Notebook warming up a lot is a constant source of concern for users as reported by Forum's show. Although there are several factors that contribute to a laptop overheating, it is possible to create strategies to try to get around the problem.
In addition, a less hot PC means less power consumption and can be an important factor to extend the life of the equipment. In the following lines, TechTudo brings together software and hardware tips to lower the computer's temperature and make its use more comfortable.

How to fix via software
Check what makes your computer warm up
In the operating system, it is possible to map the processes that the notebook performs and observe the ones that are heavier. Thus, the user can identify what is overloading the computer, that is, what is forcing the processor to overheat.
In Windows, you can check through the Task Manager. Open the service by pressing "Ctrl + Shift + Esc" on the keyboard at the same time. Expand the view to "Show Details" and in the "Details" tab, click the "CPU" column to sort the processes according to what they weigh in the processor. In the "Processes" tab, you can do the same procedure, taking a more graphic view of what happens.
Note that at the time of the printscreen, the Windows malware protection service was requiring more of the processor
In the image above, note that the Windows malware hunting service was demanding more. On your computer, you can use this hint to map which software makes the machine work heavy as a way to insulate a culprit from high temperature.
Observe the information for a while until you can identify a pattern. If you find an out of the ordinary process, research the program that is causing overhead to find out if there are problems associated with its use, or even if you can remove it.
On Linux, you can use the system monitors that accompany the different distributions for the same control.
Dedicated video card? Try to always use the built-in board
Task Manager also lets you see which GPU is in action.
Nvidia's GeForce video cards and AMD's Radeon have the highest graphics performance. However, the models can also cause overheating because they use enough energy to function.
However, the dedicated graphics card does not need to be used all the time. To navigate the Internet, edit Office documents, and perform simple tasks, the integrated computer GPU - the simpler one that comes with the processor - is more than enough. Best of all, it spends much less energy and, as a result, produces far less heat.
On Windows, your drivers should be smart enough to know when it's time to wake up the dedicated video card and when it's best to go with the native GPU. When in doubt, you can check the driver apps for the cards that are in action and set policies to force one or the other.
On Linux, the process is more manual, but not so difficult to be driven on notebooks with Nvidia cards.
You can slow down the processor to prevent overheating.
Another fix that you can try is to limit the performance of your processor in the system's power settings. That way, you'll have less performance - since the CPU will be barred from reaching higher speeds - but it will also have lower power consumption (which may be interesting for your battery) and less heat.
Update your system, BIOS, and drivers
See New BIOS Versions and Drivers for Troubleshooting Overheating Problems
Another way to combat heat is with system and driver updates. But, perhaps even more importantly, be those of BIOS.
Temperature control, with monitoring by sensors scattered across the motherboard of the notebook and the system of fan drive, for example, are tasks of the BIOS. Often, some overheating problem is caused by bugs in this component that are fixed by updates. As manufacturers are not always successful in releasing the updates, it is interesting to take a look at the laptop's support page and see if it is already running with the latest version or not.
While searching for a new BIOS, you can take advantage of and check drivers that may be related to thermal control. Intel chipset drivers, including the suggestive Thermal Framework (" Thermal Framework "), are always welcome.
The undervolting will reduce the power supply to the processor, causing a decrease in performance, consumption and heat
If you know what is overclocking, now think exactly the opposite: undervolting. The process is able to provide less energy to the processor as a way to cause slowing down, as well as consumption and heat.
Not all processors benefit from the practice and the results vary greatly from case to case, just like in overclocking. Therefore, the user needs to have patience and a lot of attention with what he is doing.
In extreme situations, undervolting can lead to an expressive decrease in the house of ten degrees Celsius in temperature - which is a high number, considering the confined space and low air circulation of laptops
How to fix via hardware
In previous suggestions, we have observed methods that aim to identify and correct the heat problem through software, system tools and configurations that benefit from energy savings and lower heat generation. Now, on this topic, check out tips on what to do with your notebook hardware. It is important to note that some procedures are difficult for beginners, so it is advisable to seek professional help.
Replace the thermal grease
Thermal paste greatly increases the efficiency of heat exchange and helps lower the temperature
The thermal compound is a chemical compound that serves to create a homogeneous layer of connection between the processor lid and a heatpipe (the copper structure that conducts the heat to the laptop fan). The component is subject to wear and, when it dries, it loses its efficiency over time. Also, for starters, manufacturers tend to save money and use quality folders that are not on their computers.
On the market, there are a lot of high quality pastes that can knock down the computer temperature at margins that can exceed 10 ° C in extreme cases. Learn how to choose the best folder for your pocket and need.
When buying folders, be aware of the origin of the compound and give preference to the options that do not use metals in their composition. Although metal-containing pastes perform better, the metal may have corrosive behavior in some cases and may also cause short-circuiting in cluttered applications. It is worth mentioning that the material is pasty and may drain. Folders with compounds without metallic materials also have great performance, with the advantage of being safer for first-time sailors.
Applying thermal grease is not trivial and you should only face the procedure if you know what you are doing. Otherwise, look for professionals.
Do a thorough cleaning
Cleaning the inside of the notebook, unclogging the air inlets and outlets, is something you can try
Another care is to clean the inside of the notebook. Laptops offer very reduced air circulation spaces that refrigerate the components, and if dirt builds up, air may find it more difficult to circulate and exchange heat with heated parts.
Extreme dust can cause damage to the fan, an essential part of thermal control and air circulation.
Consider a cooling base
Bases throw more cold air so the computer has better heat exchange capacity
This is not an ideal option because it involves using an accessory that will take a USB port from your laptop and may compromise portability. Despite this, the tip may be the outlet for those who do not find another solution to heating problems.
Good bases improve air circulation and allow your computer to be more efficient. Equipment should lower the temperature without the need for more drastic interventions, such as heat exchange, or performance sacrifices.
