The processor on the laptop overheats what to do. Laptop gets very hot

⁰

While the laptop is operating, its electronic components consume electricity, a certain percentage of which is converted into heat. With an increase in the power of the processor and video card, the interior of the laptop heats up more.

The problem is quite common, so it is important for every laptop owner to know what to do if the laptop gets very hot and turns off by itself.

Cooling system device

The heat sink system tightly adjoins the processor and often the video chip. It consists of copper pipes that conduct heat to the grill, which is blown by air from the fan and cools because of this, thereby lowering the temperature of the processor and other nearby components.

The distance between the plates of the cooling grille is extremely small, in connection with this, the dust quickly fills the space between the fins, forming a felt that interferes with the passage of air.

The tightness of the copper cooling plate to the processor or video chip is provided by thermal paste and thermal pads. A thermal pad is an elastic band that adheres tightly to two surfaces. The absence of thermal paste or thermal pad will create an air gap that will reduce the efficiency of the cooling system.

The processor itself has a flat surface with a copper cooling plate attached to it. The video chip has the same flat surface.

To ensure that there is no air between the copper plate and the processor, a layer of thermal paste is applied. The thermal paste evens out uneven surfaces of the processor and cooling system, creating the necessary fit and providing excellent heat transfer between them. The thermal pad performs the same function.

Signs of overheating

There are many signs of a significant increase in laptop temperature, depending on which part is prone to overheating, so consider the most common:

laptop turns off unexpectedly. The system of protection against excessive high temperature is responsible for turning it off, therefore, after turning off the computer, it is recommended to turn it on and enter the BIOS, where it is necessary to monitor the temperature parameters of the base nodes of the portable computer, if possible;
intermittent freezes and reboots. Most likely, the problem lies in the excessive heating of the video card. An additional factor may be the distortion of the picture in gaming applications and the appearance of so-called "artifacts";
laptop makes a lot of noise. If the fan is noisy, then you should clean the cooling system or completely replace it;
hot body. With a significant overheating of the laptop case, you should seriously think about fixing this problem. Often a hot case is combined with loud fan operation. Cleaning the fan and cooling system completely, if the laptop case is very hot, is simply necessary - otherwise the device may cause burns;
if the files began to be slowly read from the hard drive, or it is impossible to read data at all, it is necessary to focus on the temperature of the hard drive.

Causes and remedies

There are several main reasons for excessive heating of the laptop. For each of them, there is an effective method for fixing the problem when the laptop heats up.

Dust

The most harmless and common cause of laptop overheating is commonplace dust. Over time, it clogs the ventilation grate (in extreme cases, the thickness of the dust layer can reach a centimeter), and makes it much more difficult for cold air to get through the grate.

Limiting the supply of cold air inside the laptop leads to significant heating of the processor, video card and other components.

Signs of this cause are the random shutdown of the laptop after a certain period of time (usually from 10 to 30 minutes), performance degradation, fan noise. These signs are especially pronounced in the summer heat.

To eliminate this problem, the cooling system should be cleaned of dust. An ordinary household vacuum cleaner can become an excellent assistant in this matter.

Dry thermal paste

Another cause of laptop overheating is thermal paste drying out. This cause is more rare than the previous one, however, thermal paste drying out and thermal pad failure are quite common.

In general, liquids transfer heat well, which is why water cooling is more effective than air cooling. When the paste dries out over time, the percentage of liquid in it decreases, which means that the cooling efficiency decreases, although not significantly.

Otherwise, the situation is with the thermal pad. When exposed to high temperatures, the thermal pad wears over time, compact micro-tears occur in it, which cause its function of transferring heat from the processor to the cooling system is reduced.

Signs are similar to signs when the ventilation hole is dusted. To eliminate these difficulties, it is recommended to replace the thermal paste and thermal pad.

Failure

If after cleaning and replacing the thermal paste, when the processor load is less than 25-40% in office applications, the processor temperature is more than 80C, then most likely there is a failure of the cooling system or board elements. In this case, it is most advisable to take the laptop to a service center.

Cooling systems

Over time, the cooling system ceases to provide an acceptable level of cooling. The fans begin to spin less, the rotation axes are shifted. It often happens that the installed cooling system may not provide cooling under significant loads from the user.

