The fan becomes louder and the main body of the machine heats up, is it time to clean?

Dear users, hello!

In the process of transporting the notebook, it has a heating process, and the temperature is related to the user's usage habits and environment. and so on. Generally, it is safe to boot between 45 and 65.

In summer, due to the high indoor temperature, the computer temperature will increase. If you play a large game or a 3D game in a high-temperature environment, the temperature will rise faster, resulting in blue screens, freezes, reboots, automatic shutdowns and other failures. To be on the safe side, it is advisable to take some auxiliary measures to cool down. :

Such as:"Add ***. The fan has a large heat dissipation bottom seat (pad), pay attention to the use environment, it is best to use it in an environment with air circulation (to avoid the damage of high temperature in summer) and at the same time use the following methods such as: cleaning.

IE Cache, Calendar Browsing Traces, Memory Cleanup. Try to start as few programs as you don't need or use immediately, such as QQ

Thunder. Storm Shadows. etc., reduce the burden on the system and make it easy for the computer to go into battle; Of course, it is essential to clean it regularly, so as not to cause heat dissipation problems caused by excessive dust, which will affect the normal operation of the computer (service station cleaning is charged); These methods maximize the protection of the computer while controlling the temperature.

If the problem is still obvious and has not changed after taking the above measures, it is recommended that the repair service station detect and solve the problem.

Service station address inquiry.

It's best not to dismantle it yourself, it's normal for the fan to turn on frequently when it's hot, but if it's been a long time and the surrounding environment is dusty, it's time to clean it up! Generally about 50 yuan.

Wrap up the power supply fan, use a small brush or pipe to blow off the floating ash inside, that is not easy to disassemble, open the self-adhesive labels of the other two fans to see if there is a place to add two drops of sewing machine oil will be better.

If it hasn't been cleaned for a long time.

Computer cases. Inside, there may be too much dust, causing the fan to make louder noise; It may also be caused by keeping the computer running for a long time.

Fan bearings. lack of oil, louder vocalization;

It is also possible that both situations are both, and the most mentally retarded may be that a screw is not tightened or the chassis is not placed smoothly - such as placing it on a table and other objects with cavities, it is easy to form the principle of "drum", resulting in sound amplification effect. (If this is the case, it is recommended to check all the screws and place the case in a stable, sturdy position, such as the floor.) In addition, if the top of the case is flat and there is no deflector fan or anything like that, you can press some heavy books, which can be regarded as a home remedies.

In general, it should be the CPU and.

Graphics card fan. The noise is relatively large, and it is not excluded that it is.

Chassis fan. (if any) and a power fan (generally not, after all, the power fan blades are larger and more powerful.

If the power supply fan is too noisy, note:1. The screws are not tightened, 2. There's too much dust. 3。Power quality is not good).

It is recommended to thoroughly clean the dust inside the chassis. If you have been using the fan bearing for a long time and don't care about the money, you can buy a new fan, after all, the effect is better than the old fan.

This is the time that the machine has been working for a long time.

There's a lot of dust in the fan.

You look for a little cotton swab.

Then it's a fan to wipe it.

The effect will be very good.

It's also possible that there is something wrong with your CPU fan, which is causing excessive noise.

Maybe it's not a fan problem? If you turn on the computer, the fan speed is no problem, it should not be a fan problem, how long has your computer been used, sometimes the hard disk is stuck, and the solution is to tap the hard disk shell without power, and then turn on the computer to try, and the memory module is also cleaned and plugged in again.

Clean up dust and drip lube.

Or take the fan down and find someone in the computer city to clean it up.

It doesn't affect you, but it is recommended that you change it. I'm afraid it's old.

Reincarnation because the temperature of the computer motherboard is too high and it needs to dissipate heat.

That's when the CPU load suddenly increases! If you play the game, it will be louder! Just buy a silent fan.

Maybe your computer fan is short of oil, take the fan down to see if there is a small gear-like thing under the sticker in the middle of the fan, if there is, use the peanut oil or cooking oil at home that toothpick sticks a little bit to move the fan inside (do not do more), and then install it back to boot it in the test, if you can't see the gear in the middle, you have to make sure that all the screws are all in place and whether they are loose, if it is unstable and vibrating, it will also cause the fan to become louder.

