usually installed in the system unit a few fans: on the radiator of the processor, the graphics card (in the presence of an active cooling system), to blow hard drive for ventilation casing in the power supply.

energonagruzhennymi most PC components are the CPU and graphics card.Accordingly, they have the most powerful cooling systems, which are the main sources of noise.On the other hand, since all modern processors, including graphics, equipped with energy-saving features at small loads of the thermal dissipation power is low.The fan or turbine installed on their cooling systems virtually no noise issue as the number of revolutions of these devices is determined by the temperature regime.The same applies to the power su
pply - the work of his fan is usually heard only at a significant level of power consumption of components installed in the system unit.

To reduce the overall background noise, all other fan if necessary, can be replaced by a low-speed, with a speed of 1000 rev / min.If your motherboard supports fan voltage control, they must be powered from the corresponding connectors.Many manufacturers equip their models with special shock absorbers, extinguishing the transmission of vibrations from the fan to the body.If necessary, they can also be purchased separately.

One of the most difficult avoidable sources of occurrence of noise is the hard drive.As you know, the hard drive is equipped with a drive spindle and the drive of the magnetic heads.This spindle speed is constant.When properly installed, the drive for quality housing, the noise of the disk rotation is almost imperceptible, except for the time of launch.But the sounds that occur when you move the magnetic heads, particularly under intensive search operations, some models of hard disks can be quite loud.

Fortunately, almost all hard drive manufacturers equip their device management function of acoustic noise level (Advanced Acoustic Management) or abbreviated AAM.Its essence lies in the fact that by changing the electrical parameters of motor control can reduce the acceleration when moving the magnetic heads of the drive.This entails a reduction of the noise produced at the same time.This operation is not recommended for system drives, as this increases the value of the access time of the hard drive, which can slow down its speed.

manage noise levels allow nearly all utilities for working with hard drives.In Windows you can do this using the free 15-day version of HD Tune Pro.This tool will not only change the AAM, but also a comprehensive assessment of how and how much has changed with the speed of your hard drive when performing common operations.

If this method significantly improve the noise performance of the installed hard disk did not work, or it is for some reason unacceptable, you must purchase a special box for the hard drive, such as a model HC01-TC is powered by Arctic Cooling.The accumulator located in the vibration damping device racks, cooling is carried out by means of a small fan, which turns automatically depending on the temperature inside the box.

These methods can reduce the noise of the system unit home computer at a low load to a comfortable level.

As a result, if your computer is very noisy, maybe you need to check the temperature of all the components and, if necessary, to clean the cooling system or replace the thermal paste on hot items