To solve problems, it is recommended to change the components of the cooling system, or completely replace it. The choice of optimal components and their installation is impossible without qualifications and experience, so you need to contact the skilled specialists of the service organization.

Another way out of the current situation associated with overheating can be to purchase a stand with fans. By placing a laptop on it, you can achieve a more significant airflow through the case and, as a result, lower the internal temperature of the laptop.

Board elements

The heat that is released when the CPU or motherboard chip heats up is transferred to the nearest nodes placed on it. Under prolonged and significant exposure to heat, there is a possibility of microcracks forming at the soldering points of these components, which leads to significant heat generation and faster wear.

Why is overheating dangerous?

With an increase in the amount of dust, the efficiency of the cooling system noticeably decreases, the laptop begins to heat up actively, and over time it may freeze or even overload.

But the worst thing is that overheating of the laptop can cause the following components to break:

Replacing a video chip or other components costs many times more than prophylactic cleaning of a computer from dust. It should be a rule that if the laptop began to spontaneously switch, it needs to be cleaned of dust.

How to check if laptop is overheating

To determine what temperature is the limit for a computer, you can use the special HWMonitor program, which allows you to view all current, as well as maximum and minimum temperature values for a specific period of time. Of greatest interest will be exclusively the maximum values.

Each device has its own temperature limit, certain information can be found on the Internet, something is easy to find out experimentally, but usually a combination of several symptoms with clearly overestimated values in HWMonitor indicates that the laptop needs cleaning and prevention.

However, be aware that the temperature limit may vary for each model.

Prevention measures

Typically, a laptop gets very hot due to dust and lint clogging the radiator of the cooling system, so a few simple rules will help you avoid complications associated with overheating:

you can’t put the laptop on soft surfaces while working, due to the fact that they interfere with acceptable cooling and the villi from the soft surface clog the fan pretty soon;
you can not work in a room with a lot of dust;
the lion's share of household dust is at a height of up to 20 cm from the surface, so it is not recommended to work with a laptop on the floor;
it is necessary to periodically clean the laptop from dust (at least once a year);
before purchasing a laptop, it is important to determine what it will be used for, and choose the most suitable model for this particular class of tasks. It's important to know that true gaming laptops don't exist.

Just a few trivial rules can protect your laptop from failure or an unscheduled trip to a service center.

Overheating of a portable computer can cause a lot of headaches, ranging from the well-known “blue screens” to the loss of important data and even a direct breakdown of the motherboard or processor, and the user does not always understand why the laptop began to overheat.

Miniaturization is an inevitable process in the evolution of comfort. A compact device is always easier to transport. If you need to have constant access to the functionality of the device, its size is of great importance. Despite the progressive capabilities of laptops, the device also has a number of disadvantages. The main problem is voiced in the question: “Why is the laptop heating up?” If you are interested in information about the probable causes that increase the temperature of the device, and you want to know how you can eliminate such “inflammation of the iron”, then the material presented in this article will be as useful as you can correctly put it into practice.

Lack of free space and its consequences

Notice how much smaller a portable computer is than its desktop counterpart. However, the power and performance of the "baby" can be several times higher than that of its "giant opponent". However, the time factor always dots the i... One way or another, a device used for a long time (especially when all the hardware resources of a computer are involved) will inevitably start to warm up. The extremely dense neighborhood of components in the inside of the case is an incredibly favorable environment for increased heat transfer. Question: “Why is the laptop getting very hot?” becomes especially relevant if, in addition, the user is placed on the couch. In this case, the soft upholstery of the headset becomes a kind of additional barrier for the much-needed air cooling system. Why is that? The main limiter is usually the casing of the device, the ventilation holes of which sometimes cannot provide sufficient air circulation. How to avoid the negative effects of heat and what to do to ensure that the laptop works with a "cold calculation" - read the material below.

