Today's question
Good day.
Tell me, I have a problem with a new laptop (it is 1 month old). At night I can clearly hear a slight hum when you start the game WOT (tanks) - the volume of the hum grows, and over time the laptop hums like a tractor! It bothers me very much, tk. it happens that loved ones are already asleep (and I get in the way ...).
Is it possible to somehow reduce the noise? Under the warranty, I can not hand over the laptop, more than 2 weeks have passed since the purchase of the device (it so happened that I did not check the device completely, because I was leaving).
Alexey, Moscow.
Hello.
Alexey, I want to say right away that there is no difference between noise and noise. Moreover, if there was no noise before, but now it has appeared, this may signal the appearance of hardware problems with the device.
In your case, most likely, when buying, you simply did not pay attention to the peculiarities of the laptop. However, there are still some things you can do. 👌
In this article, I will touch on the main reasons why a laptop can make noise, and what you can do about it ...

What can make noise in a laptop: eliminating the causes
I want to say right away that there are much fewer mechanical devices in a laptop than in a PC, from which there can be noise. On the one hand, this fact helps to quickly determine the source, on the other hand, due to the compactness of the device, it is not always easy to eliminate the cause ...
👉 Cooler
Probably the biggest source of noise found in most classic laptops.
As a rule, if you do not overload the device (i.e., do not run games on it, watch high-quality video, etc. tasks), then its operation is practically silent. Although some laptops do hear a little hum when approaching the side vents on the device.
👉 Hard disk
The most insidious source of noise. Firstly, some models can easily click and crackle during operation (some models do this under load). You can hear this noise only in complete silence (i.e. at night in silence 100% will be annoying).
Secondly, this is not a warranty case, and for this reason you will be refused to replace the device.
Also, under high load on the disk, a barely noticeable hum can be heard, similar to the noise of a cooler.
👉 CD / DVD drive
It emits a fairly strong noise during operation: there is both a rumble from the rotation of the disk, and light crackles. By the way, many users forget to simply remove the discs from it, and because of this, the laptop often spins the disc in the tray and a noise appears.

Reason # 1: the cooling system is clogged (if the cooler rumbles)
Perhaps the main reason why the cooler starts to hum (or, as many say, "rattle") is a large accumulation of dust that closes the ventilation holes, accumulates on the impeller and interferes with normal air circulation.
Due to dust, the cooling system cannot cope with the load, the cooler starts to work faster, and as a result, the noise increases.
The difficulty of cleaning a laptop from dust depends on its configuration. Some laptops will not be difficult to clean on their own, even for a completely novice user, while others - to get to the cooler, you will need to completely disassemble the entire device!
Therefore, see here for yourself: either to the service, or an attempt to try to do everything on your own. I gave my thoughts and recommendations on how to do this in one of the articles (link below 👇).

Details on how to clean a laptop from dust on your own
At all, 1-2 times a year it is highly advisable to clean the device and remove excess dust. It will not be superfluous to lubricate the cooler during this procedure.
If the impeller makes a noise, periodically touching the case (for example, it can be damaged by careless cleaning), then it is easier to replace the cooler completely.

Reason # 2: high temperature and load on the laptop
Perhaps this reason partly overlaps with the first. The thing is, the laptop cooler is working dynamically - i.e. rotates at different times with different speeds.
The higher the processor temperature rises and the higher the load on it, the faster the cooler starts to rotate in order to cool more and have time to remove heat. And such a cooler operation, in turn, leads to the appearance of hum and noise from the laptop ...
By the way, during this hum, when the cooler is working at its limit, hot air usually starts to come out of the laptop vents on the side. The keyboard can also become warm, and it can become uncomfortable to work (especially Acer notebooks with AMD processors are a sinner of this).
And so, how to find out the temperature of the processor, video card in a laptop?
The easiest way is to use the special AIDA64 utility (link to the collection of utilities). To view the temperature of all components in AIDA64 (CPU, video card, hard drive, etc.) - go to the tab "Computer / Sensors" .

