The main component of any computer is the motherboard. It is to it that all the components of the system are connected, without it the functioning of any personal computer is impossible. Therefore, in the event of a malfunction, the user is faced with a lot of problems, the most basic of which is overheating. So, and how to determine the source of trouble?
The first signs of overheating and its consequences
The most common symptoms of motherboard is warming up the following:
- Abrupt system reboot, regardless of the user's occupation;
- The computer turns itself off;
- Games freeze, crash, the system hangs tightly during the game (only rebooting the system helps).
- 15-20 minutes after turning on the computer freezes.
List of components that are most often exposed to overheating:
- Video card;
- CPU;
- Power Supply;
- Chipset on the motherboard;
- HDD.
In order to understand what overheats from this in one case or another, we will analyze each of them in more detail. But first, you should know with which programs you can determine the temperature of each of the components.
Diagnostics of the motherboard
To get data on the temperature of all elements of the system, including the motherboard, you need to use convenient programs that you can easily find on the Internet. For example, CPUID HWMonitor or AIDA64.To monitor the temperature of the processor, you can use the program CoreTemp, for video card TechPowerGPU— Z... After installing these utilities, you can easily find out everything about the state of your system, voltage, temperature and more.
In most cases, the temperature norm for the motherboard can be considered 30-50 degrees, 60 is the limit. This is often the case, and these are normal values. For each individual plan, the instructions indicate its operating temperature range. We strongly recommend that you clarify this indicatively, since the ranges can vary significantly in different models of boards.
Modern motherboards are equipped with temperature sensors, but there are some that lack them. In this case, even with the help of programs, you will not in any way determine the indicator of interest. The check can still be carried out, but only with the help of external thermometers, for example, an infrared non-contact thermometer.
The problem of overheating is most common in the warm season, when the air temperature begins to exceed 30 degrees, in hot days 35-40. Of course, this very strongly affects your system, many gamblers have problems with overheating even on absolutely working systems, only air conditioners and fans save. Because of overheating, you can easily face a series of problems, and for online gamers it is a disaster. If the motherboard does not survive severe overheating, the user can burn most of the other components, almost always the processor immediately "dies". A video card can also go after it.
Motherboard problems
For the average PC user, testing a motherboard is not easy. But still, it is worth considering some signs that the computer is unstable precisely because of the motherboard.
The first thing to think about is that the board is dying, and this, indeed, happens quite often. This process is irreversible, and it is better to discard the idea of \u200b\u200brepair right away, because even after it, its service life will remain unknown. It can work for a year or a week, but you will pay money for re-soldering or replacing components. If your PC is not quite old yet, it is best to buy a new board, preferably exactly the same one if it suits you. If your computer is more than 5 years old, you should consider a major upgrade. But this option is unprofitable in the financial sense, since at the current dollar exchange rate for the price of components on a PC, you can buy a car.
Another reason is microcracks in the board soldering. In this case, it is better to buy a new board right away and forget about the problem.
Does the computer turn off almost immediately after turning it on? A problem with this can be the failure of one or more capacitors on the motherboard. This case is quite bearable as they are easy and simple to solder. It is best not to bother with soldering, since capacitors are different. It is better to take the PC to a service where you will not be charged a lot of money for this procedure.
Cooling system problems
The processor needs good cooling, and the more powerful it is, the more serious it should be. For example, an old-generation intelcorei3 is enough for a regular boxed cooler, but if you take one of the top-end i7 6900K, you won't get away with a weak cooler, usually such processors are equipped with water cooling. Also with regards to video cards, the cooling of a powerful video card must necessarily be active, that is, it must be equipped with a radiator and a cooler, and preferably two or even three. Overheating of these components may be due to a cooling problem, perhaps one cooler stopped working, or it got caught on the wire. The situations are different. But what should always be the same is the stable operation of the cooling system, and this applies not only to individual components, but also to the system unit as a whole.
