How to Stop a Computer From Overheating?


Overheating is one of the most critical issues one can deal with when it comes to gaming or computer devices. If you are enthusiastic about gaming, you would probably love to overclock your system as well. However, you can face overheating while doing so.

So, what can you do to stop this issue and enjoy the uninterrupted performance? If you are thinking of ways to prevent your system from heating up, you are at the right place. So, bid farewell to all your overheating problems and gear up to follow our lead.

Why is my system overheating?

Numerous reasons can result in the heating up of your system. Knowing the reason behind your system’s heating-up issue is extremely important so that you can manage the issue. Following are some most common reasons that can cause this issue.

Blocked Air Vents:

Vents that are blocked prevent air from entering the laptop. If you have too many software applications running in the background, you’re CPU and fans may become overworked. If you use your laptop, cushioning it with soft or uneven materials might obstruct the air vents and cause overheating.


The presence of viruses or malware in your system can also lead your system to overheat. Hence, if this is the reason, doing a quick scan will be vital for you.


As mentioned earlier, if you are a gamer and like to push your system’s limit with the help of overclocking, your system will be more prone to overheating. With overclocking, the system’s temperature can go as high as 90 degrees centigrade.

Defective Cooling System:

If your system’s cooling system is defective, it will not be able to vent out the heat, which can result in overheating. A defective cooling system can include defective fans, heat sinks, heat pipes, or even drying out of thermal paste.

Dust and Debris:

If your system is filled with dust and debris in it, it is more likely to get overheated. Why so? Well, dust or dirt can block the venting system of the unit, making it difficult for the unit to relieve the heat.

How to stop overheating?

If your system has been overheating lately, and you are finding ways to treat this issue, we are here to present you with the top solutions for computer overheating.

Improving the Air Flow:

In order to keep your computer from overheating, its air vents circulate cooled air within it. If you use your laptop on a soft surface like a bed or couch, its vents could get blocked. Your computer will likely cool down if you use a table or lap desk.

Additionally, desktop computers require enough ventilation to stay cool. Place your PC on a solid, sturdy surface with lots of room around it rather than keeping it in a cupboard or on a rug.

Fixing the Fans:

You might only need to wait a short while for your PC to cool down naturally if the fans are functioning. However, if your computer is hot and the fans aren’t operating correctly or are excessively noisy, it may be an indication that they are obstructed or broken. Try to clean your computer, increase the ventilation, or change the fans in such cases.

Cleaning your computer:

Cleaning your computer might help it run cooler. The airflow through your computer’s vents may be obstructed by a buildup of dust or other debris, which might lead to overheating. If you have the correct equipment, cleaning the dust and dirt from your computer’s vents and fans is not too difficult.

Cleaning out the debris that gets inside a computer may boost speed, performance, and airflow all at once. Your computer has to be cleaned if you haven’t done it in at least six months.

To remove dust from the computer’s tiny corners, plenty of users employ cotton swabs. As an alternative, several retailers provide compressed air containers for blowing out dust.

Getting the thermal paste re-applied:

In order to disperse heat and keep your PC cool, thermal paste is a substance that connects the CPU or GPU with metal heat sinks. The thermal paste on your computer may eventually dry out, especially if you often overtax it.

You must disassemble your gadget to change the thermal paste because it is housed within the computer. If you’re not an expert, ask a skilled technician to complete this. Reapplying thermal paste can help reduce heat buildup, especially on older computers.

External cooling system:

It is preferable to use your laptop on a firm, flat surface since many laptop ventilation systems suck cool air in from the bottom. Use a cooling pad that sends air upward into your laptop’s vents if it frequently overheats.

Unblocking the vents:

Your computer has fans inside to help it cool itself, and when the vents of those fans are clogged, the air cannot go through them as it should, causing your computer to overheat. Ensure that the vents on your PC have a lot of free space surrounding them. This may also apply to the surface where your computer is placed. For instance, the blanket will prevent the computer’s airflow if you use your laptop in bed as you regularly do. Use your computer on a solid, level surface so it can “breathe” for the greatest results.

Use of cooling pads:

You may get a cooling pad that effectively serves as an additional laptop fan. These often cost less than ten dollars and connect to your laptop immediately, frequently via a USB connection. Though laptop cooling pads can reduce the temperature of your computer’s exterior, they have less of an impact on the device’s interior heat sources.

Changing settings:

It might help you out if you alter your computer’s settings so that it doesn’t overheat as rapidly depending on the type of computer you have. Find out which settings on your particular computer model will give it the optimum performance. By changing these settings, you may ease the strain on your computer’s internal parts and prevent overheating.


As mentioned before, viruses and malware in your system can be a huge reason behind the overheating of your system. If you want to stop the heating-up issue, giving your system a quick scan can help you significantly.

The Bottom Line

Overheating is one of the most common issues that computer users face all around the world. However, as every other problem has a solution, there are solutions for overheating a computer as well. You can scan, clean, or even apply thermal paste to your computer so that heating issues never prevail.
