As you know, any technique is not particularly durable, and modern computers or laptops are no exception. Many laptop owners over time begin to notice the appearance of extraneous noise and overheating in them. Questions immediately arise about why the laptop is very noisy and what causes a lot of heat. In general, there is a feeling that something is wrong with the technique. In the simplest case, there are no visible malfunctions of the device, but sometimes you can even see the appearance of blue screens. And this is an occasion to reflect on the possible causes of this phenomenon and possible methods of troubleshooting.
Let's find out what exactly could have served as the root causes of the fact that the laptop began to make a lot of noise or overheated unjustifiably, and determine what measures can be taken to get rid of possible failures. As a rule, this does not apply to the new equipment just bought in the store, but rather concerns only those devices that have been in use for a long time. If you notice such phenomena immediately upon purchase, it seems that you are dealing with factory defects. However, if you buy a laptop with your hands, it is quite possible that the configuration was strengthened on it, and the cooling system simply can not cope with the functions assigned to it, which will be discussed separately.
Why the laptop is very noisy: possible reasons
As for the main causes of this phenomenon, for some reason many users usually attribute them exclusively to physical problems, often forgetting about the software impact on some of the “iron” components of a computer system. Among the most common reasons that the laptop began to make a lot of noise and overheat, most experts call the following:
- clogged device with dust and foreign debris;
- malfunction or incorrect setting of fans (coolers);
- reinforced configuration incompatible with the cooling system;
- constant use of high power consumption mode (high performance);
- possible problems with the hard drive and its components;
- incorrect operation of the optical drive or the presence of a disk in it;
- Software failures due to outdated device drivers
- viral effect.
Of course, this is far from all that could theoretically 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 effects of viruses on the system. The issue is debatable, and we will dwell on it separately. In the meantime, let's look at some of the simplest methods to fix 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 loud noise or overheating is connected precisely with the pollution of the laptop. This, incidentally, concerns not only the ingress of small particles of dust on the fan blades, but also its deposition on other components installed on the motherboard, as a result of which the cooling air stream simply does not reach them.
Thus, if you notice that the laptop is heating up and the cooling system is very noisy, which is usually accompanied by the release of hot air through the holes on the side walls where the coolers are located, the first thing is to disassemble the laptop (if this, of course, you probably know how it is make, or the laptop is not under warranty), and then thoroughly clean its “insides” from dirt and dust.
For disassembling the device, it is best to use special tool kits that can be purchased in specialized stores, and special vacuum cleaners, tampons, and wet wipes are suitable for cleaning.
Identify problems with the cooling system
Naturally, it very often happens that the laptop is very noisy only because the fans are not working in the normal mode, which causes overheating of the same processor or graphics accelerator. In this case, it is necessary to monitor the temperature.
Windows tools are not suitable for this, therefore it is best to use third-party utilities like AIDA64, HWMonitor and their analogues, which have software sensors for fixing the status parameters of a component of a computer device. Please note that in the normal mode, short-term achievement of the maximum temperature threshold is allowed, and each manufacturer of “iron” lays in its devices some “margin of safety”. 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.
Adjust cooler settings in primary input / output systems
So, you have determined that the laptop is noisy and very hot in excess of all permissible norms.
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, after which, if possible set other parameters or use automatic optimization. But many primary systems of such tools are deprived, so it is often recommended either to perform a full reset to the factory state, or to 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 start 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.
Fan speed adjustment in special programs
If the fan is very noisy on the laptop, but there are no settings in the primary system, you can use special programs. One of the most famous, powerful and popular is SpeedFan.
It is necessary to slightly reduce the rotation speed of the cooler, taking as a basis a step of about 5% or even less. Reduction should be made until extraneous noise in the idle mode, when no applications are running, disappear.
What to do when overheating is detected?
Often you can observe that the laptop is very noisy when playing games or when working with multimedia programs. In general, this is a normal phenomenon, since most modern software of this nature puts 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 not enough RAM. In this situation, the equipment simply can not cope with the processing of the increased volume of calculations. To fix the problem in the simplest case in the same games, you can take advantage of lowering the FPS level or screen resolution, disabling texture detail, etc. Of course, the picture quality will suffer a little from this, but noises with overheating will disappear, and the laptop itself will not fail prematurely.
Another situation is that the standard equipment was changed, and the cooling system was not designed for modernization.
In the example in the image above, the configuration of the DELL Latitude E6520 laptop, in which the factory kit includes only 4 GB of RAM, but it was increased to 8 GB by installing additional brackets. It is not surprising that the cooler on the laptop is very noisy just because it is not designed for such loads.
Power scheme change
Very often, game lovers for a more comfortable passage set a special high-performance mode, which can automatically provoke the appearance of increased load on system resources. This leads to the fact that the laptop is very noisy and heats up. In Windows 10, when you turn on game mode (Win + G), such a power scheme is automatically activated. To reduce the load a little, go to the power settings and set to balanced mode.
If this does not allow you to 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 is best to replace the processor, video card and RAM, naturally, without forgetting about the cooling system and the corresponding model of the power supply. As already clear, such a pleasure is not cheap. In addition, the new processor may not get up on the old motherboard, so you will have to change it, but in the end it turns out that it was cheaper to buy a new laptop.
Optical Drive Noise Reduction
It often happens that a laptop is very noisy only because there is a disk in the optical drive, when accessed, noise from its promotion appears. In addition, the disk may have scratches or physical damage, and therefore the promotion and attempt to read information are delayed for a very long period of time.
Troubleshoot hard drive issues
Finally, one of the most unpleasant situations can be called openings in the hard drive, which can be associated with the presence of errors on it, and with the fact that the hard drive starts to “crumble”, becoming unusable, and with incorrect power settings.
To identify possible failures and eliminate some problems, you can use the most common “Task Manager”, determine which process loads the hard drive the most, and then end the active service forcibly. It would also be nice to check the disk for errors using system utilities like HDDScan or quietHDD. However, if serious physical problems are identified, the hard drive is strongly recommended to be replaced. The best option would be to buy a modern SSD standard SSD. Such discs will definitely not make noise.
Hardware Driver Update
Software components in the form of device drivers can also cause such situations. This applies to video cards to a very high degree, if a discrete accelerator equipped with a powerful graphic processor and its own cooling system is installed on the laptop. And outdated or incorrectly installed control software can just cause malfunctions, in which noise and overheating may occur. Updating drivers using the operating system is not worth it.
It is better to use automated utilities like Driver Booster, which they find on the Internet, right on the manufacturer’s website, the necessary software, download it and install it without your participation.
Can side effects occur with viral exposure?
Unfortunately, it is impossible to exclude the presence of viruses in the system. Many people believe that virus threats cannot directly affect the hardware. This is not entirely true. Through the control drivers, any equipment can be disabled. In this regard, it’s enough to recall a virus that once “walked” on the Internet, which, when introduced into the 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 anti-virus, since it may not even detect certain types of threats. At least for prevention at least once a week, scan your laptop with third-party portable programs.
Epilogue
In conclusion, it is worth noting that this is not all possible situations in which the laptop is noisy or excessively heated. In fact, there can be many more, 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 grease on the processor or install another power supply, you can also upgrade the cooling system by purchasing a special cooling stand to reduce heat, etc. . In general, there are enough options.
