PC hums - it may be because of it

If your PC is humming, there can be several reasons. It is either due to electronic components or the way in which they are installed. We'll explain what you can do about the hum.

PC hums: That's why there are whirring noises

• In the power supply of each computer there are coils made of copper wire, which transforms the mains voltage down to values ​​customary for the PC.
• If these coils are not dimensioned appropriately, they start to vibrate mechanically under certain load conditions.
• The problem then manifests itself for you as a high-pitched whistle or as a hum. In the case of high-quality power supplies, the coils are also covered. This means that the coils can no longer vibrate and no longer emit any tones.
• If it bothers you very much, you will have to replace your power supply completely. The hum is harmless with most power supplies, but sometimes it can also indicate a defect in the power supply.

Vibrating hard disk as noise

• Your hard drives can also be to blame for the hum.
• Conventional hard drives, unlike SSDs, vibrate while they are in operation.
• If you're unlucky, your hard drive will often vibrate at a frequency that is very close to the natural frequency of your case. This creates a humming and vibrating.
• This phenomenon can also occur if several hard disks are installed one above the other.
• You can get rid of the annoying noise by decoupling your hard drives. Decoupling kits are cheaply available in many versions on the Internet.
