What Happens When CPU Overheats? – Avoid CPU Overheating

If you are a pro game user, then definitely you will push the PC to its extreme potential to get the maximum output. But you will notice that the fans are ramping up and down frequently, the reason behind it is heating. Now one question that will arise in your mind is what happens when CPU overheats? We are going to discuss how to fix an overheating CPU. So, sip your coffee, and continue with us!

How Your PC Cools Itself

All the components of a PC produce heat in everyday usage, and it is very natural. Because with the help of the electricity, they do a particular task, and that is why heat is generated in CPU, graphics cards, PSU, PCB, memory, and many more internal components. This is why the cabinet and the motherboard are designed in such a way that heat can move out. If you find any gaming PC, you will see there are more cooling vents or airflow vents present all around the cabinet itself.  Better airflow helps the inner components to keep cool while playing games and try to manage the Thermal throttling or the CPU throttling issues.

How to fix an overheating CPU

The main component of a PC is its CPU or the Processor itself. It is always required to keep it at the operating temperature. Otherwise, you may face lagging issues, or even overheating the CPU can shut down the system. Basically, the CPU has its cooling system out of the box. When you buy a new CPU, a dedicated flat surface heatsink with an air cooler fan is bundled in the box itself to keep the CPU cool.

Those who are advanced users or pro users, use liquid cooling systems or water-cooling systems to keep their CPU cool while they are overclocking the CPU. You might have seen in social media or online content, that many of them, even use liquid nitrogen as a cooling agent to keep the very much overclocked CPU cool because they clocked their processor at 7 GHz up to 8 GHz clock speed or more than that, which is very much exceptional and highly risky to do.

Even in your normal day-to-day use, if the CPU overheats, then maybe there is some problem with the airflow vent or the stock cooler itself. Try to clean the dust and fix the issues.

The very next important component is the GPU or the graphics card, it also requires cooling all the time, and the good thing is that the cooling fan is pre-installed in it, so you don’t need to worry about this. Even nowadays, in the RAM slot, you can find dedicated heat sinks that will help you when you overclock them. NVMe M.2 SSD slots also come with a heat pad or heatsinks to keep them cool.

How to check the temperature of the Desktop/laptop?

If you want to check the core CPU temperature, then the easiest way to check is to install a third-party application that will detect it. The name of the software is Core Temp. You can easily download it from here also. 

After successful installation, you have to follow the steps. Open the application from your desktop, then locate the temperatures of the processors at the bottom of the widget. After that, go to the bottom of the taskbar and select “show hidden icons” to quickly access the temperature readings. It is a user-friendly way to check.

What is the normal temperature of the computer components?

The optimal temperature range of CPU is usually in the range of 40 degrees Celsius to 70 degrees Celsius max temperature, hard disk drives – up to 45-50 degrees Celsius, motherboard’s average temperature is up to 40-45 degrees Celsius, video cards – up to around 60 – 80 degrees Celsius. 

Why does computer overheating occur?

Heating is a normal behavior of any electronic device, but Overheating is not. It can happen for many reasons. If there is any software-related bug like some heavy application running background and uses the CPU, it is also the reason behind it. Some hardware-related problems may also create the same overheating issue, as maybe the stock CPU cooler fan port is not connected and that is why the air cooler is not working and CPU overheating, even the fan itself becomes defective that is not moving. The CPU heatsink or the cabinet air vent might be covered with dust bunnies, and that is why the hot air cannot pass through it, and the CPU overheats. 

In the case of a compact laptop, there is a very thin layer of cooling heatsink pipe that comes out from the CPU, so if we don’t place it properly, air circulation is not possible, and the CPU overheats. 

What happens when CPU overheats?

Now we are going to give the answer to the most-awaited question: what happens when CPU overheats. Excess heat is the main enemy of each electronic component. So, when a PC’s CPU overheats, the lifespan of these electrical components decreases; even excessive overheating can do irreparable damage to the product.

Blue Screen

If you can see that your machine is showing a blue screen or error messages or beep codes without any reason or in between your ongoing task, then don’t ignore it. Heat issues may be the reason for this screen death.

Random Restart

If there is any software-related issue, then your system can do frequent shutdowns with error beeps. Initially, try to find if there is any malicious software in your system or regularly update your software and security intelligence update for Microsoft defender. After doing all these steps, if the random restarts still happen, then it is a sign of overheating, the CPU becomes too hot, and that is why the system forcefully shuts down by itself. 

Getting Slow

If you are facing some slowness or lag in your daily usage, then it is a sign of overheating. These are some of the events that occur when the CPU overheats.

Frequently Asked Questions

What happens when the CPU overheats while gaming?

Ans: It becomes slow, and the frame drop will decrease drastically, and in the end, the video game becomes unplayable.

What will happen if the processor overheats?

Ans: At first, you will face some slowness or lag in the daily usage, and then the system experiences frequent shutdowns with error beeps.

Can overheating damage the CPU?

Ans: In the long term, if you don’t take any steps to keep your overheating CPU then heat can permanently damage the CPU. 

How do I know if my CPU is overheating?

Ans: You will face random restarts; the PC is getting slow day by day. These are the most common symptoms of CPU overheating. 


We have already covered what happens when CPU overheats, so if you are facing any of the symptoms from the list, then try to clean the motherboard and the cabinet to bring back the cooling efficiency in which the desktop can perform well. It will help you to improve your performance in day-to-day life.