Poor ventilation
The motherboard can easily get warm if the coolers are incorrectly installed in the case or if they are absent. Air currents should be directed to the back of the case, thereby blowing out all the heat from the inside, the loops should not be an obstacle to this, so they must be properly laid, since modern cases make it possible to do this.
Ideally, there should be several coolers, one for blowing in, the other for blowing out. This allows air to circulate evenly in the enclosure, cooling all system components. If one of the coolers does not work well, there is no need to lubricate it, it is much easier to buy a new one.
When assembling the PC, you should not rush, all components must be correctly fixed, the board must be fixed and firmly attached to the case, all wires must be fixed so that they do not interfere with air circulation. By the way, from the visual part, it looks a lot aesthetically pleasing, most likely, seeing your order in the system, many friends will be very surprised at this and think about the same for themselves.
Dust in the case
Every few months, be sure to pay attention to the accumulation of dust in the system unit. The heatsink collects dust very strongly; it also collects on the fan blades, on the board itself. Many people think that dust is completely harmless, but it is not. Its large accumulations significantly impair the performance of the cooling system. Of course, because of this, the board and all parts of the system get hotter. An ordinary user will not be able to fully clean the computer from dust, we advise you to contact the service.
Radiator not installed correctly
Is the board getting too hot? Does the computer shut down by itself? Hangs under load? Check if the heatsink is properly attached to the processor! The heatsink must fit very tightly to it, and a layer of thermal paste must be applied for better heat dissipation.
If the radiator is not properly mounted, you can forget about normal PC operation. The same will happen if the heatsink is not properly fixed on the motherboard chipset, on the video card. What kind of cooling can we talk about if the most important part of cooling is not adjacent to the component cover?
Processor defect or malfunction
There were times when the board gets very hot, but the cooling system works perfectly. This may be caused by a defective processor, or it has worn out over the years of use.
Also, one of the options for overheating can be an increase in the voltage in the power supply, in this case it must be replaced and a voltage stabilizer bought. Unstable operation of the power supply can cause many malfunctions, so the power supply should be of high quality and branded.
Sometimes the problem of overheating may be in the wrong BIOS settings. All this can be easily dealt with by the specialists in the service center. Without knowledge of a computer, you should not engage in self-repair!
The operation of various nodes of a personal computer (PC) is provided using special control schemes. The current level of development of miniaturization of components makes it possible to combine such control circuits in one microcircuit product, called a chip.
There may be several such chips on the motherboard (MP); they are called bridges, by analogy with the transport function of bridges. Traditionally, a chip that works with high-speed PC components is called a northbridge (SM), and all other components are connected to a southbridge (YB).
In this article, we will look at what the north and south bridges are, what role they play in the operation of a PC, where they are located and how to diagnose them.
These devices have their own role in ensuring the operation of certain PC nodes, let's consider what each of them performs.
Northern
The answer to the question, what is the north bridge on a motherboard, in fact, this is the answer, what kind of motherboard we have. The main functions of the motherboard are laid down in it. It provides data exchange between the processor and memory, as well as high-speed external devices connected to the PCI and PCI-E buses.
The functions of the north bridge on a laptop motherboard are similar to its function on a PC board, with the only difference that a laptop video card can be built into it.
Southern
The UM functions are to ensure the correct operation of all other devices included in the PC or connected to it. These include:
- USB devices;
- hard disks;
- various storage media;
- input and output devices;
- sound cards;
- etc.
Where are
These devices are located near the locations of the components they are responsible for ensuring their operation. In the place where the CPU is located, there is also the north bridge, where the periphery is located - the south one.
South bridge
YM is located in the lower right part of the motherboard, as close as possible to the SATA, USB and other peripheral connections.
North bridge
The north bridge on the motherboard is located at the top of the motherboard, as close as possible to the processor and its power supply circuit.
Important! About 10 years ago, almost all of the CM functions were moved to the processor. All modern processors have a built-in memory access controller and a system bus shaper. The need for a special chipset, placed in a separate microcircuit on the MP, disappeared by itself.