Why a laptop gets very hot: case flaws

The iron "organism" of your electronic device, as a rule, frames the plastic case. In the event that a laptop model is involved in budget-class technology, the risk of overheating of internal components increases with each slightly incorrect operational action. For example, using a laptop on your lap or working the device on a soft surface is obviously wrong. When you work on a laptop in a dusty room or in high humidity, be aware that negative consequences cannot be avoided. Incidentally, the cold environment also has a devastating effect on the laptop as a whole. It is reasonable to assume that the question: “Why is the laptop heating up?” it might not have been if the user was aware of all the operational nuances.

What will the seller not say, or What is the manufacturer hiding?

First of all, it should be remembered that a laptop is a portable device that can function autonomously, without being tied to a power supply. However, if you are using a laptop as a desktop PC, then you should not forget that “long straining” of the device can be fatal for the device if the user ignores the tactilely felt effect - a hot case. Even if you were assured that the laptop was made taking into account all operating conditions, do not believe it - you are being misled. However, some modifications of portable computers are indeed adapted for use in extreme conditions. Nevertheless, even happy owners of reliable devices may have a question: “Why does the laptop heat up and turn off?” Developers and manufacturers of portable computer equipment can assure the authoritative competence of their "brainchild", but the temperature fact remains inevitable evidence: everything is subject to the destructive influence of high temperature. Therefore, it makes sense to constantly monitor the "degrees" of the components of a long-running system.

Top "hot" problems and how to fix them

So, why is the laptop heating up and shutting down? Let's look at the main reasons for this phenomenon, and at the same time we will understand some of the technical nuances and design features of the laptop.

Problem #1: Dust Exposure

As already mentioned, computer components are “constrained” by the framework of the framing structure, so to speak, by a protective shell. This part of the device can be made of different materials. Various polymers, metal frames made of steel and even titanium in use allow you to give the laptop a different level of reliability. Many of the materials have an incredibly efficient ability to absorb heat. However, open areas and air intakes are most exposed to the constant effects of the external environment: dust, moisture, etc. Often the user has a question: “Why does the laptop get so hot?” Most likely, a critical accumulation of microscopic debris has occurred inside the laptop. Dust particles are compressed around the cooling cooler and block the inlet / outlet of air with their quantitative mass. As a result, the fan lubrication becomes clogged, and friction creates an unpleasant effect of third-party noise.

Remedy #1: Surface Cleaning

As a rule, such troubles are resolved by elementary preventive actions:

The outer openings of the air channels are freed from dust deposits using an ordinary construction brush for painting.
You can use a household vacuum cleaner.
In some cases, in order to correct the situation leading to the question “why the HP laptop is heating up”, it is necessary to dismantle the protective cover of the case, which covers the direct location of the cooling fan.

Attention: the implementation of the last paragraph deprives the user of the manufacturer's warranties. Since unauthorized access is a violation of operational rules.

Remedy #2: "Through the lid to the target"

If the warranty period has expired, then the user has every reason to independently restore the cooling system to working capacity. Except for contacting a specialized service center.

Turn the laptop over and use a screwdriver to unscrew the screws of the cover, which is usually located in the upper case, on the left (rear view).
After dismantling the protective element, use the same brush (see above) to clean the contaminated area. It is worth noting that in a situation where the question is as follows: “Why does the laptop make noise and heat up?”, Superficial “cleaning” is not enough - you need to lubricate the fan. In some cases, it is advisable to replace the cooling cooler.
After completing the "sanitary" work, install the cover in its original position, initially making sure that there are no extra items in the niche that you have cleaned of dust.

As a result of the fact that the cooling system ceases to fully function, it often happens that in the process of working in the Windows operating environment, the computer “freezes” or simply turns off. In the first case, perhaps the system does not have enough RAM, in the other case, there is a violation of the temperature regime. An emergency shutdown is triggered by the BIOS service.

Remedy #1: Polluted RAM

To clean the installed RAM lines from dust, you also need to open the corresponding protection plate. It is usually located in the middle of the casing and is fixed with two screws. Open, clean and replace the cover. In some cases, you will need to "build up" the potential of RAM - adding memory.

First of all - diagnostics

Often, access to the central processor is somewhat difficult and is associated with the immediate moment of dismantling the body parts and even some of the add-on modules of the system. Therefore, it is advisable to carry out equipment diagnostics in order to make sure that there are grounds for a labor-intensive process. Indeed, sometimes a visual analysis can indicate the real reason why the laptop began to warm up. It is not difficult to carry out such a check, for this it is enough to enter the BIOS and see the current temperature readings of the processor in the corresponding menu. There are also standard Windows tools that can be used to verify that the CPU is operating normally. In other cases, dismantling cannot be avoided.

