The cooler in the laptop began to make a lot of noise. HP Notebook PCs - Fan is Noisy and Constantly Spinning, PC Temperature is Higher Than Normal

If your laptop is very noisy and you feel like it was quieter before, then there is a possibility that your laptop is overheating. Whether this is true or not, you can find out for yourself. This is what will be discussed in this article.

What to do if your laptop is very noisy?

Diagnosis of the problem

The first thing you need to pay attention to is whether the laptop turns off spontaneously or not when you are working on it. If yes, then most likely the laptop is overheating and your problem requires an urgent solution. For complete confidence, you need one that allows you to read information from your laptop’s temperature sensors and help you make an assessment on the issue that has arisen.

So, we launch the program and wait a few seconds until the information is displayed. First of all, we are interested in the processor sensor (CPU). In addition to the temperature, you can also see the model of your processor.

Acceptable values are individual for each processor. You can find out the exact information on the website if you have an Intel processor, or on the website if you have an AMD processor. But if you don’t want to bother yourself with this information, just know that at rest, when you only have the desktop on your screen and nothing unnecessary is running, the temperature should be 45-55°C, depending on the individual characteristics of each processor. But 60°C and above is considered high for a calm state of the system.

Therefore, when conducting analysis, you need to make sure that the processor is not loaded with anything. It happens that you have closed all visible programs, but the processor is still under load. You can see the processor load through the task manager by right-clicking on the taskbar and selecting “task manager” in the context menu, or by pressing CTRL+SHIFT+ESC.

Depending on what version of Windows you have, you may see one of the two most common options.

Possible causes of overheating

The most common cause is accumulated dust in the cooling system. As a result, the fan, no matter how fast it spins, cannot provide sufficient cooling. Everyone faces this sooner or later. Users who rarely turn on their laptop encounter this problem less often. Well, those who rarely do wet cleaning at home, put a working laptop on the sofa and live with two cats will most likely encounter a problem in less than a year.

How bad is it?

The short answer to this question is bad. The fact is that the fan, the noise of which bothers you so much, is the first step in protecting your laptop from overheating. Next, the processor protection mechanism from thermal damage comes into force ( throttling) , by skipping clock cycles. In simple terms, the processor clock speed is reduced, which leads to a slow laptop. But this is not always enough, and when the temperature reaches a critical level, the last stage of protection comes into force - shutdown. But only the processor is equipped with such protection. The chipset and video chip, without such protection, remain vulnerable to overheating and often fail when reaching a critical temperature.

What to do?

You have two options. The first, more reliable one is to seek help from a specialist. Preventive cleaning is several times cheaper than repairs to replace a burnt chip.

The second way is to do the cleaning yourself. But for this you will need a set of screwdrivers, good thermal paste, possibly a thermal pad, as well as access to the Internet.

Find the model name on your laptop case. For example, you have HP pavilion dv6 . Just search Google or another search engine for “cleaning an HP pavilion dv6 laptop” and you will find instructions and even a video on how to disassemble and clean your laptop. But first, I advise you to review the instructions to the end before starting, in order to assess the complexity of the procedure and your capabilities.

Conclusion

Now you know what to do if your laptop is very noisy.

In conclusion, I will say that fan noise is normal. By throwing hot air outside, the heating elements of the laptop are cooled. But if the cooling system becomes clogged with dust, or some of the processes in the system constantly load the processor at 100%, then this leads to an increase in temperature and, as a result, high fan speeds. Use the method described in the article to determine whether there is a problem and whether something needs to be done about it.

As you know, any technology is not particularly durable, and modern computers or laptops are no exception. Over time, many owners of laptops begin to notice the appearance of overheating in them. Questions immediately arise about why the laptop makes a lot of noise and what causes the intense heating. In general, there is a feeling that something is wrong with the technology. In the simplest case, there are no visible malfunctions in the operation of the device, but sometimes you can even encounter the appearance of blue screens. And this is already a reason to think about the possible reasons for this phenomenon and possible ways to troubleshoot.

