Noise from the system unit is always a bad sign of a computer's performance. You should get rid of it not only because it irritates our ears, but it can also affect computer performance and wear and tear on parts.

Avoid overloading your device

Usually, computer noise increases during the launch of games or other programs that require high computational power. The loading of components raises their temperature, automatically increasing fan speed and, consequently, creating additional noise.

This process is entirely normal. Lowering the fan speed in system settings may be an option, but it could potentially lead to device overheating. Therefore, if the computer is free of dust and the noise increases only during resource-intensive tasks, it might be better not to intervene in this process.

At the same time, it is advisable to avoid prolonged gaming sessions if the computer heats up significantly. Regular breaks will allow it to cool down.

Place system unit on level surface

If your computer emits a noise resembling vibration, check whether the system unit is in a stable position and not wobbling. Ensure all rubber feet are in place, and if any are missing, replace them.

Check assembly quality

Sometimes, noise may be due to inadequate fixation of case elements or internal components to each other. In this case, the rotation of fans and disks can cause rattling, resulting in an unpleasant vibrating or rattling sound.

To address this issue, disconnect the power and other cables from the computer, then remove the side cover by unscrewing two or three screws from the back panel. Carefully inspect the internals of the system unit and ensure the necessary fastening is present and secure. If bolts are missing, find and install them, tightening the ones already in place.

Also, pay attention to ensure that fan blades do not touch any wires, as this could cause friction noise. Secure all cables using ties.

Remove dust

If your computer has started making noise recently, even during non-resource-intensive tasks, the issue might be dust accumulation. It builds up on the fan blades, causing additional friction and hindering the normal operation of the fan. This results in a distinctive humming sound.

Moreover, a layer of dust on the PC's heat-producing components interferes with their cooling, raising the overall temperature inside the case. The fan starts spinning faster and, consequently, generates more noise.

Warning! Incorrect disassembly and cleaning may damage the computer. If you are unsure of your capabilities, do not take the risk. And remember: opening the case will void the warranty.

To reduce noise levels, you'll need to remove the dust. It's best to do this on a balcony. Using a dry, soft brush, gently brush the dust from all internal components, including radiators and fans. Then blow it away with compressed air or very carefully vacuum it. When blowing, it's advisable to hold the fans with your hand, preventing them from spinning.

Lubricate fans

Even after preventive cleaning, coolers can sometimes make a noise that is often caused by a lack of lubrication or wear and tear. Instead of immediately replacing the components with new ones, it makes sense to try lubricating the fans first. It is recommended to repeat this procedure about once a year.

First, disconnect the cooler cable from the motherboard or power supply. Use a screwdriver to unscrew the mounting screws and remove the fan. Turn it over so that the impeller is facing down, and then carefully remove the round sticker. There may be a rubber seal underneath, which should also be removed using a needle.

Inspect the recess with the fan shaft and the locking ring. Check if there's any lubrication. If the recess is completely dry, the fan clearly needs lubrication. Take machine oil or universal lubricant for household use and apply three to four drops to the shaft. Rotate the blades several times along the axis to evenly distribute the lubricant inside the bearing.

Place the rubber gasket back in its place (if there was one), and degrease the plastic around it with alcohol. Let the fan dry, then reattach the sticker. If it doesn't hold, you can replace it with a piece of reliable tape. Install the fan back in place and reconnect it.

Replace hard drive

Another source of computer noise can be the hard drive. Sometimes, this device can produce noises like clicks or other sounds, indicating problems with its operation and signaling its imminent failure. To get rid of these sounds, the only solution is to replace the hard drive. Opting for a silent and fast SSD is the optimal choice.
