Why does the laptop heat up quickly? What to do to prevent the laptop from heating up. Reasons why your computer gets too hot

The laptop is actually a full-fledged desktop computer, which was packed in compact body the size of a keyboard. Therefore, it is not surprising that sometimes laptop users encounter .

In this article we will look at a number of reasons that can lead to excessive heating of a laptop and tell you why this happens and what can be done about it.

Reason #1: The laptop is placed on a soft surface.

Placing a laptop on a soft surface, such as a sofa or pillow, inevitably leads to strong heating of its components. The problem is that placing the laptop this way leads to the fact that its ventilation holes are closed and the cooling system cannot suck in cool air or remove already heated air.

This is especially true if the laptop is initially poorly cooled, for example, it is clogged with dust. Or if the laptop is used under heavy load. In such situations, placing the laptop on a soft surface becomes the last straw, and it begins to reboot from overheating.

Solving this problem is very simple. If you want to use your laptop while sitting on the couch or in bed, then find some hard surface that you can use as a stand or table for your laptop. If you don’t have anything suitable at hand, then you can buy such a table. They can be found on the Internet by searching for “laptop table.”

To check what is causing CPU load" and sort the running processes by CPU load. If the list contains processes unknown to you that will constantly load the processor, then this is a reason to install an antivirus and check your computer. If you already have an antivirus, then try replacing it with another one.

Reason #3: The laptop cooling system is clogged with dust or faulty.

If you position your laptop correctly and you have checked it for viruses, but it still gets too hot, then the problem may be that the laptop's cooling system is clogged with dust. This usually affects laptops that are 1 year or older. In order to properly remove dust from the cooling system, the laptop must be completely disassembled. This procedure is not easy, so it is better not to engage in amateur activities and contact service center. Otherwise, laptop repair can be much more expensive.

Also, excessive heating of the laptop may be a symptom of a breakdown in the cooling system. Most typical problems are dried out thermal paste, a broken cooler or a faulty heat pipe. Such a problem can only be detected and corrected if complete disassembly laptop in a service center.

Reason #4: The laptop's cooling system simply can't handle it.

If you constantly use your laptop under high load, for example, play it in computer games for many hours in a row, then strong heating can occur even if the cooling system is fully operational. This is because some laptops are simply not designed to handle such intense workloads.

This problem can only be solved by improving the cooling of the laptop using a special stand with fans. These stands connect to the laptop connector and use fans to force cool air into the laptop's vents. This solution is quite effective and can immediately significantly reduce the temperature of laptop components. But, you will have to put up with increased noise levels.

If the laptop has lost performance, becomes noisy, and feels hot to touch, the machine most likely needs to be treated urgently. This article describes why a laptop can become very hot, what to do if this happens, and how to prevent overheating.

Should a laptop get hot? Is there a threat to the device?

How harmful is overheating for a laptop?

An increase in temperature to levels that are not normal for the comfortable operation of components can cause their failure. At best, performance is lost, at worst, components may simply burn out.

Ways to check the temperature of the processor and video card

To check whether the video adapter is overheating, you can go into the BIOS. This menu is for changing the necessary parameters without the help of third-party software.

Directly in the BIOS you need to find the section that is in different versions may be referred to as "H/W Monitor", "Health", "CPU Temperature" or "CPU Information".

Advice: If the user is not confident in his abilities, it is better not to enter the BIOS on his own, but to turn to a professional.

This is a fairly simple method, but it has a significant disadvantage. While the user is in the BIOS, the system is idle, and therefore the temperature may be lower than during normal use of the laptop. This will have to be taken into account when checking. To use the laptop, you need to return to working with Windows as usual, but then you won’t be able to check the performance.
How can you check whether your laptop is overheating during operation? There is special software for this. It is presented in the table below.

What temperature is normal for a laptop?

It is normal for a CPU to warm up to a maximum of 60 degrees: 30-40 when idle and 45-55 when loaded. As for video cards, it is worth taking into account individual characteristics specific model: TDP for cards may vary. Manufacturers indicate this indicator in the characteristics on the box or in the instructions.

Much also depends on the power of the video card. For some modern devices, a temperature of 60-75 degrees is quite comfortable, while for video cards from the past, similar indicators are an alarm.

Why does my laptop overheat?

“Popular” reasons for excessive heating are the use of programs that are particularly greedy for system resources or viruses picked up by the user while surfing the Internet, downloading games, movies, and software.

The user may not load the system, but the virus is quite capable of “eating” resources and causing harm to both individual components and the hardware as a whole. There are other, no less common, reasons.

Why does the laptop get very hot: the main reasons for overheating

How to protect your laptop from overheating? Methods for cooling a laptop

To prevent the problem of laptop overheating from even arising, you can take proactive measures.

