If the internal heat dissipation of the power supply, the internal temperature is too high, it is easy to lead to the internal capacitor bulge, enter the power supply instability, resulting in computer crashes, blue screen and other failures occur, and may even burn the power circuit to cause the necessary losses. Therefore, I would like to buy a power supply, the best choice of moderate price, brand better power products, because this kind of products in the materials generally do not have Jerry, for the stable operation of the computer plays a very important role.
If the power supply fan is larger than the power supply caused by long-term use, we can remove the power supply from the chassis, and then open the power shell, the opposite for a certain clean, with a brush to clean the more dusty power fan, generally this can be to some extent to solve the power supply fan noise problems, it is important to note that, If the power supply is still under warranty, it is recommended to take the warranty, or with a hairdryer to the fan mouth from the inside out to blow.
Generally speaking, the power supply fan sound is mainly due to poor quality of the power supply fan or fan accumulation of a large number of dust. The quality of the power supply fan is mainly the power supply manufacturers choose a relatively low price of the cooling fan, in some low-cost cottage power, poor quality of the cooling fan used a lot.