Elimination method number 2: a substance on which a lot depends ...

The operation of the processor is accompanied by high heat dissipation. If the cooling system is not functioning properly, then the thermal paste dries out. The mentioned substance serves as a kind of layer between the CPU die and the heatsink, which absorbs the heat coming from the processor. As you understand, to replace the thermal paste, it is necessary to remove the cooling part and clean the contact surfaces from traces of the dried substance. It should be noted that the component involved in heat transfer is applied evenly, in a thin layer, and in no case goes beyond the boundaries of the processed planes.

Problem #2: Hot video effects and resource intensive software

Software, and in some cases, multimedia material, is often the cause of the question: “Why is my laptop heating up?” First of all, pay close attention to how the graphics card works. When the graphics are displayed on the screen, the processor starts to “strain”, and if the user has downloaded a modern toy to his portable device, the system will use all its resources, and then the hardware potential is laid out to 100. High performance requires more energy consumption, hence the increase in heat dissipation system components. Of course, you know that a powerful graphics card needs effective cooling, and that the GPU, like the CPU, has a fan cooler. Of course, the fan blades and the discreet heatsink can become clogged with dust. In this case, there is a risk of overheating of the video card parts, and the question: “why does the laptop heat up when you play” requires immediate resolution.

Remedy number 1: software "troubles"

A lot of simultaneously running software can also cause your computer to overheat. It would be better if you disable some applications. Firstly, you will significantly increase the performance of the system, and secondly, you will not overload the hardware of your laptop.

Workaround #2: Discrete Cleanup

As a rule, the graphics module is located in close proximity to the air channel grilles. Therefore, it is not difficult to calculate the exact location of a discrete video card. By unscrewing the appropriate screws, you can dismantle the protective cover and clean the part from dust deposits.

Finally

So, we examined why the laptop is heating up. However, the issue cannot be considered closed without discussing one more important point. The fact is that another cause of the problem of interest to us may be the laptop battery. To verify the reliability of suspicions, it is enough to use a special utility or contact a specialized workshop in order to diagnose and receive recommendations. Do not forget about a simple operational rule: a laptop computer during operation should be located on a flat table surface so that nothing prevents air from entering the interior of the laptop. As you have probably seen, there is nothing difficult in understanding and resolving the problem we are discussing. Timely preventive actions will help you prevent the negative consequences of such a property of the unit, and let the systematic temperature monitoring of the laptop become a mandatory rule for you. Productivity to you and successful service!

If programs start to slow down and freeze, the cooler starts to make noise, and the laptop itself constantly turns off, then most likely it has overheated. The most common cause of this problem is the presence of dust that covers the cooling and ventilation system, due to which it cannot function normally. Cold air ceases to flow in the optimal amount, which provokes overheating of key parts. You can get rid of this problem by cleaning.

Among the main components of a laptop that are constantly overheating are the video card, CPU and chipset. The maximum heating becomes noticeable when serious and massive data are processed. Usually this happens in the process of functioning of graphic applications, launching new games, editing high-definition video. In just a couple of minutes, the temperature regime of the gadget can rise by tens of degrees. After heating, the heat itself must pass into the radiator and cooler system, from where it is "ejected" outside the device.

When you buy a new device and there is no dust in the heatsink, the device will not get very hot, because the system does an excellent job of dissipating heat from key components. However, after a certain period, dust begins to accumulate on the cooler radiators and other elements, which makes it difficult to release heat outside the laptop. Often the heating of the gadget becomes critical and an urgent power outage occurs. It happens at excessive temperatures, since there is a high chance of a final breakdown of the laptop.

Important! To prevent this, it is recommended to clean the devices on a regular basis, or at least purchase a passive or active cooling pad, which helps to reduce the temperature by a few degrees.

