How to properly cool a laptop during hot weather/heat wave? Our tip – LaptopSpirit – Sell a laptop

…and avoid overheating without having to go into exile in the basement or in the arctic!

Since this week, temperatures have skyrocketed (up to 39 degrees!), to the point of breaking heat records and raising the specter of a new heat wave… If our bodies are suffering, our laptops can also get stressed. In this article, we share some tips and tricks to better prepare your laptop for calming heat.

Flick the fan

No doubt many have noticed that as soon as the thermometer exceeds 25 degrees Celsius, the laptop fan becomes more present. There is absolutely nothing abnormal about it, the components release heat more quickly, and therefore the ventilator has to discharge it earlier. However, if the latter tends to drift at the slightest demand, then this is undoubtedly a sign that it needs to be cleaned of dust that has accumulated over the months.

To do this, the best solution is to use a small dusting brush. Unfortunately, the process can get quite complicated with ultrabooks and other modern laptops where various components take up even smaller square centimeters, making access to the fan (extremely difficult).

Much easier and faster as you don’t have to disassemble the chassis, just use a “dry air bomb” (also called dust bomb or compressed air bomb) to blow air through the hoods. The effectiveness of course will not be the same with deconstruction in the “rules of art” but three or four strokes will be enough to remove the bulk of the dust. A small reminder, the dry air bomb should not be shaken before use and used in an upright position. Short presses (2/3 seconds in general) are preferred and allow the grenade to rest as soon as it becomes cold.

Finally, this is obvious, but the laptop’s slots should never be obstructed to ensure optimal operation while preserving the life of the internal components. Be careful, therefore, for lovers of use on the bed, with the quilt rising to the level of the keyboard …

Use a well-ventilated bra

If a cleaning session isn’t enough, you can try a well-ventilated support lotion. Count about 20 euros for an entry-level model, triple that for high-end support with built-in speakers. On average, you can expect to lose five to ten degrees (which really can’t be neglected).

Another feature, but not the least, these braces greatly improve comfort when using your laptop slung under the sofa, both in terms of placement and by keeping your thighs from the heat escaping…

In addition to the design and the number of USB ports offered, do not forget when choosing that the larger the diameter, the more it can rotate “slowly” and therefore be discreet. Amazon, LDLC,, or even Top Achat have many models.

performance restriction

Another potential solution to contain generated heat and/or noise pollution is to deliberately limit processor performance. Most computers today offer a silent profile via the manufacturer’s tool. Its purpose is to reduce the speed of the fans, which at first glance can put off when you are in a heat wave. In fact, the silent profile will limit the performance of the processor / graphics card and thus generate less heat. That’s what matters to us here.

Another solution if your laptop does not have a utility from the manufacturer, reproduce the same principle but directly under Windows. It is therefore necessary to create a power profile indicating that the maximum processor load should not exceed 80% (for example). To do this, under Windows 11, the easiest way is to press Windows key + R and then enter “powercfg.cpl” and verify that it is correct. You should then click on “Change mode settings” and then on “Change advanced power settings”.

With basic usage, for example browsing the internet or watching a video, you won’t logically notice any difference in terms of performance but you can still get a few scores (and a few minutes of autonomy in scrolling). However, keep in mind that the longer the processor is ‘constrained’, the hotter the processor will be, but it will also be less efficient.

If you have a recent laptop with a dedicated graphics card and integrated Intel/AMD chipset, check (thanks to GPUZ for example) that the latter is actually active when Geforce use is not necessary. Otherwise, force the Intel chipset to be enabled through the graphics driver.