Full diagnostics of YM is quite complicated and requires the use of special equipment, however, preliminary diagnostics can be carried out at home.
Consider how to check YM using a minimum of available tools. As such, you can use an ordinary Chinese multimeter. The most common reason for the failure of the UM is the burnout of the power circuits, in which the power signal is "short-circuited" to the common wire.
You can check this by measuring the resistance of the power supply circuits leaving the YM. This is best done on USB connectors. We transfer the multimeter to the resistance measurement mode and measure the resistance between the 1st and 7th, as well as between the 2nd and 8th legs of the USB connector. These legs are always signed, so there shouldn't be any problems.
If YM is in order, the resistance should be of the order of several hundred Ohms, if it is significantly less (units of Ohms or even 0), then YM is out of order.
Checking the North Bridge
Any malfunction of the CM is critical for the operation of the PC, so its diagnosis is elementary: if the computer starts up and starts booting, then the CM works, otherwise it does not. Naturally, the rest of the components (processor, memory, video card, etc.) must be guaranteed to be in good working order so as not to mistake their failure for a false CM failure.
Why bridges are heated and what to do
Any semiconductor components are heated by exceeding the normal value of the current flowing through them. This may be due to an increase in the number of connected devices, the use of both software and hardware overclocking, poor ventilation conditions, etc.
Separately, you should talk about emergency situations. For example, overloads due to improper connection of external devices (too high power consumption via SATA or USB ports, short circuits in these ports, connection errors, etc.). When
when such a situation arises, the time counts for minutes, and often for seconds. Therefore, it is better to simply not allow them.
The south bridge is warming up
This situation occurs quite often, since it is the YM that is responsible for the operation of the entire periphery, moreover, unlike the northern one, to which only the processor, bus and memory are connected, everything else is connected to the southern one.
The best way to reduce the temperature of the UM is to reduce the load on it by disconnecting additional devices, for example, from the USB bus. However, if the tasks of a PC include working with a large number of peripherals, this, of course, cannot be done.
Therefore, you will have to look for another solution. The simplest thing is to replace the radiator located on the YM (and sometimes not replace it, but install it, since the low heat generation on the YM often does not require a radiator at all).
For this purpose, it is necessary to find a radiator of suitable dimensions and install it on the YuM microcircuit using hot melt glue.
Attention! The use of thermal paste, as in the case of a processor or a video card, is not enough, since there are no clips in the fastening mechanism of the bridge cooling system, and the adhesive properties of the paste are not enough to hold the mass of the radiator.
The north bridge is warming up
Very often you have to read on forums and in social media. networks: “Help! The north bridge is getting hot, what should I do? " The answer to this question is very simple: in 90% of cases nothing needs to be done. For SM, working at elevated temperatures is the norm.
It's another matter when the temperature rises so much that it triggers the internal protection and turns off the bridge, and with it the entire PC.
There can be only one solution in this situation: to improve the cooling system of the bridge. This can be done in two ways: by altering the passive cooling system or by installing an active one.
Alteration of the passive cooling system consists in changing the radiator to a more massive one or having a larger dissipation area. This difference is noticeable even visually. The old heatsink should be separated from the chipset, the rest of the connecting compound should be removed and the new heatsink should be glued with hot glue.
If you replace the radiator with a cooler (a heatsink-fan bundle), you can significantly reduce the temperature of the microcircuit. For this purpose, you can use any cooler with a fan diameter from 30 to 60 mm.
In most cases, overheating of computers and laptops is manifested by the following symptoms:
The most important components are processor, hard drive, video card, power supply, motherboard
1.Diagnosing the causes of computer and laptop overheating
1.1. Overheating processor
Signs of the problem: programs freezing, unexpected restart or shutdown of the computer, blue screen. The consequences of this state are the degradation of the chip, the processor can work, but with errors. If the processor has undergone degradation, it will not be possible to repair it, only throw it away.
1.2. Overheating of the video card
The computer freezes while watching a video, after a few minutes of the game, the computer restarts, a blue screen appears, graphic artifacts on the screen, the image disappears during operation, a notification may appear.