Let's find out what exactly could be the root cause of the laptop making a lot of noise or overheating unnecessarily, and let's decide what measures can be taken to get rid of possible failures. As a rule, this does not apply to new equipment just purchased in a store, but rather only applies to those devices that have been in use for a long time. If you notice such phenomena immediately upon purchase, it is likely that you are dealing with a manufacturing defect. However, if you purchase a laptop secondhand, it is quite possible that its configuration has been enhanced, and the cooling system simply cannot cope with the functions assigned to it, which will be discussed separately.

Why is the laptop very noisy: possible reasons

As for the main reasons for this phenomenon, for some reason many users usually attribute them exclusively to physical problems, often forgetting about the software impact on some of the “hardware” components of the computer system. Among the most common reasons that a laptop begins to make a lot of noise and overheat, most experts name the following:

clogging of the device with dust and foreign debris;
failure or incorrect setting of fans (coolers);
enhanced configuration incompatible with the cooling system;
constant use of high power consumption (high performance) mode;
possible problems with the hard drive and its components;
incorrect operation of the optical drive or the presence of a disc in it;
software failures due to outdated device drivers;
viral impact.

Of course, this is not all that could, in theory, provoke the appearance of such undesirable side effects, since physical damage to the equipment installed in the laptop cannot be discounted either. In addition, many may immediately have doubts about the impact of viruses on the system. The issue is controversial, and we will dwell on it separately. In the meantime, let's look at some of the simplest methods for eliminating such problems.

What to do if the laptop is very noisy: the simplest solution

It goes without saying that the most common situation with the appearance of strong noise or overheating is associated with a dirty laptop. This, by the way, applies not only to small dust particles getting on the fan blades, but also to settling on other components installed on the motherboard, as a result of which the cooling air flow simply does not reach them.

Thus, if you notice that the laptop is heating up and the cooling system is making a lot of noise, which is usually accompanied by hot air escaping through the holes on the side walls where the coolers are located, the first step is to disassemble the laptop (if this is possible, of course, you know how do, or the laptop is not under warranty), and then thoroughly clean its “insides” from dirt and dust.

To disassemble the device, it is best to use special sets of tools that can be purchased in specialized stores, and for cleaning, special vacuum cleaners, tampons and wet wipes are suitable.

Identifying problems with the cooling system

Naturally, it often happens that a laptop makes a lot of noise only because the fans are not operating in normal mode, which causes the same processor or graphics accelerator to overheat. In this case, it is necessary to monitor the temperature.

Windows tools are not suitable for this, so it is best to use third-party utilities like AIDA64, HWMonitor and their analogues, which have software sensors for recording the status parameters of a particular component of a computer device. Please note that in normal mode, short-term achievement of the maximum temperature threshold is allowed, and each hardware manufacturer includes a certain “safety margin” in their devices. Look at the maximum performance. If the heating reaches a safe point, there is no particular cause for concern. But if there is a constant excess of the permissible threshold, emergency measures will have to be taken.

Adjusting cooler settings in primary I/O systems

So, you have determined that the laptop is noisy and gets very hot, exceeding all permissible standards.

To lower the temperature in the absence of special software, you can use the settings of the primary systems (BIOS/UEFI), in which you need to find a section or item like Fan Optimize, Q-Fun, Fan Monitor, CPU Fan Control or something similar, and then, if possible set other parameters or use automatic optimization. But many primary systems do not have such tools, so it is often recommended to either perform a full factory reset or completely update the BIOS by downloading and installing the latest firmware for your laptop model. In the case of UEFI, everything is simple, since you can run the update directly in the Windows environment, but with the BIOS you need to be extremely careful, and without special knowledge you should not do such things yourself.

Adjusting fan speed in special programs

If the fan on the laptop is very noisy, but there are no settings for it in the primary system, you can use special programs. One of the most famous, powerful and popular is the SpeedFan program.