• Timely dust removal

Depending on how often you use your laptop, you should clean it from dust every 6-12 months. If the user is sure that disassembling and, most importantly, assembling the laptop will not be difficult, then you can do without the services of a specialist. True, such intervention will void the warranty, so if you still have doubts, it is better to contact a service center. In not particularly critical cases, you can clean the device yourself without disassembling it: blow out the ventilation grilles or vacuum them.

• Service replacement of thermal paste

• Do not block the ventilation openings on the bottom and side of the laptop

In pursuit of your own comfort and the desire to distinguish your own laptop from others, you can also create conditions that are uncomfortable for cooling components. Covering ventilation holes with stickers, working on a soft surface (placing a laptop on your lap, blanket, etc.) is not The best decision: only a flat surface, only room for fans.

• Cooling pad/mat

For those who spend a lot of time on a laptop and use resource-intensive utilities, rugs or tables with built-in fans will be a useful purchase. They are powered by USB and can cool the laptop additionally.

When the laptop is running, the internal components of the system generate heat. The microprocessor and video card heat up especially strongly during operation, since these elements are the most energy-consuming. The built-in cooling system is capable of maintaining the permissible temperature of the main elements, preventing them from overheating. But if you have problems such as braking, freezing and spontaneous shutdown, then most likely the processor on your laptop is getting very hot.

Laptops vs. desktop computers Most often they fail due to overheating. This is due to the fact that the small dimensions of a laptop are not always able to accommodate a good cooling system. Therefore, make sure that your device is not exposed to elevated temperatures, so it will last much longer.

Why does the processor on a laptop get hot?

There are 4 main reasons that provoke overheating not only of the microprocessor, but also of other components. Each of them is presented below.

Cooling system contaminated with dust

Description of the problem: If you use an air cooling system, then over time the ventilation holes and the cooler become covered with a layer of dust, which impedes the flow of air. For this reason, the system, including the processor, most often overheats.

Signs: strong, incessant fan noise, raising the processor temperature to 70°C or more when working with undemanding programs, as well as spontaneous shutdown of the laptop.

Solution: Carrying out the laptop cleaning procedure. Read how to do it yourself.

Damage to the structure of the thermal pad or wear of the thermal paste

Description of the problem: depending on the laptop model, a thermal pad or a layer of thermal paste is used between the cooling surface of the cooler and the processor cover, which lose their physical properties over time. This usually happens after 1-2 years of using the device.

Signs: the same as in the previous version.

Solution: partial disassembly of the laptop and cooling system with subsequent replacement of the thermal pad or thermal paste. If you are not sure that you can cope with this task, it is better to immediately contact the service center.

Virus infection

Description of the problem: Malware in some cases can heavily load the operating system, thereby causing the processor to heat up.

Signs: CPU load is 60-70%, even when no program is running (except background ones).

Solution: cleaning the system from viruses and malware. Read the detailed guide.

Using too demanding programs and games

Description of the problem: Running excessively system-intensive programs or video games on a laptop can cause the processor to become very hot.

Signs: spontaneous shutdown or reboot of the laptop while playing or working with a program, severe braking and system freezing.

Solution: Use a laptop cooling pad, and to prevent the laptop from suddenly shutting down while playing a video game due to overheating, reduce the maximum processor power from 100 to 70%. To do the latter, do the following:

1. press the "Start" button to call context menu and select "Power Management";
   
2. in the window that opens, click on the “Configure power supply scheme” button;
   
3. go to the "Edit" section Extra options nutrition";
   
4. in the new window, scroll down the list and expand the “Processor power management” category;
5. then expand "Maximum CPU State";
6. change the value from 100 to 70%.

If you don’t know and if this is not the first time you have noticed that its case gets very hot, the cooler inside the laptop makes a very loud noise, and your laptop, previously fast and reliable in operation, now often slows down and crashes, and perhaps it began to suddenly turn off during your work and you just can’t understand the reason for this behavior of your computer, then it is quite possible that the root of the above troubles is overheating of the laptop itself, which, ultimately, can lead to the final failure of your device. In this material, we will look at the reasons for your laptop overheating, give tips on how to avoid it, and also look at methods for cleaning the cooling system, which will make your PC reliable, fast, and durable in operation.

What is “laptop overheating” and what to do if it gets too hot?

During operation of the laptop, I consume its electrical components. electricity, some of which turns into heat, helping to raise the temperature inside the PC case. Therefore, the greater the load on the central processor and video card, on the northern and south bridges(chips) of a laptop - the more heat will be generated inside your computer, the more noise the cooler will make, the more your computer will overheat and crash.