As a result of this condition, the components of the video card are threatened with degradation.
1.3. Hard drive overheating
If the hard drive overheats, the computer suddenly freezes, clicks are heard from the system unit, the system does not boot. Typically, these signs appear when overheating has caused irreparable damage. If you want to restore the data that was recorded on the hard disk, you can do this only through the service center. The hard drive itself cannot be repaired, but the information can be copied to another medium.
1.4. Power supply overheats
Dangerous symptoms appear: during operation, there is a burning smell, shutdown immediately after start-up, an unexpected restart occurs, games or videos freeze. The consequence may be the failure of the components of the power supply, but repairs to a service center will cost you inexpensively.
1.5. The chipset on the motherboard is overheating
If the chipset on the motherboard has overheated, this manifests itself as follows: the keyboard, mouse disconnects, USB fails, there is no connection to floppy drives and hard disk, the computer freezes, unexpected reboots occur. As a result, the chipset can degrade. If you do not monitor the temperature of the motherboard, you will subsequently have to buy a new one, since repairs are very expensive.
1.6. Overheating of other computer components
In addition to the above, various batteries on the motherboard are heated. For effective cooling, they must be equipped with radiators. But some manufacturers, in order to save money, do not do this, hoping that the motherboard will work exclusively in normal mode. Therefore, at least one fan must be running to cool the components by natural air movement.
1.7. Reasons for computer braking due to overheating
Most often, computer overheating is manifested by its deceleration during operation. Usually this symptom is not visible immediately, but some time after turning on the computer. At very high temperatures, the processor does not work efficiently as it tries to lower the temperature. This process is called throttling. Depending on the model, the permissible processor temperature ranges from 65 to 80 degrees.
Throttling works on modern processors and video cards. So if the games freeze or slow down, it is most likely overheating.
1.8. Causes of computer restart due to overheating
Windows is a complex system. If once the processor issued an error during calculations, then everything is violated. As a result, a BSOD crash will occur, if more clearly - "Blue Screen of Death".
BSOD is a serious error that cannot be ignored. By default, the system is configured in such a way that when a BSOD is detected, the PC reboots itself. Thus, if overheating occurs, a blue screen appears and the computer restarts. However, the "blue screen of death" may just hang. The reboot process after the appearance of BSOD is disabled as follows: through the Control Panel, go to the System, then to Advanced system parameters. In them, open Startup and Restore - Options, from the Perform automatic restart item, you need to uncheck the box and confirm your decision.
In fact, there are many reasons for the appearance of BSOD - malfunctioning drivers and programs, errors on the hard disk. 1.9. Computer gets hotter over time - why
One of the reasons is the amortization of cooling components and dust. To clean the heatsinks and other components of the computer, it is advisable to use fans that suck in the deposited dust. Overheating also occurs due to a large accumulation of dust.
Over time, fans wear out, as a result of which they can constantly make noise, spin at a slower speed, or stop altogether. The thermal conductivity of the thermal interface deteriorates. Thermal pastes and thermal pads, which provide high-quality heat transfer from the processor to the heatsink, require cleaning and replacement.
2. We measure the temperature
There are many sensors inside the computer. They measure component temperature, voltage, fan speed. Their exact number differs depending on the components and their connection options. For example, a cooler with a rotational speed meter can be connected to both the motherboard and the power supply unit (PSU). Otherwise, the speed cannot be measured.
2.1. Open Hardware Monitor
The most convenient utility for determining the temperature of computer components is Open Hardware Monitor. It is able to detect a variety of sensors, can show the temperature of the "hardware" of the computer, voltage and frequency.
You can download the program for free from its home page.
2.2. Temperature measurement errors
The sensors in the computer are not calibrated. Accordingly, the error between temperatures can be several degrees. For example, a video card heats up to sixty degrees, but the maximum indicator for it is seventy. Games start to slow down only after a while. Therefore, the sensor does not display the actual temperature, and there is overheating.