In it, you need to slightly reduce the cooler rotation speed, taking as a basis a step of about 5% or even less. The reduction must be carried out until extraneous noise in rest mode, when no application is running, disappears.

What to do if overheating is detected?

It is often possible to observe that the laptop makes a lot of noise when playing games or when working with multimedia programs. In general, this is a normal phenomenon, since most modern software of this nature places an increased load on the central processor, as a result of which additional reserves of the cooling system are used. But the laptop may have an outdated CPU, graphics adapter, or lack of RAM. In such a situation, the equipment simply cannot cope with processing the increased volume of calculations. To fix the problem in the simplest case in the same games, you can use lowering the FPS level or screen resolution, turning off texture detail, etc. Of course, the picture quality will suffer a little from this, but the noise with overheating will disappear, and the laptop itself will not fail prematurely.

Another situation is that the standard equipment has been changed, and the cooling system is not designed for upgrading.

The example in the image above shows the configuration of the DELL Latitude E6520 laptop, which came with only 4 GB of RAM, but it was increased to 8 GB by installing additional slots. It is not surprising that the cooler on a laptop makes a lot of noise only because it is not designed for such loads.

Very often, game lovers, in order to play them more comfortably, install a special high-performance mode, which can automatically provoke an increased load on system resources. This leads to the laptop making a lot of noise and heating up. In Windows 10, when you turn on Game Mode (Win + G), this power plan is activated automatically. To reduce the load a little, go to the power settings and set the balanced mode.

If this does not help get rid of side effects, use the energy saving mode. However, when setting such parameters, the game may begin to slow down. If nothing helps at all, but you don’t want to give up your favorite games and programs, it’s best to replace the processor, video card and RAM, naturally, not forgetting about the cooling system and the corresponding power supply model. As is already clear, such pleasure does not come cheap. In addition, the new processor may not fit on the old motherboard, so you will have to change it too, but in the end it will turn out that it would have been cheaper to buy a new laptop.

Eliminating optical drive noise

It often happens that a laptop is very noisy only because there is a disk in the optical drive, when accessed, noise appears from its spin-up. In addition, the disc may have scratches or physical damage, and therefore unwinding and attempting to read information takes a very long period of time.

Troubleshooting hard drive problems

Finally, one of the most unpleasant situations can be called gaps in the operation of the hard drive, which can be associated with the presence of errors on it, and with the fact that the hard drive begins to “crumble”, becoming unusable, and with incorrect power parameters.

To identify possible failures and troubleshoot some problems, you can use the most common “Task Manager”, determine which process loads the hard drive the most, and then forcefully terminate the active service. It would also be a good idea to check the disk for errors using system utilities like HDDScan or quietHDD. However, if serious physical problems are detected, it is strongly recommended that the hard drive be replaced. The best option would be to purchase a modern solid state drive (SSD). Such disks will definitely not make noise.

Updating hardware drivers

Software components in the form of device drivers can also cause such situations. This applies to a very high degree to video cards if the laptop has a discrete accelerator equipped with a powerful graphics processor and its own cooling system. And outdated or incorrectly installed control software can provoke malfunctions, which may result in noise and overheating. You should not update drivers using the operating system.

It is better to use automated utilities like Driver Booster, which will find the necessary software on the Internet, directly on the manufacturer’s website, download it and install it without your participation.

Can side effects occur with viral exposure?

Unfortunately, the presence of viruses in the system cannot be ruled out. Many people believe that viral threats cannot directly affect hardware. This is not entirely true. Through control drivers, any equipment can be disabled. In this regard, it is enough to recall a virus that once “walked” on the Internet, which, when introduced into a system, focused maximum energy at one point on the screen, after which the cathode ray tubes of old monitors simply burned out. To prevent the penetration of threats, you cannot rely only on a standard antivirus, since it may not detect some types of threats. At the very least, for prevention, scan your laptop with third-party portable programs at least once a week.

