Heatwave: How to avoid overheating your laptop or Mac?

For a laptop, Mac or even PC game, the most critical issue is heat. Electronic components work better and last longer if the ambient temperature is relatively cool. We explain how to avoid overheating of your machine.

You’ve probably noticed that as soon as it starts to get hot, your laptop fan blows. This is definitely not abnormal, portable components dissipate heat faster, so the fan needs to evacuate it sooner. However, if your laptop tends to overheat at the slightest touch, there are a few tips that will help you dampen its heat.

Why does my laptop get hot

Laptops contain delicate, expensive and sometimes high-tech parts. These parts create almost all the heat when your computer is turned on. If it overheats too much, it reduces performance (CPU Thermal Throttling) and may even cause your PC to crash as BSODs (when your screen turns completely blue). This is also accompanied by incessant noise from the fan blowing at full power, to regulate all that.

In addition, the components used in a laptop or Mac are miniaturized (hard drive, memory, graphics card, etc.), and the ventilation circuits are smaller than those found on a desktop computer (or not even present on devices like the MacBook). Air, but its ARM chip does not heat up much compared to an Intel chip).

How to prevent your computer from overheating

Whether you are a gamer or a regular user, be aware that the components of your laptop will be subject to overheating if you do not monitor their temperature. To help you avoid this, here are some practical tips:

  • The first thing to do is see where your PC or Mac fan is located. Is it a particularly hot place? Make sure your laptop is not located near a window with direct sunlight. Sometimes moving your laptop can help reduce its temperature.
  • Dust is often the cause of overheating in any electronic device as it is sucked into the fans and accumulates inside. This dust then clogs the aeration and ventilation circuits. In addition, dust makes it harder to dissipate heat and tends to heat up electronic components more. Remember to dust your laptop regularly. You can use a can of compressed air for this purpose or a small brush with soft bristles to dust.
  • Monitor the temperature of your laptop using any free software such as speedfan. You will be notified as soon as the temperature of your laptop rises.

  • Close applications that use multiple resources. To do this, you can look at the task manager and filter the processor tab. Avoid applications and video games that load your graphics GPU a lot (we see you playersElden Ring).
  • One of the many benefits that a laptop provides is being able to work anywhere in the house: on a desk, on a bed, in the garden, in the sofa, etc. While using the PC on a sofa or on a bed , we usually put our computer on our lap. In very hot weather, this practice should be strongly avoided.

How to cool your laptop

Keeping your PC as cool as possible helps prevent overheating. This benefits them for several reasons. First, it limits Thermal Throttling (frequency scaling of a component), and second, it potentially achieves a performance boost. This also reduces the noise from the fans, which will start less frequently and less loudly. Finally, you increase the life of the components on the laptop, as it will rarely reach high temperatures. Here are some tips for cooling your laptop:

  • You can invest in a ventilation accessory. This support is connected via the USB port. It is equipped with several fans that cool your device quickly, limiting unpleasant sounds. This accessory comes in all sizes and is compatible with many PC brands.
  • Avoid using your laptop on your bed, as this may cause your device to overheat when it comes in contact with the fabric. Be aware that fibers tend to store heat and reflect it back to your device, which can become hot and damaged. So always make sure to use your computer on a surface made of hard, flat material, such as a table or a special portable stand.
  • At home (and even in the office), do not leave your computer connected to its charger all the time when using it. This will not only degrade your battery but will also promote heating.

Finally, keep in mind that if you have too many programs open at one time, your computer will overheat. Ideally, you should close unused tabs, because if you use too many sites at once, your laptop will start to get saturated. It will be slower and slower and it will eventually crash down. It is also necessary from time to time to think about turning off your laptop and letting it rest. Some people have the bad habit of letting their laptops run even at night.
