Best Solution for computer overheating and shutting down. The overheating of a PC is a phenomenon that directly affects the proper functioning of our equipment. It causes errors, data loss, locks, restarts and / or shutdowns, reduces the useful life of the components and in extreme cases irreparable damage to some of them.

We are in full August, summer in the northern hemisphere and in areas like the center and south of the Iberian Peninsula, we suffer temperatures between 35 and 40 degrees daily. Although a PC is prepared to operate at high temperatures and has controls to limit its impact, our computers also suffer from high temperatures and it is a good time to check how much they can harm them.

Keep it clear, everything inside a PC generates heat. The cooling of a computer has become an art especially in enthusiastic range teams that use overclocking techniques and squeeze the performance of components such as CPU and GPU, thereby increasing operating temperatures. We are not going to reach this much in this article but we are going to review a few common tasks that should be part of the usual maintenance, any user can perform them and effectively prevent overheating of a PC.

Check and control the temperatures of a PC

It is convenient to start the process by checking the actual temperature of the main components of our equipment, CPU, GPU and storage units, as well as that of the chassis as a whole. There are many free tools that offer us the information we need, such as  Speccy,  PC Wizard  or  HWMonitor , which record temperatures, voltages or fan speeds that ultimately form the set to consider. As a reference to take into account, the maximum operating temperature of a CPU should be between 70 and 80 degrees, although in a standard equipment is easy to keep it much lower.

Motherboard manufacturers also offer this type of information in their desktop tools and in an increasingly complete UEFI BIOS.


Dust accumulates on any PC no matter how modern it is, desktop or laptop. It obstructs ventilation ducts, reduces the efficiency of the fans and even stops them. Regular cleaning can help maintain a correct flow of cooling air. The following image is a time bomb and you would be surprised to know the large number of computers in that state (and worse).

In a desktop PC cleaning is very simple . Once the equipment is turned off, the power cable is disconnected and static electricity is discharged, we open the chassis and proceed to clean it. Aspirating or blowing gives good results although the ideal is to use a can of compressed air, isopropyl alcohol and microfiber cloths for a complete cleaning.

Personally, I disassemble every single time each and every one of the components, clean and reassemble, with special attention to CPU and GPU fans, power supply and those of the chassis. A trick to keep in mind is to hold the blades of the fans when we apply the compressed air. If they turn “crazy” they will make you an annoying noise for life.

In a laptop the complete dismantling is not available to all users but at least we must remove the outer covers and apply the compressed air to free of dust all the ventilation grilles.

The main cause of automatic shutdown in a laptop is the overtemperature. There are cooling bases for laptops and they give good results but everything starts with a good cleaning. Its use on flat surfaces reduces the temperature and if you use it on a desk, lifting it to favor ventilation is a trick that continues to give results.

CPU cooling – GPU

The microprocessor is the heart of our equipment and a good cooling system (of course, as clean as possible) is essential to maintain a correct temperature.

The fan model also matters. Intel and AMD offer fans-dissipators in the retail sale of many of their CPU models (not all). They are sufficient for a basic use but as soon as you intend to overclocking or you are a somewhat more demanding user, you will have to go through the box and buy a third-party model.

The air cooling is the most common but systems of liquid coolinghave spread in recent years as increased supply and set prices. It is a great option because in addition to maintaining low temperatures, its noise level is usually very low. Almost all systems are sold with all the necessary elements included, fans, radiator or liquid. There are real integrated wonders that cover the cooling of all the components.

In consumption we do not need so much . There is a good offer with not excessively expensive prices of liquid systems for CPU, GPU or chassis. Whether you bet on them or use air fans, make sure you have enough space in your tower to mount it.

Special mention for the change of thermal paste . It is a compound that facilitates the transmission of heat between the package of the processor and the fan heatsink. A quality thermal paste will improve that transmission and help maintain low temperatures. You do not have to do it as often as cleaning but every once in a while try to replace it.

The paste is ineffective when a small amount is applied and also when a lot is applied. Use the “pea” method. A drop in the middle of the die is enough. The natural pressure of the dissipator will spread it evenly over the entire surface.

The dedicated graphics cards are another care. They include their own dissipation-cooling system and should be removed from their PCIe slot and thoroughly clean their fans. The big manufacturers offer applications for their control and configuration, being able to customize their speed according to the reached temperature. If you are going to give good cane or mount multigraphic systems, you can evaluate the purchase of external cooling systems for GPU.

Fans – Air flow – Wiring

The effective surface (size in mm) and the speed of rotation, are measures that define the efficiency of the fans for the chassis that should also be checked and cleaned. Finding the balance between the noise emitted and the speed to keep the chassis and components “cool” is the objective. Applications like SpeedFan   allow to modify the speed of rotation of the fans, something that we can also do in the applications of the manufacturers of plates and in the UEFI.

It depends on the possibilities of your tower but there are times when strategically placing a quality and good size fan (120 mm) is enough to keep the temperature of the chassis at bay, keeping the proper air flow in step.

We talk about chassis and as always, we recommend balancing the budget in the creation of a PC. There are users who spend a lot of money on a simple graph and do not invest 60 euros in a good tower that will last for many years. There are repeated cases in support services where the questions “I do not catch the graph” abound. To kill us. You know, a good tower allows to install all our components in a solvent way, is prepared for future updates and ensures a correct air flow .

The same can be said of a power source. Not only does your fan have to be clean but also its interior (the first time you disassemble it you will be surprised to see the amount of dust accumulated) but it is also essential in terms of temperature, because the voltage delivery is directly related.

Finally, highlight the need to correctly place the wiring , another source of overheating and dust collection. There are special wiring and towers that make things easier but at least we must use plastic clamps to collect the wiring and leave the maximum free space inside the chassis to improve air circulation.

As we can see, preventing overheating of a PC is simple if we take it as a regular performance task. The advanced cooling components cost a lot of money, but spending a bit of our time just cleaning is free and very advantageous to avoid problems and increase the life of the components.