Epilogue

In conclusion, it is worth noting that these are not all possible situations in which a laptop is noisy or overheats. In fact, there may be much more of them, and they are associated with some other factors. Just in case, it doesn’t hurt to “ring” the entire motherboard for the voltage supplied to the devices; sometimes it is necessary to replace the thermal paste on the processor or install another power supply; in addition, you can upgrade the cooling system by purchasing a special cooling pad to reduce heating, etc. . In general, there are enough options.

Many laptop users experience annoying noise coming from their devices.

It can be especially noticeable in the summer, when the heat causes components to overheat and cooling systems to operate at increased speeds.

So people have to go to the Internet and look for an answer to the question: the laptop is making a lot of noise, what should I do?

But before we begin to consider ways to eliminate the problem, we first need to understand the causes that provoke it.

Causes of noise in a laptop

Overheat.

The most common phenomenon in laptops.

The form factor of such devices simply does not allow for truly effective cooling to be installed there, so the temperature often rises to a critical level, sensors inside read all this and increase the rotation speed of the coolers.

Accordingly, an unpleasant hum begins to come from the case. Overheating is also caused by dust accumulating inside, which interferes with heat removal and normal air circulation.

Damage to the cooling system.

The most common is banal wear of bearings, leading to radial runout and, as a consequence, contact between parts that should not be in contact in any way.

A slight tilt, and now something somewhere is rubbing, grinding and making other unpleasant sounds.

Incorrect software settings.

Illiterate users, having tinkered with Bios settings and special programs in an attempt to overclock the power of their device, often then begin to sincerely wonder why the fan in the laptop is noisy.

And the reason is simple - the hardware is not designed to work with such installations, it heats up and forces the coolers to spin at maximum speed.

Malicious code.

Various viruses are often able to get into system processes and use hardware resources for their own purposes (the same miners who produce cryptocurrency for their owners).

So it happens that users are surprised - they seem to be sitting and just typing in Word, but the laptop is making a loud noise, as if they are playing the latest action game on Ultra settings.

Diagnosis of problems

Determining the causes of noise is not difficult, especially when it comes to overheating.

The hum from the case is not the only symptom - freezing and braking are observed, the device can spontaneously reboot if it is used for some time in a resource-intensive application or computer game.

This can happen due to the presence of dust and dirt inside the cooling system, dried out thermal paste, or difficult air exchange. To verify this, just climb inside the case.

It is much more difficult to determine the problem if the cause is software in nature.

Install a reliable statistics collection program on your system, such as Everest. It will clearly show at what specific settings the laptop’s hardware operates (frequencies, voltage).

If you changed something before discovering the noise problem, it is better to return all parameters to standard/optimal values.

Quick cleaning of a laptop cooler fan

So, having gained an idea of the main reasons that cause unpleasant and annoying noises, you should begin to eliminate them.

Let's start with the most obvious - if the cooler on your laptop starts making noise, you should inspect and clean it.

Anyone can handle this, but do not forget that any penetration into the case will result in the loss of the manufacturer's warranty. So, the sequence of actions is as follows:

The quick cleaning procedure described above does not always help - often more serious measures are required, requiring complete disassembly, replacement of thermal pads, thermal paste, etc.

All this is written in detail in the article “Cleaning a laptop from dust.” We recommend that you familiarize yourself with it.

Cooler speed adjustment programs

If the laptop cooler hums even in a calm state, but there are no obvious signs of overheating, this may indicate that the blade speed is too high.

Fortunately, it can be easily reduced using one of the programs described below:

You can also try to adjust the cooler speed through the BIOS.

To do this, when turning on the laptop, press the Del key (some manufacturers use other keys), and then find the Power or H/W Monitor Configuration section in the window that opens.

They should contain an item responsible for the speed of the fans.

Set the percentage value you need, then save the changes and start the system. But do not overdo it - if the speed is minimal, this can lead to overheating and failure of components.

Other methods to prevent fan noise

In addition to cleaning and monitoring the rotation speed of coolers with special software, there are several other tools that can help owners of noisy laptops in certain situations.

