What causes laptops to overheat

Why is my laptop getting so hot? Tips for cooling

Nowadays, laptops are becoming more powerful and compact as technology advances. As CPU and GPU performance increase, the inside of your laptop becomes more and more crowded with components.

Of course, the better performance also means more heat generation, which is the greatest threat in a laptop's life, aside from spilling coffee on it.

An overheated laptop is not only a problem as it slows down your laptop, but it can also cause irreversible damage to the parts inside your laptop that will eventually make it unusable.

In this article, we are going to show you how to cool your laptop down and keep it cool using a few simple tricks.

How can you tell if your laptop is overheating?

Just because your laptop feels hot doesn't mean it has overheated. The very first sign of a laptop overheating is sound. If the fans are constantly running at their maximum speed, it likely means that your laptop is overheating and trying to cool it down.

If the performance drops (because the laptop automatically lowers the clock speed of the CPU to generate less heat), it can also be a sign of the laptop overheating.

What can cause a laptop to overheat?

Overheating is usually caused by insufficient cooling. This could mean that your vents may have been blocked by dust, something is blocking the fan, or the thermal paste on your CPU is too old and is no longer transferring heat efficiently.

The good news is that most of these problems can be fixed at home!

First things first: clean the air vents and fan on your laptop

The most common problem with laptop overheating is dust building up inside your computer which eventually blocks the vans. This will make your laptop fans spin faster and get a lot louder.

If the fans cannot blow out the heat given off by your laptop's internal cooling system because the ventilation slots are blocked, the heat stays inside and more and more dust collects inside your laptop.

This will prevent your fans from spinning properly, which will result in more heat.

There are only a few things you will need for this update: a can of compressed air, a screwdriver, and some cotton swabs.

Step 1: disassemble your laptop

First, you need to take your laptop apart. This is usually pretty easy. If you put your laptop make and model name with the word "disassembling" on YouTube, there are plenty of videos out there to help you disassemble.

This is an essential step because so much dust can build up on your fans that simply blowing compressed air into your vents might not do the magic.

Step 2: Use compressed air to clean your laptop

Once you've taken your laptop apart, it's time to blow out the dust that has built up inside. Hold your laptop upright with the can and blow out each part with air.

Make sure you hold the can upright as well, otherwise you may spray propellant on your laptop or your hands, which can freeze things easily.

Step 3: Use the cotton pads to clean your laptop

When you finish step 2, take a cotton ball and use it to remove any debris or dust that the air didn't remove.

Step 4: reassemble your laptop

Just reassemble your laptop and make sure you've reconnected every cable on the motherboard.

Place your laptop on a flat surface

Most laptops have vents at the bottom to draw in cool air. If you're using your laptop on a pillow, blanket, or in your lap, you can block these vents and keep cool air from getting in.

This can definitely cause your laptop to overheat. We therefore recommend that you always keep the laptop on a level surface.

Use a laptop cooling pad

If you still can't keep your laptop cool enough, we recommend purchasing a laptop coolpad. These laptop coolers provide better airflow under your laptop and blow more cool air directly onto the bottom of your laptop, where most of the heat is dissipated and enters the vents.

A laptop cooler can definitely keep your laptop cool if none of the above methods work.

Go for laptop repair

If you are already using a laptop cooling pad but your computer is still running hot, you may want to have it repaired as the fan inside it may be defective and may need to be replaced.

You need to remember that laptops only have one fan to prevent overheating. So when they break, it basically switches from active to passive cooling.

Fix with software

As a last resort, if you cannot currently afford a new computer, you can keep your current computer cool by reducing its performance.

This means that you end up with a laptop that is much slower than it was before. However, this can save you time to save money on a new one.


If your computer is overheating, we definitely recommend trying at least one of the methods above to keep it running cooler.

However, if none of them work, getting a new one might be a good sign.
