Typically, computers and laptops run almost silently. But sometimes the sound during operation becomes very noticeable and annoying. This indicates that the computer may have some kind of problem or it is working in an abnormal mode. How can you reduce the noise level of your computer? To understand this issue, it is necessary to find out exactly where the noise is emitted from.
Only moving parts can cause noise. It can be an active cooling system with fans, a hard drive - a hard disk drive. It usually works very quietly, but if its sound annoys you, then you can change it to solid-state SSD-drives. This will greatly increase the speed of the subdisk system.
If everything is in order with your hard drive, it means that the cooling fans are the source of the noise.
Ways to reduce noise from PC coolers
Computer fan noise can be eliminated in a number of ways:
- reduce the load on the processor;
- replace the cooling system;
- forcibly reduce the speed;
- replace small coolers with big ones;
- lubricate the fans;
- check the setting of the fans;
- clean the radiator from dust and dirt.
How to remove noise
The more the CPU is loaded, the more heat it generates and the stronger its fans work. And if the program also hangs on the computer, then the load will additionally increase. To fix the problem, it is enough to close the frozen program.
If you replace the cooling system with a liquid one, you can improve the heat dissipation. At the same time, during their operation, you will only hear the sound of a running pump and flowing water.
There are special programs to reduce the rotational speed of coolers. One of the most popular is SpeedFan. It is good in that it can control the speed of the fans in automatic mode.
The larger the fan impeller, the better the cooling effect it provides. At the same time, the number of its rotations is less, and, accordingly, the computer noise is reduced. Fan bearings are also different. Among the two types - rolling and sliding, it is better to choose the first option, since it is more stable in emitting sound effects.
Sometimes it is enough to just lubricate the fan to make it quieter. For these purposes, sewing machine oil is suitable. If you want to lubricate the CPU cooler, pry off the sticker that is glued to the bearing. Put some oil on it and stick it in place.
The fan setting is very easy to check. You need to enter the BIOS of your computer and check if the Smart Fun Control options are enabled in the PC Health Status section. Depending on the type of motherboard, the name of the function may vary. It must be enabled, that is, it must have the Enable status.
If a lot of dust has accumulated on the radiator, this disrupts the operation of the system, the fans have to work with a vengeance. To clean them, there are special cans of compressed air, which can be purchased at a specialized store.
Knowing ways to reduce the noise of your computer, you can easily cope with this problem. But if your device makes a sound that resembles a squeak or whistle, then your PC needs a replacement part. Monitor the health of your computer or laptop and fix problems in time.