Cooling pads

Laptop stands with a built-in cooling system come to the rescue if the coolers built into the device cannot cope with the tasks assigned to them.

and they have one or more additional fans installed that blow over the laptop body and thereby lower its temperature. The quality of airflow greatly depends on the manufacturer and model of the gadget.

If you buy a cheap budget stand, you are unlikely to get rid of overheating. In addition, it may well aggravate the situation by further increasing the noise level.

DeepCool performed well in the budget segment, and CoolerMaster performed well in the expensive segment.

Laptop BIOS update

When the fan in the laptop is very noisy even when turned on, this may be a consequence of incorrect settings in the BIOS.

That is, the developers themselves made mistakes that did not allow the system to normally read readings from temperature sensors and control the rotation speed of coolers.

Some BIOS versions do not even provide users with manual configuration options. Therefore, it is recommended to go to the manufacturers' official page, find the latest BIOS version for your laptop model and install it following the instructions posted there.

Don't forget to remove the disc from the drive

It seems like a small thing, but it can greatly affect the noise level. A working CD/DVD drive creates vibration, which is transmitted to the rest of the device.

Such an impact will obviously not benefit them, so it is better not to keep disks in the drive, but to use more modern drives (flash drives, external HDD/SSD). They not only do not emit noise, but are also more compact and resistant to damage.

That's all. If after reading the material you still have any questions or would like to supplement it with useful information, do not hesitate to write in the comments!

Ordinary users are increasingly choosing not desktop personal computers, but laptops. There are many reasons for this. First of all - ease of transportation, compactness and at the same time excellent performance.

But the distinctive feature of this type of technology is its unique design. The consequence is the occurrence of some rather specific malfunctions. The first signs of their appearance are excessive heating of the case and extraneous noise during operation. The reasons for such malfunctions may be different. They need to be eliminated in a timely manner. Next, you will find out why the laptop gets very hot and makes noise during operation, and what to do in such a situation.

Reasons why a laptop makes noise and gets very hot during operation

The appearance of artifacts, distortions on the screen during operation of the laptop, as well as heating of the lower part of the case is a sign of serious malfunctions. It is worth eliminating them as quickly as possible, since overheating of the processor, video card or other components can lead to their failure.

An increase in temperature inside the case occurs for the following reasons:

the thermal paste has dried out or for some other reason lost its properties;
the presence of a very large amount of dust inside, which can cause noise.

In both cases, disassembly of the case will be required. Thermal paste is present on the radiator for cooling the video card, as well as the central processor. To replace it you will need a plastic card and a new paste. If you do not have experience with replacement, you should contact a qualified specialist. Such an operation has its own specifics.

A working laptop is usually cooled not only passively, but also actively - using coolers. They are the main cause of dust appearing inside the case. Also, plastic and other PC parts create static electricity around them - which also attracts small particles, dust and other things. Most often, all this accumulates on the cooling grilles, which impedes air circulation. It is necessary to remove dust in a timely manner.

Sometimes laptops that are used continuously begin to make sounds that are uncharacteristic of normal functioning. The reasons for this may be the following:

hard drive failure;
malfunction of coolers.

In the first case, the noise problem can only be resolved by replacing the hard drive. Such devices have some operating life. They also sometimes fail due to mechanical damage. For example, if the laptop is dropped or knocked.

Extraneous sounds are often produced by the cooler. During prolonged operation, the grease on the bearings may dry out or some foreign objects may get inside the housing. As a result, the fan may grind or rattle when rotating. To correct such problems, you will also need to disassemble the housing and lubricate the bearings. This operation should be carried out as carefully as possible. Bearings are lubricated using special Vaseline-based compounds.

What to do if your laptop gets very hot and noisy?

If the first signs of the malfunction in question are detected, their cause should be eliminated immediately.
If you have no experience in repairing laptops, it is advisable to contact an authorized service center. Since damage caused by an inexperienced person in this area can be serious and lead to the need to replace individual components of the laptop.
The most expensive components of laptops are the central processing units, hard drives and video cards. Timely repairs at the first signs of overheating, noise and other malfunctions will save the owner a significant amount of money.