2.3. How to check CPU temperature
Temperature sensors can be located in different ways. Their location is related to the processor model. For example, an Intel Core i7-2600K processor has four physical cores, so there are five temperature meters: one for each core and one for each motherboard.
To find out the CPU temperature, look at the CPU Core item, if there is one. To identify overheating, you should load the processor with a serious task and check the temperature in the load. For this, new games are optimal. Play for half an hour and then watch the Max column in the program. To determine the maximum temperature of your processor, look for information in Yandex or another search engine. If you don't know which processor you have, the program shows the model next to the processor icon.
2.4. How to check the temperature of a video card
The temperature of the elements of the video card can vary, depending on the load. Measurement of the maximum temperature will help determine overheating. Therefore, the video card must be loaded. An easy way is to run the game and Open Hardware Monitor at the same time. In the Max column you can see the maximum temperature.
Usually a video card temperature of up to sixty degrees is considered normal. In some cases, it can go up to ninety degrees, but specific indicators need to be clarified. The reason for overheating of the video card can be braking and unexpected restart of the computer.
2.5. How to check the temperature of the motherboard
Temperature sensors can be found in the motherboard section. All computers have different boards, the number and names of sensors also differ. But none should exceed fifty degrees.
And in some cases this is a lot. In the manual for the motherboard, you can find information about the maximum allowable temperature for the chipset.
2.6. How to check the temperature of the power supply
In the power supply, there can be sensors only for checking the fan speed, so that it does not make noise without load. Therefore, you cannot programmatically measure the temperature of the power supply. You should touch the case of the system unit with your hands. If it is hot or smells like burning, burnt plastic, this is overheating.
3. What to do in case of overheating
If you overheat, you need to change the thermal paste and clean the computer from dust. This must be done correctly. If you do not have relevant experience, it is recommended to use the services of a service center. Laptop under warranty will be cleaned from dust in an authorized center free of charge. If there is no service center, you can return it back to the store with a complaint about overheating. In this case, they will perform the cleaning themselves. It is advisable to copy all the data from the laptop, since the service center can format the hard drive. In addition, document the transfer of the laptop for diagnostics.
It's the same with a desktop computer. The overheating problem should be dealt with by the store where the system unit was sold to you. Whether there is dust or not, overheating must be removed to avoid breakage. In addition, you can clean your computer yourself, but without proper knowledge and care, there is a high probability of breaking something.
3.1. Self-cleaning computer
If you are poorly versed in the location of computer parts, you should not disassemble it yourself. If you find a malfunction, you still have to carry it to a service center.
If you are removing the cooler, then be sure to apply thermal grease between the processor and the heatsink. You can use a cheap KPT-8, which is sold in any specialty store. You should not collect and reuse the paste that was, firstly, over time, it loses its properties to effectively conduct heat, and secondly, when removing the cooler, dust falls on the paste. Therefore, you will have to spread a new one. The layer should be thin, not flowing beyond the surface of the cover and processor. Lack of paste will not allow high-quality heat dissipation.
Instead of thermal paste, developers can use thermal rubber bands. In some cases, they are much more effective, for example, if the distance between two elements is more than a millimeter, the parts cannot snuggle against each other. This is especially common in laptops.
To cool the hard drive, you can place a fan on the front of the system unit, usually there are brackets for this. Vacuuming computers and laptops is not advisable. One of the reasons is inefficiency. Also, due to the strong air flow, dust gets into hard-to-reach places and it will be impossible to get it.
4. About fans and coolers
A cooler is a symbiosis of a radiator and a fan. This device removes heat with greater efficiency. Its location is video cards, processors, motherboard chipset. Conventional fans (without a heatsink) are located in the chassis and power supply. Since a stream of air is enough for certain components for cooling.
Cooling can also be passive - only the radiator works, the heat from which is removed due to the movement of air inside the system unit. This is often used on low-power video cards. Modern motherboards also only have passive cooling. But it is useless if there is no air movement inside the computer case. Therefore, with passive cooling, at least two fans must be installed in the case - one for blowing out, the other for blowing.
