Turn off the power supply of the radiator. Rear reinstallation system. There is a problem with your power supply. Or unpack the dust.

The solution to the problem that the fan is still running after the computer is turned off is as follows:

1. First of all, click the start icon on the desktop, and click Run in the pop-up start menu

2. Then, enter "OK:" in the input box

3. Then, click "Manage Module" in the left interface of the pop-up window

4. Then, click on System Folder in its drop-down menu:

5. After that, pull down on the right side and find "Windows system shutdown does not power off after it happens":

The computer is turned on, and the power fan turns and does not respond, which may be due to the following reasons.

1. First of all, it can be a switch problem, such as a bad contact. We turn off the switch on the back of the computer, or simply unplug it. etc. will be reinserted.

2. If it doesn't work, it may be that the computer has static electricity, causing adverse reactions. We can find a piece of gold head and a piece of wire to help the computer screw, and connect the other end to the metal that is in contact with the ground at home. It is better to buy steel wire to be beautiful.

3. It is also possible that the memory module is in poor contact, which is quite possible. Remove it and wipe it clean with an eraser. Then plug it back in, to be steady. Dual memory note compatible.

4. Computer fan problems. Fan problems will cause the system to determine that there is no fan, and in order to protect the computer motherboard, the computer will be forcibly stopped. Solution: Check whether the fan is in good contact. Reinstall. It's best to add some heat sink.

5. Graphics card problems. It's also quite possible. Most of them are poor contact. Simply remove it and reinstall it. The screws should be tightened. The installation should be stable and slow.

6. Motherboard problems, if it's okay. That could be the motherboard. If this is the problem, then you can only go to the repair shop to check if there are any problems such as bad sectors.

The main performance of the fan is reflected in the following aspects: speed, fan blade shape, fan blade, and CPU fan.

1. Angle and bearing system. In general, the speed of the fan is indicated on the manual of the radiator. Generally speaking, 30% of the heat dissipation effect of a radiator depends on the speed of the fan.

But the higher the fan speed, the better. The correct fan speed should be determined according to the heat generated by the CPU, and the fan speed selection of different specifications should be differentiated.

The basic principle is: under the premise of generating the same air volume, the larger the fan, the lower the speed, and the noise will also be smaller, generally between 3500 rpm and 5200 rpm is more conventional.

2. The greater the power, the stronger the fan wind, and the better the heat dissipation effect. The power of the fan is directly related to the speed of the fan, that is to say, the higher the speed of the fan, the more powerful the fan. At present, the best fans in the general computer market are DC 12V, and the power varies from W to W, so the power needs to be selected according to the heat generated by your CPU.

3. A better radiator, there will be no burrs on the edge, no deformation of the heat dissipation fins, smooth bottom without cracks, neat appearance, generous shape, quality assurance, anti-counterfeiting marks or other characteristic trademarks, etc. In addition, when choosing a radiator, you should also pay attention to the bottom of the radiator should not be too thick, because the thermal conductivity of aluminum is not very good, and too thick will affect the transfer of heat;

In addition, the deflector groove on the surface of the radiator should be denser, which can ensure that the radiator can have a large contact area with the air, so as to enhance the heat dissipation effect. Generally, computer enthusiasts will give the CPU ** water cooling fan to achieve rapid cooling effect through the circulation of liquid.

When the power supply is turned on, the current is output and the fan is activated.
