Laptops are one of the most essential electronic devices. Nowadays, people use computers to fulfill their needs. Students and employees alike use this smart equipment.

However, a lot of individuals still don’t know how to properly care for a laptop. If you don’t know how to care for a laptop, it will probably quickly overheat and suffer damage.

There are many reasons why laptops quickly overheat. You can read the following article to learn more. Here are the reasons why your laptop is overheating and how to fix it.

Quick Summary

In this article, we will talk about: 

  • Why do laptops heat up?
  • How do I identify if my laptop is overheating?
  • How to fix an overheating laptop?
  • Conclusion

So, without further ado, let’s get into it.

Why Do Laptops Heat Up?

The laptop heats up for one of the following reasons:

Duration of Laptop Use

The duration of time a laptop is used is the primary cause of laptop overheating. Continuously used laptops will automatically overheat due to their constant use.

Moreover, if the laptop is utilized for playing games or rendering films, of course, the laptop will work extra and the heat temperature will rise.

Blockage of Laptop Air Circulation

One of the causes of laptop overheating may also be blocked airflow on the laptop. The heat produced by the laptop CPU and then dissipated by the internal fan is removed by this circulation.

The circulation system will eventually become blocked and obstructed due to dust and grime buildup, making it unable to effectively dissipate the laptop’s heat.

Laptop Fan is Off

Broken laptop fans are the third reason for laptop overheating. Remember that one of a laptop’s most crucial components is the cooling system. Naturally, a malfunctioning cooling system will cause the laptop to soon overheat.

One of the issues that can arise with a laptop cooling system is a damaged laptop fan. This can be the result of aging or damaged parts, including wires or capacitors.

Dusty Laptop Fan

The laptop’s fan will eventually become dusty, which will impair its ability to remove heat produced by the device and serve as a cooler.

The laptop will also accumulate more dust over time if it is used frequently. Another reason could be that the laptop hasn’t been used in a while.

Dried Laptop Thermal Paste

Thermal paste is a chemical substance that is often applied as a paste between the processor’s heatsink and the chip. But it can also be used with other heat sources like highly powered semiconductors.

The thermal paste acts as an air space remover to increase the amount of heat transfer or heat dissipation.

Naturally, this thermal paste will eventually dry out depending on how long the laptop is used, which will hinder the heat transfer process.

Full Laptop Memory

The laptop might easily overheat when its memory is full. Additionally, it only makes use of one storage and one kind of hard disk. Of course, this will slow down the laptop and cause it to heat up quickly.

Wrong Laptop Position

Many individuals are unaware that improper placement of their laptops may contribute to overheating. Placing a laptop might restrict airflow, particularly if it is done on material or cloth, which will undoubtedly raise the laptop’s temperature.

A broken laptop hinge can also be brought on by improper placement of the computer, such as when it is trampled by other things.

How Do I Identify if My Laptop Is Overheating?

According to Hampshire College, a laptop’s temperature shouldn’t get above 95 degrees Fahrenheit. So, take rapid action when you sense it getting warm. If you don’t, your computer might sustain long-term harm in addition to possibly catching fire or burning you.

The following are further indications of overheating:

  • Simple operations on your laptop take longer than normal to complete.
  • Programs and applications freeze.
  • Your mouse or keyboard on your laptop stops working.
  • Your laptop shuts down unexpectedly and won’t restart for a while.
  • Unexpected error warnings that indicate the laptop is overheating start to surface.

How to Prevent Laptops From Overheating?

When your laptop overheats, it can be tough to know what to do, but ensuring that it is adequately ventilated is a wonderful place to start to prevent the need for laptop repair. 

This is how:

  • Remove anything too close to your laptop.
  • Place your laptop on a stable, flat surface, such as a desk or table, at all times. If you can’t do that, try putting a book or other substantial object underneath it.
  • If you see any debris like dirt or hair in your vents, clean them right away.
  • Work in a cool space.
  • Use a cooling pad with built-in fans to boost airflow that elevates your laptop off of the area it is resting on.
Why Is My Laptop Fan So Loud?

Why Is My Laptop Fan So Loud?

Your computer is working overtime to cool down if your laptop fan is loud. It could be caused by a buildup of dust in the fan, or maybe it’s because the air vents are blocked, such as when your laptop is on your lap or a soft surface like your bed. 

This could be a result of the way you’re using your computer. Fans may also begin to spin noisily if you have software that consumes a lot of system resources or runs continuously in the background, such as a video game or video editing program.

How to Fix an Overheating Laptop?

There are a few ways to get your laptop operating again after you’ve verified that it isn’t working.

  • Switch off your laptop, take the battery out, and unhook the cables (if possible). Until it has cooled down, you should stop using it.
  • Examine the vents and fan for debris or other indications of obstruction. These parts are typically located on the sides or underneath your laptop.
  • Your laptop’s vents can be cleaned with compressed air. It could be necessary to have your fan evaluated for other problems if it continues to struggle, make sounds, or operate at maximum speed.
  • Change the fan control settings on your laptop. This can be done in the BIOS menu if your computer is a Windows model. Users can access their fan settings using third-party power management apps as well.


After reading this article, you might now understand why the laptop heats up. 

It can be heated for various reasons. Those can be because there isn’t enough cooling, dust obstructing intake grills or exhaust ports, a clogged fan, or deteriorating thermal paste or thermal pad.
