Cooling the power supply is an important function. If the computer is overheated, stable operation is impossible. There is a possibility of a sudden shutdown and loss of necessary data. To prevent such situations, it is necessary to carefully monitor the operation of the cooling system fan and eliminate the causes of failures in time. For quality service, you can contact the service center, where only a qualified specialist can give a guarantee for their services.
The fan in the computer power supply is used to cool the system, prevent overheating of its components and possible failure of the computer. Each part has its own resource, i.e. its service life, and over time, when you turn on the personal computer, you can hear only silence. This means that the fan has stopped spinning. This can happen for a number of reasons.
The main types of breakdowns of the cooling fan of the power supply include: pollution, foreign matter, grease, mechanical failure, power supply wire.
Pollution
The most common reason for a fan to stop is mechanical contamination. Air is constantly blown into the system unit, and the dust contained in it, over time, settles on the elements of the fan.
The system unit includes all the main devices for receiving, transmitting, processing and storing information.
Eventually, there is so much of it that it interferes with the rotation of the blades. The easiest way to remove dust is to vacuum by placing the vacuum cleaner tube over the air intake. However, this cleaning will not help for long. It is more correct to disassemble the computer and clean the blades and other elements of the fan, mechanically removing dirt.
Foreign object
Despite the obstructing filters, small objects such as a paper clip, parts of a broken pen, coins, screws can get into the air intake hole. The reason can be found out and eliminated only by disassembling the system unit. In addition to simply stopping the fan, a foreign object can lead to its breakdown, which is the next reason for a failure in operation.
Grease
The fan, like any mechanism, needs lubrication. It needs to be updated over time. Bearings overheat without lubrication and do not provide sufficient rotation speed. The prevention is the application of lubricant to the fan mechanisms.
Synthetic machine oil is used as a lubricant for fan slide bearings.
Mechanical breakdown
Mechanical damage can occur due to the ingress of a foreign object or if the fan is of poor quality or old and has worn out. Any material has its own service life and changes shape or breaks under dynamic loads. Therefore, over time, any fan may crack or bend the blades. In this case, only replacement will help.
Power supply wire
Often, when moving the computer due to a shake or when disassembling the system unit on your own, the wire supplying the fan can come off the connector. As a result, it stops working from a lack of electricity. In this case, a visual check of the fan wires will help.