Why is my laptop overheating? Main causes and problems

To solve the problem described above, its root causes should be identified. This is about:

flaws of manufacturers involved in the design of the cooling system. This usually applies to cheap models, employees of new brands do not conduct test work to reduce the cost of the device;
contamination of components such as a cooler, radiator. Dust often enters the radiator grille and covers the main components, making it impossible for the cooled air to pass through. Sometimes, after the layer has formed, the fan stops rotating rapidly;
breaking of the insulation layer. As a result of prolonged operation of the laptop, the thermoplastic dries out, as a result, thermal conductivity deteriorates, which provokes overheating;
non-compliance with the main requirements of operation. In some situations, users themselves are to blame for overheating of the gadget. The design of the laptop case implies the presence of technological holes into which cold air enters. The user may not notice them and constantly block them.

What are the signs that your laptop is overheating?

To understand that the laptop is starting to get very hot, the following signs will help:

an actively running fan while playing games or watching media. The laptop can spontaneously turn off, especially when resource-intensive programs are launched - the same games and video player. After cooling down, the laptop turns on again;
occur frequently. Of course, this is not always directly related to overheating. Freezes can occur due to software bugs, driver failures, and OS issues;
games intermittently freeze. The user does not feel "smoothness" while playing new games, after 30 minutes or an hour the laptop turns off spontaneously. The thing is that the processor and graphics card can not cope with too high temperatures and cannot fully process the image.

What to do if the laptop is very hot and noisy

If the user is faced with the problem of overheating of the laptop, he should take a number of actions to avoid this difficulty.

Removing unnecessary programs from startup

So, for starters, you should get rid of unnecessary and unnecessary programs that are at startup (starting automatically after the laptop turns on) to reduce the system load.

You can manage automatically loaded programs using the MSConfig utility - it allows you to see which utilities are launched with the operating system, remove them, and so on. Moreover, MSConfig is used not only for this purpose, so you should be extremely careful when using it. To run MSConfig you should:

Buying a cooling pad

Additionally, it is recommended to purchase a cooling pad. Inside, it includes several fans that serve to cool the case. It is better to buy a model with several fans at once, since the main components such as the processor and video card are located on the edge of the device, next to the ventilation holes - if there is one fan, then it will be located in the center of the stand, if there are at least two, then one of them will just as close as possible to the place where the heat is released. A cooling pad will give a significant effect, but it is still worth remembering that at some point you will need to clean the laptop from dust even if you use the stand. Many people lift the laptop and put it on books so that the ventilation holes are open. This also helps, but not much.

Removing processes that load the CPU

Additionally, you should do a decrease in processor power by several tens of percent. This will also affect the heating of the graphical component, since their work is interconnected with each other.

We clean the laptop cooling system from clogging

Cleaning the laptop cooling system from is the most effective way to deal with the problem of device heating. To do this, you will need to perform a number of actions, namely:

Power off the laptop and remove the battery.
To remove the DVD drive - for this, it is enough to unscrew one (two) screws on the back of the case.
Disassemble the laptop, disconnect the main HDD, RAM in the same way (they are fixed using special brackets, which must first be bent).
Separate the bar at the location of the speakers above the keyboard. If you have difficulty removing the bar, then you must first unscrew the screws.
Remove the train - for this, the fastening tongue stretches up, after which the train will be removed.
Disassemble the keyboard. It is fixed using the same plastic latches - their number varies from 4 to 8. It is recommended that you first remove the upper corner latch - just press it with a flat screwdriver and pry off the corner. In the same way, you can snap off other fasteners.
The system board will become visible - in this case, it is also necessary to unscrew the screws to detach it from the case.
The cooling system and fan are located on the back of the motherboard - they should also be removed by unscrewing the main fasteners.
Dust from the slats is removed using a special brush or compressed air. To clean the fan, you will need to get graphite grease.

It is necessary to determine how well the cooler rotates. If during the operation of the laptop it was noisy, then this component must also be disassembled, cleaned, lubricated.

Important! Before assembling the laptop, it is highly recommended to apply a layer on the chips. It is better not to use the KPT-8 model that is in demand today, which differs by far from the most effective properties. Its thermal conductivity is not effective, there is a tendency to dry out after a certain period of time.

How to prevent system overheating?

