Fan problem with the new computer, is it normal for the fan to ring on the new computer

Poisoned, this situation is generally a worm, the boot speed is okay at first, but it is getting slower and slower later.

It is estimated that it is a virus, and the virus is killed first.

1 is a virus.

2 There are Trojans.

3 There is a problem with the system installation.

It should be a problem with the system, otherwise the failure will disappear after restoration.

I think the system is a problem, and it may be that I have fallen into some weird Trojans.

1. First of all, check whether the fan is blocked by dust and other things, and the speed is abnormal. If there is, it will be clear.

2. Check whether the CPU fan wiring is correct. Generally, the CPU fan that cannot be detected by the motherboard and the motherboard is set to self-protection will prompt. Get it right anyway and in the right place.

3. The fan speed is not enough. Point some lube, not too much.

4. If it doesn't work, change the fan, but it is not recommended to remove this alarm in the BIOS.

When the newly bought computer is turned on, it shows that the fan is faulty, and the possible reasons are as follows:

If it is a brand computer, it may be that the fan interface is loose and the contact is poor during the process of moving the computer, or it may be that the packaged things have fallen into the chassis, or the useless power cord inside is mixed and cannot operate normally, just open the machine and check it.

If it is an assembled compatible machine, it may not be installed during the assembly process, the interface contact is poor, and the fan itself is faulty, etc., this error will occur, you can find the merchant to check the reason, if it is a quality problem, you can ask for an exchange or return!

Question: What should I do if this happens to my computer?

The answer is not the system or fan adjustment, but, boot always enter the BIOS, in this case, it is generally caused by BIOS setting problems, it is very likely that the coin cell battery on the motherboard is out of power, in this case, BIOS can not save the settings, so, boot you need to enter BIOS to reset, and then, and then re-enter the system on it, if this is the case, it is recommended that you replace the battery to solve it.

To ask a question about the steps I need to handle, click **.

Ask if you want to re-set the details of what you can say.

The answer to this is probably caused by the battery is dead, the so-called reset is basically the default, now it is recommended that you replace the battery to try, and then restart the system to see if there is any such situation, the previous encounter is basically a battery problem, you go to change the battery first, change the battery in the boot.

Determine the type of cooling fan installed on the main computer, whether it is a direct fan connected to the power supply or a temperature control fan linked to the motherboard; The prompt is usually a temperature-controlled fan.

If you use a temperature-controlled fan, or a light pollution fan, pay attention to the lower interface, which must be directly with the motherboard, and if there are few interface pins, it is not recommended to consider it, mainly because the system cannot recognize it.

After installing the temperature control or light pollution fan, the corresponding control software must be installed in the system, which is generally installed in the motherboard driver CD.

You have reported an error, check whether the fan and control software are normal.

1. It is normal for novices to sound the computer fan.

2. During the operation of the computer, the fan is running all the time, if the fan is abnormal or the temperature is too high, it is mostly not good for heat dissipation, you can add a radiator to try.

4. Finally, the position may be offset due to excessive dust accumulation of the exhaust fan or loose fixing screws, you can clean up the dust and re-fix the screws.

Generally, if it is a new computer, the fan rings normally, if you feel that the sound is unacceptable, you can contact the after-sales service to check whether the fan has quality problems. Bucket potatoes with.

Your CPU fan speed is normal, generally above 2000 is normal, it is estimated that there will be the following reasons for the problem you said:

1. The machine has been used for too long, and the silicone is gone, so replace the silicone.

2. Medium viruses, some viruses will cause the CPU to overheat. Kill viruses or reinstall the system.

3. The machine is in a state of load for a long time, for example, the configuration of the machine is not high to run high-end games, resulting in excessive load on the processor.

Of course, it is recommended that you take apart the case and ship the machine to carefully observe whether the fan is running, as the test software can sometimes have errors.

The reason why the fan is loud after the laptop is turned on is generally because it has been used for too long, the coil of the fan is aging, and there is a lack of oil. It can also be due to improper use, impact or vibration that causes the bottom shaft to bend.

The solution to the loud fan after the laptop is turned on is as follows: first pry open the place with the interface on the top of the keyboard, then disassemble all the screws at the bottom, take off the keyboard first, then take off the optical drive from the rear, take off the hard disk, you can disassemble it to see the cooling fan, and clean the hot fan.

1. What should I do if the laptop fan is abnormal.

There are two main reasons for the abnormality of notebook fans, one is the notebook power supply fan, the other is the notebook CPU fan, and the other is the additional chassis cooling fan. Of course, many times the laptop fan is loud and buzzing, and you need to consider whether the hardware in the case fixes the screws to see if there are signs of loosening, and then take a look after tightening it.

1. Power supply fan.

The power supply fan will have a lot of dust after being used for a long time, these dust can cause abnormal noise in the notebook, at this time, you can disassemble the notebook and clean up the notebook accordingly, the role of the power supply fan for the entire notebook is the role of heat dissipation, generally after a long time, the sound of fan rotation will be loud, and you can also wipe some oil on the fan.

2. CPU fan.

Open the notebook you can see that the cooling fan and heat sink accumulate a lot of dust, on the one hand, these dust affect the heat dissipation, on the other hand, it affects the operation efficiency of the CPU, when the notebook runs too much calculation, the running speed of the CPU cooling fan is accelerated, so the fan sound is loud, therefore, you need to clean the CPU cooling equipment regularly.

If the above two methods have not worked after trying, it means that the notebook has been running at full capacity several times, and it is recommended that you upgrade the necessary accessories, such as CPU and graphics card, etc., to make your notebook run large software and games.

If this happens, use the methods described below to rule it out.

Shut down, unplug the mains power supply, remove the battery, open the case, clean the fan outlet of the case, remove the fan, remove the dust, see if the fan blades are deformed, lubricate the fan motor bearing, put on the fan as it is, start the test, if the sound is still big, the fan is seriously worn, send it for repair, or buy a new fan that is the same as the current use.

Reasons why the fan is loud:

1. If the use time is too long, the coil of the fan is aging and there is a lack of oil.

2. Due to improper use, the central shaft is bent due to impact or vibration.

3. The position of the fan is offset due to excessive dust accumulation or loose fixing screws.

4. Power supply problem.

Loud Solution:

1. Dust removal Generally speaking, newly bought fans are always less noisy, and they will become significantly larger after a period of use. In fact, dust is one of the main causes of fan noise, because pervasive dust can always penetrate into a chassis that is not completely sealed. When the CPU fan spins at high speeds, the vortex effect makes it easy for dust to adhere to the fan.

There is no doubt that it is necessary to remove the CPU fan and clean it properly at this time, and when removing dust, everyone should pay attention to the gap between the back of the fan and the heat sink, which is the easiest to forget.

2. Add lubricating oil For oil-impregnated bearing fans, it is common for the motor drive shaft to become inflexible after a long period of work. For this reason, it is recommended that you add lubricating oil to this location, and it is recommended to use mechanical lubricants or gasoline engine oil. Of course, care must be taken when adding lubricating oil and never allow it to spill.

3. Reduce vibration In addition, the vibration problem also needs our attention, usually the high-speed rotating fan will have a high-frequency collision with the heat sink, if the fan and the heat sink are stable and appropriate, the vibration and noise caused by the collision can be greatly reduced. For example, holding a CPU fan that spins at high speed in your hand is much less noisy than holding it to a heatsink because the soft human hand absorbs a lot of vibration. According to this principle, adding a 1 2 mm thick soft gasket (such as leather and rubber) between the four corners of the fan and the contact surface of the heatsink can effectively reduce the noise caused by the vibration of the fan and the heatsink.
