The computer fan spins as soon as the web page is opened (the computer fan spins as soon as the computer is turned on)

The computer fan spins at high speed after turning on the computer, making bursts of noise, which is unbearable. This problem troubles many users and affects their experience. In order to help everyone solve this problem, PHP editor Banana has collected relevant information for everyone and compiled the following solutions. Please read it carefully and find a method that suits you so that the computer fan no longer makes noisy noise.

1. The computer fan spins as soon as it is turned on

The computer cannot be turned on, and the fan spins and then stops. Possible reasons: Solution: Turn off the power immediately, carefully check and eliminate various faults, restore the motherboard to factory settings, and remove it For all boards and peripherals (hard disk, optical drive, etc.), go to the minimum system to see if they can reliably boot into the motherboard Bios interface. What are the reasons why the computer fan is too loud:

1. The notebook itself has hardware protection measures. When the system temperature reaches a certain height, especially the CPU temperature is high, the notebook will increase the speed of the exhaust fan and start to dissipate a lot of heat. , the exhaust fan of some notebooks will not rotate when the workload is low, and the exhaust fan will only be started when the system temperature is too high. In this case, it is beneficial to the stability and safety of the machine, so it is not within the scope of the discussion. .

2. To refuel the exhaust fan, buy a bottle of sewing machine oil. If you have peanut oil at home, you can also use this instead. Add oil to the exhaust fan shaft and the groove close to the coil. After oiling, let it soak for a while and then install it. This is basically This will solve the problem of loud sound.

3. The position of the exhaust fan is offset due to excessive dust accumulation or loose fixing screws. The solution is: clean the dust and re-fix the screws.

2. What should I do if the computer fan starts spinning as soon as I turn on the computer? There should be something wrong with the BIOS. Restart and press the del key (speeds 9000 mkp) to enter the BIOS. If it is in Chinese, check the fan control. If it is in English, look for the cpu fan. With case fun, the post-adjustment speed is usually rpm or something, and around 1000 is a relatively balanced speed.

3. Why does the computer fan spin when I turn it on

The reason may be that the engine water temperature sensor is damaged or the car's fan control system is faulty.

Solution: The engine water temperature sensor is damaged: You need to check whether the temperature signal sent by the water temperature sensor to the engine computer is abnormal. At the same time, you can determine the problem with the water temperature sensor by reading the engine fault code.

If there is no problem with the water temperature sensor, you should check the engine computer. Car fan control system failure:

4. The computer fan keeps spinning as soon as it is turned on

1. It is recommended that you try to set it in the bios: keep clicking F10 to enter the bios after turning on the computer, select System Configuration, change the fanalwayson option to disable, and then Click F10 to save and exit to try. 2. If the fan rotates for a long time, it means that the heat dissipation demand is relatively large at this time. It is recommended to refer to the following solutions: 1. Heat dissipation: Due to the mechanical movement of the internal hardware of the notebook when it is working, some heat will be generated; and the notebook is a highly integrated computer. Portable electronic products have small internal space and poor heat dissipation compared to desktop computers. You can try adding a cooling base or raising the bottom of the notebook to see if it improves. 2. Software: It is recommended to turn off startup items and virus scanning to prevent excessive usage of system CPU system resources and generate a lot of heat. a. You can upgrade the machine’s anti-virus software for full anti-virus. b. Turn off infrequently used startup items. The method is as follows: Press the Win+R key combination to call the run window, enter msconfig, click OK, select the "Startup" selection card, cancel the startup loader that is not required, and then OK to close This program starts at boot. 3. Hardware: After the machine is used for a period of time, lint and dust will accumulate on the vents and fans of the machine, hindering air circulation and causing the temperature to continue to increase. It is recommended to contact the maintenance center for inspection or dust cleaning.

5. Turn on the computer and turn the fan on

You can use the following methods to know what the problem is:

　1. Observation method, see if the power light of the host is normal. If it can display normally, you can rule out the power supply problem, otherwise change the power supply (or Check the power line socket, etc.).

　2. Listen to the sound, and you can judge it based on the BIOS power-on self-test alarm sound. If there is no alarm sound, you can determine two reasons (motherboard failure or graphics card failure or other card failure). You can try the third method.

　3. Plug and unplug method, unplug the CPU, memory, graphics card, etc., including other plug-in cards (it is best to use a brush to sweep away the dust, be careful not to get water), and use an eraser to remove the golden fingers of the memory or graphics card. Wipe it once, then plug it back in or change the socket. When wiping the memory, insert it quickly from both sides at the same time. Don't push it in slowly at the same time

6. Does the computer fan spin when it is turned on

It will spin as soon as it is turned on. It's just that when the speed is low and there is no sound, you can't notice it. When there are requirements for heat dissipation, it will automatically increase the speed and make noise, and you will notice it at this time.

7. Why does the fan keep spinning as soon as the computer is turned on

This situation is caused by the internal hardware not being cleaned for a long time, or the memory module is not installed properly, or there is a problem with the connection between the CPU and the heat dissipation silicone. The specific solutions are as follows:

1. Unplug the power supply and prepare cleaning tools; use a screwdriver to open the case and clean the fan; it is easier to clean the fan by pulling it up, and install it after cleaning. restart.

2. Pull out the memory stick, check it with an eraser, and then put it back into the computer. Be sure to fasten it tightly when installing. Normally, if the memory stick is not placed properly, the computer will turn on without any response and only the fan will move.

3. Replace the computer cooling silica gel. Prepare the silica gel. Buy it once and it is enough. Unscrew the screws around the computer fan. You will see that the CPU and the cooling silica gel are sticky. Wipe it off with paper and replace it with a new one.

8. Is it normal for the computer fan to start spinning as soon as it is turned on?

The power supply is aging and damaged, which often causes the fan to stop spinning once. Replacing the power supply can solve the problem. The power switch is damaged. This is not common. Unplug the cable that connects the power switch to the positive and negative poles of the motherboard switch, and use a screwdriver to short-circuit the positive and negative poles. If the computer can light up, the switch is undoubtedly damaged.

When upgrading the memory, be sure to unplug the power cord, and it is best to touch the radiator or the like to discharge your own static electricity.

9. The fan keeps running when the computer is turned on

Running the CPU fan at full speed will not do any harm to the computer, but you must check the reason why the fan is running at full speed. The CPU fan should not be running at full speed for no reason unless it is running There is a problem with a large program or the computer's cooling system, such as excessive dust or poor heat dissipation contact due to a lack of thermal grease. This will accelerate the aging of the computer, but it is not caused by the fan running at full speed.

10. Turn on the computer fan and turn it on

1.

Re-unplug the power cord (both ends) and test whether the fault disappears.

2.

Confirm whether the user has installed and disassembled the components inside the host, whether there are foreign objects inside the chassis, and restore the components inside the host before testing.

3.

Reinstall the host power supply. (Connection end of power supply and motherboard)

4.

Whether the motherboard CPU fan is installed in place (some machines cannot be turned on without the fan installed).
