Why is my Asus laptop overheating

Previously, we have discussed why Asus laptops crash, don’t turn on, are slow ... Today, we will go over why they can overheat.

Over the years, consumer electronics have gotten smaller as have their components, which are designed for increasingly thin and light laptops ... but the voltage has remained the same.

designed for increasingly thin and light laptops

Laptops are particularly sensitive to high temperature which will cause slowdowns and in the long run will cause components to be worn out prematurely, abnormal fan noise and repeated system crashes.

What are the factors that lead to overheating and how to avoid them? We will explain it all in this article!

Avoid overheating: the performance of Asus laptops

The new models of Asus laptops incorporate two side fans with two air outlets on each side or at the back. One fan is dedicated to cooling the CPU and the other is dedicated to cooling the GPU (graphics card), which vastly increases the cooling capacity for fragile components.

Thus, you will have fewer overheating problems!

The shape and appearance of the air outlet (exhaust) for some models (like the UX series) are hidden for aesthetic reasons: ventilation is therefore an integral part of the computer's bottom case.

How can I prevent my PC from overheating?

Place it on a flat surface and in the shade

It is strongly recommended to use a laptop on a flat and rigid surface, such as a desk or table ... Avoid placing it on your lap, a bed or even a blanket layed out on the grass: the heat dissipates poorly on these surfaces and materials.

An external ventilation system equipped fan that is placed under the computer raises your laptop of the surface will optimize the dissipation of heat and improve performance.

If you have decided to work outside on a nice day, avoid leaving your computer in direct sunlight, preferably leave it or use it in the shady and well ventilated place.

Beware of dust getting into your computer

A constant and formidable cause of overheating in a laptop is dust and, to a lesser extent, long hair or tar from cigarettes.

It is recommended to use a dry air spray once or twice a month: you just have to insert the spray straw into the air vents (ventilators, ports and keyboard) of your computer in order to clear the dust lodged inside.

Use the dry air spray rather than a vacuum which could damage your computers fragile components or keyboard, even at its minimum power setting.

Avoid unnecessary programs and applications

Software can also cause your PC to overheat. Make sure that you don't have a multitude of useless and resource heavy programs that launch at startup. Many programs tend to put a heavy strain on the computer's resources when it is turned on.

So consider removing these programs to reduce the workload of the processor and avoid unnecessary overheating. You should also close all internet windows that you are not currently using, this will prevent memory (RAM) from being overused without reason.

You can see in the image above that Firefox uses most of the of the memory ( 80%), because a lot of internet tabs are active in the session. There are also 130 processes running in the background, which is far too many when starting up a computer.

Change the thermal paste of the computer

If you are well versed in computer repair, you can change the thermal paste.
A thermal paste is used to transfer the heat generated by the processor via the heat sink which is then evacuated thanks to the fan. To remove the old paste, all you need is a cotton swab and alcohol, then you can replace it with new paste (the size of a grain of rice).

Don't keep your laptop permanently plugged in

If you use your laptop exclusively at home, we also recommend that you plug it in without the battery being switched on. Indeed, a continuously connected laptop PC tends to heat up the battery unnecessarily and damage it more quickly.

If the battery of your laptop is housed under the bottom case, you should run your laptop on the battery power rather than plugged in, even though the latest models of laptops are designed to avoid overheating of the battery better than the old models with detachable batteries.

How to detect the temperature of my PC?

There are several tools to monitor the temperature of your laptop components.

SpeedFan : This very specific application that allows you to control the speed of the various fans in the computer based on the temperature of certain components.


Open Hardware Monitor : This small free software allows to monitor the temperature, the use, the frequency as well as the speed of the fans of several components of the PC.