All more or less literate users of PCs and laptops have probably heard of such concepts as the south bridge. However, it is one thing to hear, and quite another to understand what it is and what it is for. When these components fail, the repairmen are limited to a faceless phrase like "North / South bridge burned out, needs replacement". And no one will bother to explain to the poor user what exactly happened to his computer. And to know this is very useful. Therefore, let's look at this topic in this article.
What is the South Bridge?
The south bridge of a motherboard is a controller that is responsible for the operation of some important components of the computer. It controls the operation of USB ports, PCI slots, power supply, DMA controller, interrupt controller, real time clock, sound controller and other important components. Without this component, normal computer operation is impossible. It simply will not turn on if the bridge suddenly fails. Therefore, you need to carefully monitor it.
Of course, if the south bridge of the laptop fails, then it is not as fatal as in the case of the north one, but it is still unpleasant. After all, then the PC or laptop simply will not start. But there are no problems with diagnostics. It is immediately clear what burned out. But let's move on to this very diagnosis and analyze how to understand that this particular bridge has failed.
Troubleshooting
As a rule, diagnosing a malfunction is the first step towards understanding the problem and thinking about what to do next. How to understand that the south bridge "ordered to live long"? Very simple. In most cases, the computer simply does not turn on and beeps disgustingly. But it all depends on the degree of damage to the controller. In the case of laptops, USB ports, touchpad and other peripherals, which are entirely dependent on this bridge, may not work.
Also, a symptom of a malfunction of this particular element may be an incorrect global time in the BIOS and the operating system itself. The option with complete disappearance of sound is not excluded. Even the fact that the south bridge is warming up above the permissible temperature can be a very disturbing symptom. This can only mean one thing: very soon it will burn out. Therefore, urgent action is needed.
Breakdown reasons
There can be many of them, but the most common is overheating. The Southbridge is essentially a chipset. Therefore, he needs high-quality cooling. If the cooling system of a PC or laptop is malfunctioning, it is very likely that the controller will burn out. Physical damage is also very popular. A small blow in the right place is enough - and the fragile structure of the chipset will be irreparably damaged. And this is a direct path to the service center. You can't do without it.
There is also a very high probability of liquid getting on the motherboard in the area of \u200b\u200bthe south bridge. One drop is enough for a short circuit to occur. The controller will burn out very quickly. Another common cause of failure is chipset defects. But it is very easy to check, as manufacturers post a list of defective controllers. They will break anyway. And it doesn't matter if it is the south bridge or the north one.
Repairs
The trouble is that the repair of such a component is impossible. Only the replacement of the south bridge will help. The fact is that a person cannot repair a chipset, because it was created by high-tech robots. The person lacks precision. And no one has such tools. So, you still can't do without a visit to the service center to the repairmen. Just do not give your computer into the hands of any "craftsmen" who promise to change the bridge for half the price. Such a would-be specialist can easily kill not only all bridges, but also other very fragile computer components. Please contact professionals only.
If you have a deliberately defective controller installed in the motherboard in place of the south bridge, and the manufacturer confirms this, then you can change it immediately after purchase. It will not cost you a penny, since this is a warranty case. You will simply have a chipset installed without a defect. It is better not to delay and immediately contact an authorized service center, because the consequences can be very sad when postponing this matter indefinitely.
Prevention
In order for the south bridge of the motherboard to work for a long time and without any problems, you need to follow very simple rules for operating a computer or laptop. Firstly, do not neglect cleaning the device from dirt and dust. Even a small layer of dust can damage the bridge controller. Coolers clogged with dirt and ventilation slots can easily lead to overheating and failure of the element. Secondly, do not expose the device to physical stress. The slightest damage can have the most dire consequences. This should not be neglected, because you can lose not only the south bridge of the device.
