Why should the power supply of the computer have a fan?

Wrong, the role of the power supply is actually a regulated power supply, which is still a transformer, after 220V goes in, it is divided into 3V 6V 12V 36V and so on, so it has to generate a lot of heat in this process. It's just that there is a fan, you can't feel it, especially in winter, if it's in the summer, if the fan doesn't turn, it won't take a lot of time to burn out. It can be seen that the role of the fan is not ordinary.

...This question is as simple as why people want to eat, the heat of the power supply is not felt when you turn on the fan, you can try to stop the fan and then use it for 1 hour to feel the power supply, especially in the last summer, you will understand why the fan!

Then you will dismantle and sell your scrap metal quilt. A dot internet fee is out!

In summer, the temperature is too high, and the heat inside cannot be discharged, and the lumps are easy to burn.

I even have a fan on my computer.

The power supply fan is used to dissipate heat, so that the power supply can work stably, even if your computer is not turned off for a few days, it will not be affected by the high temperature of the power supply.

The fan power supply is generally provided by the internal power supply and the fan power connector of the motherboard.

1. Whether there is a fan power supply or not.

2. That is, 0 decibel power supply, such as: Great Wall brand.

Haven't seen one without a fan, without a fan your power supply will burn out quickly.

Yes, but because the demand is small, there are few ones on the market, you can go to the counter that sells power supplies to understand, and you generally need to place an order.

In addition, ** is in large quantities, and it looks like this.

The difference between dynamic heat dissipation.

Fanless power supplies are available, but they are not available and are rare.

The CPU heatsink doesn't need a fan, just wait to burn.

The simple meaning is that the function of the power supply is to convert the mains 220V AC power into DC power to supply power to the motherboard, hard disk, optical drive and other equipment in the host, the conversion efficiency of the switching power supply is about 70%, and the other 30% is converted into heat energy, so it is necessary to add a fan to dissipate heat.

And if you look through the gap in the power supply shell, the switch tube and rectifier tube inside are installed on a large white heat sink, so the power supply heat dissipation is also very important.

As for which temperature is high, I haven't tried to remove the power supply fan for how many days, but when repairing the power supply, the fan is removed, and when repairing the motherboard, it is necessary to put on the CPU fan, otherwise the temperature will be too high for protection after 2 minutes of booting, and it will be hot to touch your hands. Needless to say, the CPU temperature is high.

The computer power supply dominates the total power work of the whole set of equipment, there are capacitors and transformers in the power supply, your external power supply is generally 220V, it is not in the computer, this is by the power supply inside to transform the voltage, while working, it will emit a lot of heat, if you do not install a fan to blow and blow, reduce the temperature, it is easy to burn out the power supply.

There could be two reasons:

1.If the fan is aging, either add some oil or change it.

2.If you think that your fan has not been used for a long time, see if it is because the room temperature is relatively low, because the temperature is low, the oil on the fan bearing becomes very sticky, and the lubrication effect is not good, so when you turn on the machine for the first time (especially in the morning), the sound is relatively loud, but if you use it or restart it, it will be gone. Normally, this problem does not occur in the summer.

It should be able to be opened, otherwise how to fit it in

It can be disassembled, after dismantling, use a needle (syringe in the hospital) to suck a little sewing machine oil, if not, use cooking oil, tear the fan label, inject a few drops of oil, and then seal it with tape, the noise will be reduced, this is only a temporary solution, and when the oil is dry, there will be the current situation, if it is convenient, just change to a fan of the same size, the same voltage, and the same current.

Generally, the fan can be changed, but after turning on the power supply, it is directly on the motherboard, if the hands-on ability is strong, you can weld him down with electrochrome from the power supply motherboard and then replace it, if the hands-on ability is poor, just cut the money directly, and then pick it up, be careful not to connect it in reverse, otherwise the fan will be reversed, the fan, it used to be bearing, and it is OK to change a ball, with a long life, small sound, and cool Supreme

The main function of the power supply's fan is to dissipate heat while being silent.

1. The ball fan does not use oil, has a long life, high friction, and has an impact on the speed.

2. The oil-containing fan is low, but there will be noise after the oil dries, and the speed will also decrease;

3. The hydraulic fan is also an oil-containing fan, but there is no oil cap, and the motor is sealed through one-piece molding, so there will be no oil leakage and no oil drying;

4. The nano fan makes the motor rotor and stator more concentric and more accurate, less friction and longer life through a more precise nano process. Nano fans are also a type of hydraulic fan, which is quieter and has a longer lifespan.

At present, Xinmai power supply is the fourth kind of fan used.

Hello, in general, no interface can not be used, that is to say, your device cannot be installed, unless the motherboard is replaced.

It's not enough to buy an adapter cable, there are many places to sell it.
