It would be best to care for computers because they offer multiple functions and capabilities, like browsing the web or creating a file to send to your employer for work.

But what happens when we’re trying to complete too many jobs at once? The system may overheat, reducing your computer’s life and causing severe damage to essential PC components.

Looking after your computer’s health should be your top priority. Many users may take them for granted, but that’s when you get overheating problems.

Cooling down a PC isn’t difficult once you know its cause. After you’ve educated yourself on the topic, you can take measures to prevent it from happening again.

What Causes a PC To Overheat?

PC overheating happens when the internal system of the PC cannot successfully ventilate the warm air produced by parts that bring together the computer processing. PCs can overheat for many reasons, and it usually happens because of a build-up of factors over time. 

Here are some of those aspects.

  • There’s a build-up of dust on the PC’s fan.
  • You use the PC in hot weather or under direct sunlight.
  • You have too many browser tabs or applications
  • There is excessive use of applications exhausting your system.
  • There’s a virus or malware on your PC.
  • There’s system software that hasn’t been updated.
  • Some programs on your system take long to respond, draining your PC.
  • There is a blocked air vent stopping hot air from leaving the system.
  • You have fans that have failed or malfunctioned.

How To Stop Your Computer From Overheating

After outlining the causes of a PC overheating above, we will look at the ways to prevent it from overheating.

Method #1: Clean Your PC

Sometimes, stopping a PC from overheating is as simple as cleaning it. Grab a little cloth and wipe down the whole PC to eliminate all of the particles that have made their way inside.

Method #2: Ensure Your Fans Are Working

If you notice that your computer is loud and starting to overheat, the fan could have an issue. PCs that become warm and only take a short time to cool down are fine. But when the heat doesn’t go away, that’s when you’ll notice the signs. If this is the case, you should replace the fan or bring the computer to a specialist.

Method #3: Close Programs and Apps You’re Not Using

Leaving multiple open applications on your system can cause it to overheat. Shutting down applications or browser tabs that you have open that you’re not using will help prevent this.

Method #4: Download Antivirus Software and Check for Suspicious Activity

Viruses are sneaky little enemies of computer users that can make their way onto your PC if you’re not careful. They come in all shapes and sizes and can be well hidden. Download anti-virus and malware software to protect yourself from these threats.

Method #5: Use Your PC in the Shade

Sunlight will cause your PC to overheat, and the heat that meets a system that overheats quickly is not a good combination. Do your work in the shade.

Method #6: Avoid Using Exhausting Applications

Overusing your computer will cause it to overheat, so use your PC’s Task Manager to identify what’s using the most energy and end the task. 

Method #7: Update Your System Regularly 

If your system is outdated, it will have a challenging time keeping up with the processes you need to perform, eventually causing it to overheat. You should regularly update your OS and check your hardware components.

Method #8: Ensure Airflow Into Your PC

Your PC needs airflow. The best way to ensure it’s getting it is to place it on a flat surface, so nothing is disturbing the airflow. If it does begin to overheat, there’s air getting into it to cool it down.


There are eight ways to keep your computer from overheating, and you can follow a few or all of these to ensure your PC’s excellent performance.
