due to its efficient features, Linux is also one of the most preferred operating systems by developers and programming geeks. In some cases, users face overheating issues in their system, so there are different ways to check CPU temperature in Linux, and these ways are:
(For example, we have used Ubuntu Linux because it is a widely used Linux environment among developers).

The original thermal paste is suitable for a couple of years but if it's dry, consider changing it. Many users have noticed that overheating can be eliminated by replacing the old thermal paste layer with the new one. It helps a system stay cool as it prevents the transfer of heat from one component to another.
3. Buy a New CPU Cooler
In case you are facing a significant issue of overheating and not cooling down your system, you can purchase another CPU cooler or fan. It is easy to install the cooling system, and now there are liquid cooling systems with fans that can quickly eliminate the overheating issue. Consider this option only if you are 100% sure there is no other option.
4. Keep Your System Safe from Malware
Malware can be a file or software created to harm a computer. Malware can take confidential information from your system and transfer it to the malware owner. Hence, using antivirus software is essential to keep your system safe from this malware.
This malware runs in the system's background and is very resource extensive. It may cause overheating, so it is good to use antivirus to eliminate them from your system.
5. Purchase a Laptop Stand
A laptop stand offers an appropriate airflow space for your laptop to stay cooler while processing heavy applications. A laptop stand elevates your laptop to make space for airflow to keep it from suffocation. This stand also offers an excellent angle to work on it without having any issues. You can check laptop temperature before and after using the stand to see the difference.
We have included all of the required details to check CPU temperature in both Windows and Linux systems. A recap: high CPU temperature or overheating can cause multiple issues in the system. Overheating can damage the computer/laptop internally and externally; hence, it is always good to check the CPU temperature to prevent your system from unwanted overheating.