Note that older laptops heat up significantly more than modern models, which is due to the use of less efficient systems cooling. Modern innovations and improvements in the quality of overheating control make it possible to improve the cooling process of modern laptops, making the operation of such PCs more efficient and reliable. Plus to this, modern processors are manufactured using advanced energy-saving technologies that help significantly save energy consumption and reduce processor heat dissipation.

Why is my laptop overheating?

There are several reasons for a laptop to overheat; we will look at the most common ones. So:

Significant load on system components Your laptop causing overheating can be caused by many simultaneously running utilities, browser tabs, as well as powerful modern computer games that use many of your computer's resources. Moreover, the use of such programs on office laptops, not intended for powerful and resource-intensive games, causes significant overheating such computers.

Cooling system contamination

A standard laptop cooling system usually consists of a radiator, a cooler (fan) and a heat pipe, as well as vents on the case.

Contamination of these holes, the accumulation of dust and all sorts of fluffy parts of matter there can make it impossible for hot air to fully escape from the laptop case, leading to its concentration inside, which can cause overheating and malfunctions of the computer.

If the user practices careless operation of his laptop, keeps it in dusty rooms and on various fleecy surfaces, and does not clean the cooling system, then the laptop will begin to overheat, and then may even fail, and this can happen within a year or two after its use. purchases.

Cooling system failure

The laptop cooling system may break down, the fans (coolers) will fail, the thermal paste, the function of which is to remove heat from the hottest elements of the system, will dry out, and the heat pipe may also break. Typically, system elements do not fail overnight; there is a gradual decrease in their performance (the cooler begins to hum and vibrate, the system begins to periodically turn off, etc.). Therefore, if your laptop cooler is loud or the system suddenly turns off - It is worth checking the functionality of the cooling system, and if necessary - replace faulty elements.

How to deal with laptop overheating?

To ensure long-term and reliable operation of your computer, it is worth focusing on the basic techniques for combating its overheating. Namely:

Reduce CPU load

Try not to run many applications and web pages at the same time, this significantly increases the load on your laptop, causing it to " slowdowns", overheating and so on. Various virus programs that work hidden from the user and significantly load the processor also contribute to overheating of the computer. Conduct an anti-virus scan of your computer, do not run many resource-intensive applications at the same time, do not try to overclock your “office” laptop for resource-intensive gaming programs - and your laptop will be able to avoid overheating and will work reliably and efficiently.

Cleaning the laptop cooling system from clogging

It is necessary to adhere to the correct technique for using a laptop, do not work with it on all sorts of fluffy and soft surfaces (sofa, bed), since particles of wool and dust get into the ventilation holes of the laptop and clog them, preventing fresh air from entering inside your laptop. Therefore, it is better to keep your PC on flat surfaces (for example, on a table) or on your lap in such a position that the ventilation holes are always open and fresh air can easily flow inside.

It is also necessary to regularly (at least once a month) clean the ventilation holes in the housing from clogging. To do this, you need to remove the bottom cover of the laptop, unscrew the fastening screws, remove the cooler, and then clean the ventilation holes with a brush, removing balls of dust and hair from them. Then you should put the cooler in place, tighten its screws, and then close the bottom cover. If you feel unprepared for such a procedure, then contact a service center or IT specialist with a similar request, and they will help you clean your laptop from clogging for a nominal fee.

Changing dried thermal paste

Typically thermal paste that allows heat to be effectively removed from central processor, applied to its surface and hidden from the user’s eyes by a cooler attached to the surface of the processor. Typically, the lifespan of thermal paste lasts several years and depends both on its quality and on the thickness and area of ​​application of the layer. It is recommended to change the thermal paste every 1-3 years to prevent it from drying out and the processor from overheating.

Buy a cooling pad

To reduce overheating of your laptop, you can purchase a special cooling pad for your laptop. Universal stand models can be easily adjusted to fit the size of your laptop, and the heat-dissipating surface of the stand and the coolers built into it will help effectively cool the bottom surface of your computer.

Limiting processor power

You can also use the operating system to limit the power of the central processor, setting its maximum operation to 60-80%, which will help reduce its overheating. To do this, go to the control panel, click on “system and security”, select “power”, and then “set up power plan”. Click “change additional parameters”, then select “processor power management”, then “maximum state” and set the indicator, for example, to 60% from the network and battery.

Conclusion

The quality and speed of a laptop directly depends on the functionality and reliability of its cooling system. It is necessary to regularly clean it from clogging, take care to maintain its high performance, change failed elements of the cooling system - and then the likelihood that your laptop will serve you for many years will increase significantly. If necessary, you can contact your local service center, where specialists will clean your system of dust, change thermal paste and test other computer components.