Third, do not have the habit of eating or drinking near your laptop. Spilled tea and coffee can have fatal consequences. One drop of any liquid is enough for a short circuit to occur and the south bridge is out of order. Also, don't take your laptop to the bathroom with you. Even if you will not touch it with wet hands, nobody canceled the condensation. Fourth, keep pets away from the laptop or PC. Wool clogs vents, coolers and other components of the cooling system very quickly. Hence, overheating and failure of the south bridge. Use your device carefully. And then you won't have any problems.
Conclusion
So, above was considered such a component of the motherboard of a computer or laptop, as the south bridge. Now you know what he is responsible for. Although this controller is not as important as the northbridge, you won't be able to turn on your PC or laptop without it. In order for this component to be safe and sound, it is enough to follow the simple rules of safe computer operation. Then your laptop will serve you faithfully for a long time. Now you know how to diagnose the failure of this particular system component. And never refer to "craftsmen". It is better to entrust the gadget to professionals.

Eliminating the causes of overheating of the processor, video card, motherboard, etc.
Read about how to find a component that is overheating.
I will describe the causes of overheating in descending order of their likelihood, and the remedies, starting with the processor.
Reasons for processor overheating and their elimination:
1. The main reason for the processor overheating - the heatsink gets clogged with dust, air exchange becomes difficult and, as a result, overheating - you need to clean the processor heatsink from dust, you can do it with a vacuum cleaner but very carefully and only when the computer is off.
2. If the heatsink is shiny, but the processor is still overheating, then the thermal paste is probably dry, you need to carefully remove the cooler from the processor, remove the old thermal paste from the cooler and processor, and apply a new one. You need to apply very little new thermal paste, and keep in mind the coolers on motherboards with a 775 socket, they are very inconvenient to remove, their legs break off, and it is difficult or impossible to install such a cooler back. Also, when installing a cooler, there is a risk that it will be installed crookedly (visually it is not noticeable) and the processor will overheat.
3. If, after completing the first two steps, the processor still overheats, then a slight decrease in the processor voltage in Bios will probably help, it will have to be selected experimentally.
Causes of overheating of the video card and their elimination:
- The main reason for overheating of video cards is the drying of the thermal paste (relevant after 3-5 years of operation) and the ingress of dust and lint into the radiator, as a result, the fan works at 100%, and the temperature does not drop. Cleaning the radiator and fan blades from dust is the first thing to do, if this is not enough, replace the thermal paste.
- The second fairly common reason for overheating of video cards is a lack of cooling, video cards are becoming more powerful every day, and their cooling systems are often not designed for high loads (especially for inexpensive models), often due to high load, a regular fan fails (usually starts to make noise , but it happens that it jams), and the video card starts to overheat. It can be repaired either by replacing the fan with the same one - I have never done that, finding the same fan is still a problem, most often I take a large fan like this:
And using rubber bands for money, I attach it to the video card, pay attention to the arrows indicating the direction of the air flow, they should be directed to the radiator of the video card. Thus, a quiet and reliable cooling of a video card is obtained, which has already been tested on more than one computer. It should look like the picture:
This method has a small drawback, after about six months or a year, the gum begins to dry out and fall apart, so you need to change them from time to time, or replace them with something more reliable, for example, a piece of wire from a untwisted twisted pair.
Reasons for overheating of the motherboard and their elimination:
1. On the motherboard, as a rule, the south or north bridge overheats, this happens rarely, it is solved by installing additional fans, usually a place is reserved for them on the back wall of the system unit, they must be installed for blowing.
Hard drive overheating reasons:
1. Lack of cooling. It is advisable to install the hard disk in places where there is air movement and preferably at the bottom of the system unit, if this is difficult, then you need to install a special fan for hard disks.
2. High load on the hard drive, if you constantly use the hard drive, then take care of its additional cooling, in fact, the durability and reliability of hard drives strongly depends on their temperature during operation, hard drives that regularly heat up over 50 degrees are unlikely to become long-livers, it is optimal the maximum temperature of your hard drive during operation did not exceed 45 degrees, ideally - the temperature of the hard drive is in the range of 35-40 degrees.
