The cooling system is considered one of the main parts of the computer, as it, while maintaining the operating temperature in the system, ensures the stable operation of all components. Sometimes it happens that over time the cooler starts to make noise. Further you can learn how to reduce fan noise.
CPU fan noise reduction
A processor is the brain of a computer, without which no system will function. Since it does not have its own cooling source, it is mounted separately. Over time, the cooler starts to make noise during operation, and now the best option will be presented to solve such a problem as reducing the fan noise in the computer.
To make sure that the processor cooler is noisy, you need to turn off the power of the processor cooling system for 5-10 seconds during an idle start. This time will be enough to make sure that the fan in the computer is noisy from the processor.
It is also not difficult to check the overheating of the processor itself, since for this you will also need to disconnect the cooler power from the motherboard. If after 10-15 seconds the radiator has become much hotter, then the fan speed should not be reset.
To cope with a task such as reducing fan noise in a computer, an ordinary awl will help. Then you need to pick up the power plug, which connects to the motherboard and deploy the contacts facing you.
With an awl, slightly press the central contact and pull out the red wire. After that, the plug is sent back to the power connector, and the red wire remains idle so far.
The next step in solving the problem of how to reduce the fan noise in the computer is to connect the red wire to a free plug coming from the power supply. Here you need to be extremely careful, since the red wire is connected exclusively to a contact of the same color.
Fan noise reduction principle
In this case, the voltage is taken into account, since the pinout indicates that the red contact carries a voltage of five volts. Accordingly, if you lower the supplied voltage to the cooler cooling system, then its speed will significantly decrease, which will lead to a decrease in outgoing noise.
Eliminate fan noise in the power supply
Now that you know how to reduce the noise of a fan in a computer on a processor, you can make out the situation with the power supply. The power supply maintains the health of the entire system by supplying electric current through the power cables. But, like all the important parts of the system, it needs decent cooling. Radiators and a cooler do well with this, but over time the cooler starts to make noise, which can interfere or even annoy. First, you need to figure out why the fan in the computer is buzzing in the power supply and how to deal with it.
If the fan in the power supply unit starts to make a crack, it means that it must be disassembled and greased. Lubrication for the cooler is necessary in order to silently rotate the fan blades, cooling the entire unit.
Practical part
After disconnecting the power supply from the mains, you must wait 10-15 minutes to allow the capacitors to completely discharge. The cooler rests on four bolts that need to be unscrewed. Next, you need to unfasten the sticker, which is located on the front side of the cooler, since its absence will facilitate access to the place of lubrication.
There is a special plug under the sticker, which also needs to be disposed of. Under the plug is the impeller lock, which prevents the fan from hanging around the casing. The plug, which looks like a ring, has a small slot across the axis. Spreading the slot, you can pull out the ring.
After all the manipulations, you can pull out the impeller and clean it from dust. The other part of the cooler needs to be lubricated with a lubricant for the cooler, which is called MS-20. You need to lubricate the fan shaft and the sleeve inside the cooler. After that, you can start the assembly.
How to get rid of dust in the system unit
A dusty system unit is a bad sign, followed by overheating of some components of the computer and a decrease in their performance. Therefore, it is worth at least once a year to give the system unit to a computer center for cleaning or do it yourself, saving a lot of money.
System block parsing
In order to understand how to clean the computer from dust, it is necessary to prepare a workplace on which there should not be anything superfluous. You can arrange several boxes next to them to put bolts and screws, as well as other small parts.
Other accessories are also needed if you need to clean your computer from dust. This list includes: cross and flat screwdrivers, alcohol wipes, thermal grease, awl.
Then the computer is disconnected from the network, and the system unit is disconnected from the entire periphery. After that, you need to get rid of the side panels by unscrewing all the fixing bolts, and then put them in a separate box. Then you can proceed to disconnect all the components that are located on the motherboard.
The next step is to wipe the dust from the spare parts with a dry rag that does not contain lint, since its presence can adversely affect the operation of components. Water should not be used.
Motherboard cleaning
After the motherboard has been disconnected from the case, it is worth considering its degree of dust. If dust has accumulated in places where a finger cannot be reached, then it is worth using cotton wool and an awl. However, cotton wool fibers can remain on the legs of the chips, so you should carefully monitor your work.
Next, you need to wipe the RAM strips and remove the cooler from the processor. Dry cooler must be removed from the cooler and a new one applied. Alcohol wipes are well suited for these manipulations. It’s also worth removing the old paste from the processor.
Fan cleaning
Cleaning the cooling fans in the computer is the most important step, as these coolers are responsible for the overall cooling of the entire system.
Conventional cooling coolers do not need to be disassembled, so just wipe them with a damp cloth. As for the coolers located on the processor and the video card, then it is worth disassembling them, since such active cooling needs more careful care.
To disassemble the video card and the processor cooler, you need a suitable size screwdriver. When removing fasteners from a video card, you need to be careful, as there is a chance to damage the printed circuit board. After that, you need to wipe the fans and the radiator, and then assemble everything back.
The cooler is also not difficult to disassemble, having unscrewed several bolts, you can wipe the fan blades, the radiator and put everything in place.