Most computers are equipped with an air cooling system. This means that its parts are cooled using air flows created by fans. Sometimes troubles happen and disturbing noises appear. In this article, I will tell you why the cooler in a desktop computer and laptop makes a lot of noise, and how you can get rid of it.

You can often come across advice that if the cooler is very noisy, you need to reduce its rotation speed using special programs or through the BIOS. However, I would not recommend this to non-experienced users. A decrease in speed can lead to overheating of parts, resulting in death and expensive repairs.

Reason 1: Dust in the cooling system

If the cooler is making a lot of noise, then open your computer and take a look at the dust that has accumulated there. This is what most often causes the noise. Thus, dust settled on the fan blades changes its centrifugality, causing it to hum. Additionally, if dust disrupts the cooling airflow, the cooler has to spin faster to keep parts at normal temperatures.

Dust can be removed from a desktop computer or laptop using a small vacuum cleaner, hair dryer or brush. You can also use a cotton swab soaked in alcohol to remove old hardened pieces of dust.

Be careful when cleaning dust. The computer must be disconnected from power at this moment. You cannot make rough movements so as not to damage anything inside. When using alcohol, do not allow it to come into contact with the boards. After treating with alcohol, the computer can only be turned on after 10-15 minutes.

Reason 2. Unlubricated cooler

If the cooler is very noisy, the reason may be the fan itself. If cleaning the dust does not help, you should lubricate the bearing with oil. You can use machine oil for this.

To lubricate the cooler, you cannot use car or vegetable oil, and especially Vaseline.

To lubricate the cooler, you can use a syringe with a needle or cotton wool. In most cases, you don’t even have to remove the fan itself, but simply tear off the decorative sticker in the center - from here you can gain access to the bearing.

Reason 3. Broken bearing

If a fan's bearing is worn out, it will make noise. As a rule, accompanying symptoms are the cooler not being centered and the blades brushing against its body when rotating.

In this case, if the cooler makes a lot of noise, that’s still good. In the worst case, it will stop and everything will overheat. Therefore, it is better not to wait for this and just change the fan.

The same reason can include cracks in the fan blades. If they are detected, you will also have to change the fan. True, this rarely happens.

Reason 4. Poorly secured parts

It is possible that it is not the cooler that is making noise in your computer, but something else that is susceptible to vibrations from the rotation of the cooler. For example, if a hard drive or disk drive is poorly secured in the system unit, they will vibrate and make unpleasant noise. A similar situation can occur if the screws in the laptop case or parts are not tightened properly.

What can I say? It happens that a cactus in a pot, placed on the case of the system unit, begins to vibrate so strongly that it interferes with work.

Which noise is normal and which is abnormal?

If the cooler is noisy, first understand how loud it is.

The fan noise should be similar to the sound of a slight draft. A little noise is normal.
If during games or when running some heavy programs the cooler makes a lot of noise, then this is normal, since the processor is under more load and the fan starts spinning faster to cool it (although it won’t hurt to clean the dust if you haven’t done this for a long time) .

And remember that the system unit is noisier than any laptop. So, if your friend with a laptop has almost no noise, then do not rush to look for problems in your system unit - it should make more noise.

How to find out which cooler is noisy

With a laptop, everything is simple - in the vast majority of cases there is only one fan. But with a desktop computer it’s more difficult - at least two fans: on the processor and in the power supply. And maybe more.

If the cooler in the system unit is making a lot of noise, then in most cases it helps to find out the source by simply opening the case, listening and understanding the direction of the excess sound. If this does not help, you can try a risky method - gently and briefly (momentarily) stop (slow down the rotation) each of the fans by pressing on their center with your finger. However, this can be dangerous for the hardware, so just try to listen.

When the faulty cooler is found, begin treatment.