The best utilities for viewing the characteristics of your computer (including AIDA64).
The screenshot shows the temperature: CPU (48 ° C), Video cards (43 ° C), Hard disk (35 ° C).
👉 By the way!
I told in this article my humble opinion about what temperature I consider normal, and at what temperature I need to do something.
To lower the temperature, I recommend the following:
- use laptop only on level, dry, hard and clean surfaces (otherwise many people use a laptop lying on the couch - and because of this, the ventilation holes may be blocked, which leads to overheating);
- regularly (1-2 times a year) carry out 👉 cleaning the device from dust;
- if you like to play games, and also indulge in heavy applications: video and graphic editors, etc. - purchase for a laptop cooling pad... It is a way to lower the temperature by 5-10 degrees (though note that some of them make noise ✌);
- see if the high CPU load is related to something else, not just the running game (I recommend that you read this article: //ocomp.info/protsessor-zagruzhen-na-100-i-tormozit.html);
- can also be manually configured rotational speed cooler (carefully! do it step by step, take your time and monitor the temperature) - //ocomp.info/kak-nastroit-skorost-kulera.html
- it is possible to disable Turbo Boost and carry out Undervolting. This allows reduce CPU temperature by 10-20 ° C... How to do it here: //ocomp.info/snizit-t-cpu-tonkie-nastroiki.html
- if it is very hot outside your window - try not to use your laptop in the sun, if possible, load it in the morning, evening hours, when the temperature gets lower.

Reason # 3: hum, crackles and clicks from the hard drive
Some models of hard drives emit mechanical noise during their operation: crackling and clicking sounds. If the room is very quiet, then these clicks are very annoying. This happens due to the rapid movement of the block with magnetic heads. Looking ahead, I will say that the speed of movement can be reduced, thereby reducing the noise ...
How to reduce disk noise:
- replace the disk with another one (which does not make noise). Best option: install SSD-disk (you can buy them on the cheap here) - it is a priori silent, tk. it has no mechanics, and besides, such discs are much faster! Comparison between SSD and classic HDD, presented in this article: //ocomp.info/kak-proverit-skorost-diska-ssd-hdd.html
- check in task manager (to call it - press the combination Ctrl + Alt + Del) - is there any application that heavily loads your disk (most often these are torrents, p2p programs for downloading files);
- reduce the speed of head positioning using utilities quietHDD andHDDScan... How to do this, see this article - //ocomp.info/pochemu-shumit-i-treshhit-hdd.html
- if your hard drive did not make noise before, but now it has started - this is an alarming symptom, I recommend checking the HDD for errors and bad blocks.

Reason # 4: forgot to remove the CD / DVD disc from the drive
Many classic computers and laptops have a CD / DVD drive (although some new ones do not install it at all). Becausethis is a mechanical device (like an HDD) - then when the disk is spinning up (especially at maximum speeds), it starts to hum a lot. The noise from it is stronger than from an actively working cooler.
If you forget to remove the disc from it, then every time you open the explorer (folder), the drive will spin up the disc, trying to provide you with information. As a result, noise will appear, and for 1-2 sec. the computer will freeze ...
Here's what you can do and the reasons why your CD / DVD-ROM drive is making noise:
- check if there are scratches, chips on the media (disc), is it even? Warped discs make much louder noise;
- you can try to install specials. utilities that can limit the speed of rotation of the disk, for example,Nero Drive Speed;
- try to insert different discs: CD-R, CD-RW, DVD-R, etc. I also recommend trying to use licensed discs of a well-known brand, and not purchased in the passage at an unknown counter;
- if there is a label on the disc, then perhaps the reason is in it, it may be applied unevenly (some thick labels can also affect the noise level of the drive);
- noise in the drive may appear due to foreign objects, for example, a piece of a chipped disc (did you have one, did anything get into the drive?).

Reason number 5: not optimal performance of BIOS and drivers
Many people underestimate the performance of BIOS and drivers, however, they can have a big impact on the performance of a laptop. As for the noise, as you've probably already noticed, the cooler in the device works dynamically, i.e. the higher the load and temperature, the faster it spins. This mode is enabled by default in the laptop BIOS (sometimes it can be configured, sometimes not). It is usually called like this: Q-Fan, CPU Fan Control, Fan Monitor, Fan Optimize, etc.
In some BIOS versions, this cooler adjustment mode works "very badly" - ie. the cooler works much faster than it is required from it at a given time. As a result, there is constant noise and hum from it (regardless of the load).
There are a couple of ways out: try 👉 update the BIOS (be careful! When updating - you can easily spoil the device's performance) to a newer version (if available on the manufacturer's website).
👉 To help!
I also recommend checking and updating the drivers. The best programs for automatic search, download and installation of drivers are presented here
The second way out: turn off the automatic mode in the BIOS and configure the cooler yourself using a special. utilities. You can see an example of how this is done in this article: //ocomp.info/kak-nastroit-skorost-kulera.html

I hope my humble advice helped to get rid of the "loud" noise and calm the nerves 👌.
For additions to the article - a separate merci.
That's it, good luck!
