Why is my notebook overheating and how to avoid it?

Overheating is a serious problem that can lead to irreparable damage. Learn why your laptop is overheating and what to do to prevent it.

One of the easiest things in life is knowing when something is wrong with a notebook. Some signs are very clear, such as louder fans, crashes and slow system, hot keyboard and blue screen. If your notebook is having these problems, it may be overheating.

Overheating can be caused by several factors, such as: dust accumulation in the air vents, dry thermal paste or overloaded use of the machine, which forces its components to work at higher temperatures.

How to know if the notebook is overheating?

In addition to feeling its temperature and noticing that there is a significant increase, another good recommendation is to pay attention to the noise made by the fans. The fans’ main function is to dissipate heat so that the temperature remains stable. In cases of overheating, the fans should work at a much faster rate than average.

If the fans hum too loud, you might want to turn off your notebook for a while and go get some water. Sometimes it is enough to clean the coolers and remove all the dust that prevents the hot air from coming out and the situation improves considerably.

Now, if the noise is not just loud, but as if there is a loose part hitting the fan, then the best thing to do is contact the responsible technical assistance or the manufacturer, if you still have warranty.

What is the limit temperature of a notebook?

The limit temperature of a notebook is 55ºC, but some models that have a video card work above that, as some GPUs work at temperatures above this mark. This demands a more efficient cooling system to be able to dissipate all the heat.

To know if your notebook is overheating, you can download a program capable of monitoring the temperature, such as HWMonitor or Real Temp. If any component is working at temperatures above 55ºC, then it is necessary to find out if it is a defect in the part or if it is overloaded.

If your notebook is suddenly shutting down after you notice the temperature rise, then your machine has reached its limit and so that its components are not completely damaged, it shuts down the entire system. This is a safety procedure of the notebook itself, which understands that your entire system can be at risk if the temperature is not reduced.

How to avoid overheating?

Turn off the notebook and remove the battery before opening it properly. Clean the fans with a cotton swab with alcohol (but very little) and remove all the accumulated dirt. This prevents hot air from clogging and consequently overheating.

To clean the air outlet and inlet grilles, the most recommended thing is to use a small vacuum cleaner. This way you prevent dust from entering the notebook, which can happen if you use a brush.

Another important point to check when you have the notebook open is the condition of the thermal paste on the processor and GPU. If it’s dry and cracked, then it’s no longer effective, so it’s time to replace it.

Never use the notebook on the bed or any uneven surface. By doing this, you close the air vents on the bottom of the notebook and this also causes overheating.

The best thing to do to ensure the maximum lifespan of your notebook is to use it on a flat surface, such as a table. To use it in bed, without compromising its functionality, you can look for a table suitable for this situation.

If overheating is a performance issue on your notebook, you can still make some changes to your system settings to try to alleviate it, such as lowering your processor clock, lowering your screen brightness, and even adjusting the overall power consumption of your notebook. machine.