Now you know, what to do if your laptop gets too hot and remember that regular and timely prevention of computer breakdowns is a necessary guarantee of its high-quality, reliable and long work and good luck to you.

If programs begin to slow down and freeze, the cooler begins 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 properly. Cold air ceases to flow in optimal quantities, which causes overheating of key parts. You can get rid of this problem by cleaning.

Among the main components of a laptop that constantly overheat are the video card, CPU and chipset. Maximum heating becomes noticeable when serious and massive data is processed. This usually happens during operation graphic applications, launching new games, video editing high resolution. In just a couple of minutes, the temperature of the gadget can increase by tens of degrees. After heating, the heat itself must pass into the radiator and cooler system, from where it is “thrown out” outside the device.

When a new device is purchased and there is no dust in the heatsink, the device will not heat up very much, since the system does an excellent job of dissipating heat from key components. However, after a certain period, dust begins to accumulate on 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 when the temperature is too high, since there is a high chance of permanent breakdown of the laptop.

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

Why does my laptop start to heat up? Main reasons and problems

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

• shortcomings 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 cooler, radiator. Often, dust penetrates the radiator grille and covers the main components, which is why cooled air can no longer pass through. Sometimes, after a layer has formed, the fan stops rotating quickly;
• violation of the insulating layer. As a result of prolonged operation of the laptop, the thermoplastic dries out, as a result, thermal conductivity deteriorates, which provokes overheating;
• failure to comply with basic operating requirements. 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?

The following signs will help you understand that your laptop is starting to get very hot:

• actively running fan while gaming or watching media. The laptop may turn off spontaneously, especially when resource-intensive programs are launched, such as games and a 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 errors, driver failures and OS problems;
• Games periodically lag. The user does not feel “smooth” while playing new games; after 30 minutes to an hour, the laptop turns off spontaneously. The thing is that the processor and graphics card They cannot cope with too high a temperature and cannot fully process the image.

What to do if your laptop gets very hot and makes noise?

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

Removing unnecessary programs from startup

So, first you need to get rid of unnecessary and unnecessary programs, which are in startup (launched in automatic mode after the laptop turns on) to reduce system load.

You can manage automatically downloaded programs using MSConfig utilities– it allows you to see which utilities are launched along with 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:

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 only one fan, then it will be located in the center of the stand, but if there are at least two of them, then one of them will be just as close as possible to the place where the heat is generated. A cooling pad will have 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 place it on books so that the ventilation holes are open. This also helps, but not very much.

Removing processes that load the CPU

Additionally, you should consider reducing the processor power by several tens of percent. This will also affect the heating graphic component, since their work is interconnected with each other.

Cleaning the laptop cooling system from clogging

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

1. Turn off the power to the laptop and remove the battery.

   

2. Remove the DVD drive - to do this, simply unscrew one (two) screws on the back of the case.

   

3. Disassemble the laptop, disconnect the main HDD and RAM in the same way (they are secured using special brackets, which must first be bent).

   

4. Separate the bar at the location of the speakers above the keyboard. If you have difficulty removing the bar, then you first need to unscrew the screws.

   

5. Remove the cable - to do this, pull the fastening tab upwards, after which the cable will be removed.

   

6. Disassemble the keyboard. It is secured using the same plastic latches - their number varies from 4 to 8. It is recommended to first remove the upper corner latch - just press on it with a flat-head screwdriver and pry off the corner. You can also unclip other fasteners using the same method.

   

7. will become visible motherboard– in this case it is also necessary to unscrew the screws to disconnect it from the body.

   

8. On the other side motherboard The cooling system and fan are located - they should also be removed by unscrewing the main fasteners.

   

9. Dust is removed from the slats using a special brush or compressed air. To clean the fan you will need to get graphite lubricant.

You need to determine how well the cooler rotates. If the laptop was noisy during operation, then this component should be disassembled, cleaned, and lubricated.

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

How to prevent the system from overheating?

To no longer encounter the problem of system overheating, just follow certain recommendations:

• It is better not to run on a regular basis those applications that require a lot of resources - these are graphics 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, since in this case the case will heat up too much;
• As a preventive measure, it is better not to place the laptop on soft surfaces when it is actively working;
• if the laptop has been actively used for more than a year, you should disassemble the device, replace the thermoplastic and clean 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 permissible temperature of the laptop. Approximate optimal indicators will be given, which vary depending on the laptop model and area of ​​​​use.

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

Thus, the most common reason Overheating of a laptop is caused by clogging of the cooling system and cooler. Due to the dust layer, the main components stop functioning 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 new layer thermoplastics. As a result, the gadget will stop overheating and will again delight the owner with its excellent performance.
