Why is my laptop so hot: How to Cool Down Laptop

fix your overheating laptop

Laptops nowadays are getting more powerful and compact as technology advances. While the CPU and GPU performance increases, the inside of your laptop is getting more crowded by components.

Of course, the better performance also entails more heat production, which is the biggest threat in a laptop's life, apart from spilling some coffee on it.

An overheating laptop is not only a problem because it will slow your laptop down, but it can cause irreversible damage to the parts inside your laptop, that will eventually make it unusable.

In this article, we will show you how you can cool down your laptop and keep your laptop cool with a few easy tricks.

How can you tell that your laptop is overheating?

Just because your laptop is hot to touch, it doesn't mean it's overheated. The very first tell sign of an overheating laptop is sound. If the fans are constantly running on max speed, that probably means that your laptop is overheating and it's trying to cool it down.

If performance drops (because the laptop is automatically dropping down the Clock speed of the CPU to generate less heat), that can be a sign of a laptop overheating too.

What can cause a laptop to overheat?

Overheating is usually caused by insufficient cooling. This can mean that your air vents may have been blocked by dust, the fan may have been blocked by something or the thermal paste on your CPU is too old and is not transferring heat efficiently anymore.

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

First things first: clean your laptop vents and fan

The most common issue why people laptop overheats is that dust builds up in your computer, which eventually blocks the vans. This will make your laptop fans spin at a higher rate making it much louder.

If the fans can't blow out the dissipated heat from your laptops internal cooling system, because the vents are blocked, the heat will stay inside and more and more dust will begin to build up inside your laptop.

This will restrict your fans from spinning properly, resulting in more heat.

There are only a few things that you need for this fix: A can of compressed air, a screwdriver and some cotton buds.

Step 1: Take your laptop apart

First, you will need to take your laptop apart. This is usually fairly easy and if you type in your laptops brand and model name into YouTube with the word "disassembly" there will be a lot of videos that help you taking it apart.

This is an essential step as dust could be so built up on your fans that simply blowing compressed air in to your vents might not do the magic.

Step 2: Clean your laptop with compressed air

Once you have taken your laptop apart, it's time to blow out the dust that built up inside. Hold your laptop vertically use the can and make sure you blow out every part of it with air.

Make sure you keep the can vertically as well, as if you don't you might spray some propellant on your laptop or your hands which can easily freeze things.

Step 3: Clean your laptop with the cotton pads

Once you are done with Step 2, take a cotton pad and use it remove any residue or dust that the air didn't remove.

Step 4: Reassemble your Laptop

Simply reassemble your laptop again, while making sure that you have reconnected every cable on the motherboard.

Place your laptop on a flat surface

Most of the laptops have air vents on the bottom to suck in cool air. If you use your laptop on a pillow, a blanket or in your lap, you might block these air vents and prevent cool air from flowing in.

This can definitely cause your laptop to overheat, so we recommend always keeping your laptop on a flat surface.

Use a laptop cooling pad

If you still can't keep your laptop cool enough, we recommend getting a laptop coolpad. These laptop coolers are designed to generate a better airflow under your laptop, blowing more cool air straight on to the bottom of your laptop where most of the heat dissipates and into the vents.

A laptop cooler can definitely keep your laptop cool if none of the above-mentioned method work.

Get your laptop repaired

If you are already using a laptop cooling pad, but your computer still runs hot, you might want to get it repaired as the fan in it might be broken and could need a replacement.

You must remember that laptops only have one fan to keep them from overheating, so if it breaks, it will basically turn from active cooling to passive cooling.

Fixing it with a software

As a last resort, if you can't afford a new computer right now, you can keep your current one cool by lowering the performance of it.

Removing junk files can also help with performance.

This will mean that you will end up with a laptop that is much slower that you used before, but this might buy you some time to save up some money for a new one.

Conclusion

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

However, if none of them work, it might be a good sign to get a new one.