To no longer face the problem of overheating of the system, it is enough to follow certain recommendations:

it is better not to run on a regular basis those applications that require a lot of resources - these are graphic utilities and modern games. Because of them, the CPU and video card operate at maximum power and heat up excessively;
the computer should not be exposed to direct sunlight, because in this case the case heats up too much;
as a preventive measure, it is better not to put the laptop on soft surfaces when it is actively working;
if the laptop has been actively used for more than a year, you should start disassembling the device, replacing the thermoplastics and cleaning the fan along with the cooling system using a compressed air cylinder;
additionally purchase external cooling, such as special stands.

What is the normal temperature for a laptop?

Now we should move on to the issue related to the allowable temperature of the laptop. Approximate optimal indicators will be given, which vary depending on the model of the laptop and the area of \u200b\u200bits use.

normal CPU temperature is 30-50 degrees, maximum - 70 degrees;
normal GPU temperature is 40-65 degrees, maximum - 85 degrees;
the normal operation of the hard drive is 30-40 degrees, the maximum is 45 degrees.

Thus, the most common cause of laptop overheating is clogging of the cooling system and cooler. Due to the dust layer, the main components cease to function normally and do not allow the device to fully cope with its tasks. To solve the problem, you will need to disassemble the laptop and clean it, additionally apply a new layer of thermoplastics. As a result, the gadget will stop getting very hot and will once again please the owner with its excellent performance.

Video - The laptop is heating up, what should I do?

The performance of computers and laptops has increased significantly in recent years. This resulted in improved performance in resource-intensive applications and games, as well as increased heat dissipation during operation of the device.

The following laptop components are subject to the greatest heat:

CPU;
video card;
south and north bridge.

In the worst case, excessive heat can damage your mobile PC and costly repairs.

Cooling system design

Each laptop has a special compact cooling system inside, which is designed to remove excess heat and ensure the normal functioning of components.

Consider the main types of cooling systems:

passive;
active;
liquid.

Passive systems include only a variety of radiators and heat-conducting pipes. They are used most often in devices that are characterized by relatively low performance.

The active system, in addition to heatsinks and tubes, includes heatsinks, heat pipes and fans. The latter are responsible for blowing the heated passive elements and thereby improve heat transfer. This is the system used in most modern laptops.

Liquid systems are somewhat different in their structure. Instead of air, they use liquid to remove heat, passing through special tubes and cooling the heated PC components. Liquid cooling is rarely used in laptops, for example, in some experimental Toshiba models.

The standard laptop cooling system consists of the following parts:

radiators;
heat-conducting copper plates and tubes;
thermal paste;
one or more fans.

During operation, the radiators and tubes heat up, and the fans blow through them, blowing hot air through special holes in the mobile computer case. Thermal paste serves to improve contact between the chip and the heatsink, which improves heat transfer.

Signs of heating

The lifespan of a mobile computer depends on the conditions of use and the maximum temperatures it is exposed to. In some cases, overheating may even melt the body of the device. Recognizing problems with cooling can be quite simple.

Consider the main signs of excessive PC heating:

If the situation has not yet gone too far, then problems may only appear when using resource-intensive applications or while playing. Do not postpone the solution of the problem until later, as this can lead to the failure of the device.

Causes and Solutions

There can be many reasons for overheating. Most of them can be fixed by the user.

The main causes of overheating:

dust and contamination of internal parts;
dried thermal paste;
malfunction of the cooling system;
failure of motherboard components.

Dust

Over time, dust and wool accumulate inside the computer case, because of this, the laptop becomes very hot. This problem will not occur if you periodically carry out preventive cleaning using a can of compressed air, which can be purchased at any computer store.

If the computer still began to overheat, then dust removal is the first thing to do.

Steps to clean your laptop from dust:

disassembly;
removal of radiators, fans and heat pipes;
dust cleaning;
fan lubrication and replacement of thermal paste;
assembly;
checking the temperature of important elements (central processor, video card, etc.).

It is worth noting that for a user who is looking for an answer to the question for the first time: “Why does the laptop make a lot of noise and heat up?” it is not recommended to clean it yourself without the help of a specialist, since there is a high probability of damaging small parts during the assembly and disassembly stages.