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, the newly bought fan is always less noisy, and it 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 time 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 generated 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.

This is the computer CPU temperature is too high, it needs to dissipate heat, it is normal, if the temperature is too high, it will be a blue screen directly, I often encounter it, if it is a notebook, buy a small fan to blow, if it is a desktop, it is best to remove the side panel of the host, so that it can be relieved a lot, I am like this, now it's fine.

When you install the machine, you are not careful, maybe the screws are missing, or loose, or the fan is damaged, caused by it, open the case to confirm, and then deal with it, the fan has been used for too long, and if it is aging, you will replace it.

You can fix the CPU fan briefly (5-10 seconds) when you turn it on and then release it without burning out, so you know which hardware sent it.

After a strong hair dryer blows, such as blowing a fan, dust will fall into the fan bearings, resulting in reduced lubrication and increased noise. In this case, it is generally only necessary to add lubricating oil to the fan bearing.

In this case, there is a noise caused by poor contact, abnormal operation, and multi-fan acceleration that occupies the CPU.

Because the dust greasy accumulation is too much, once the vibration displacement will lead to poor contact, to thoroughly clean the dust and greasy of the gold finger of each plug-in card, the slot must have an abrasive cloth cut small strips to scratch the contacts on both sides, especially the horizontal plug-in card. It's not enough to just clean the gold finger.

Pay attention to touch the casing first to release static electricity, and the casing should be grounded to prevent electrostatic breakdown.

1.The fan blades are displaced and solved: it is better not to touch the blades when you buy another one and install it!!

2.Pivot position, apply some oil, do not touch the fan!!

Open the case and listen to which fan is called after determining the above 2 options.

Regarding the problem of desktop consoles, all fans become louder when they are blown by strong air. Judging from the description of your problem, it should be that the fan was blown by strong winds.

1. It may be that the CPU fan is blown out. Disassemble the host and check it, you can add some lubricating oil appropriately to see if it is solved.

2. It may be that the power supply fan or the external fan of the main chassis is damaged. Add lubrication and see if you can fix it.

3. If the lubricating oil still does not solve the problem, then the only way to solve it is to replace the new fan. The price of buying a fan alone is not very much, and you can buy it for a few dollars.

If it is not broken or lack of oil, just turn off the machine and gently lift the fan blade outward to let it rebound automatically.

1.If the end of the thread is in poor contact, see if the end of the thread is damaged.

2.If there is too much dust for a long time, it is recommended to clean it once every six months.

3.The lubricating oil in the fan is dry, if you hear a loud noise, it is recommended to add some oil.

4.The heat dissipation effect of the radiator is very poor after 2 years, and it is recommended to replace it with a new one after 2 years, generally about 30 pieces.

If it's a CPU fan.

It is recommended to change to a water-cooled one.

If it's a power supply. I just changed it.

It may be caused by the aging of the fan!

If it's new! Try to see if your motherboard can adjust the fan speed!

There are several reasons why CPU fans are loud:

1. There are a lot of programs running on the computer, and the CPU worker Liang Ling has a large amount of work and needs to dissipate heat, so the fan speed is very high, and the sound is very loud;

2. If the vent is blocked, if the air flow of the vent is not smooth, the CPU will not be able to dissipate heat well, resulting in the fan needing to rotate at high speed before the key slag can quietly take away the heat;

3. There is a lot of dust inside the computer, resulting in poor heat dissipation, high-speed rotation of the fan, and loud sound;

4. The CPU fan has been working for a long time, and the sound is loud due to lack of lubricating oil.

The noise is caused by the resonance sound of the case caused by the aging of the fan, open the case and add some lubricating oil to the fan. This is generally caused by the resonance sound caused by your unqualified chassis being too loud.

1. The quality of the chassis is not good, it is too soft, and the deformation of the chassis causes the deformation of the motherboard. CPU fans and other plug-ins such as graphics cards are not firmly fixed and vibrate and emit sounds. Exclusion Method:

Conditionally change the chassis, or remove all accessories and clean them, and firmly attach all the screws of the motherboard. Reinstall the hardware.

2. The CPU fan has too much dust and the blades do not rotate smoothly; The CPU heatsink is not securely fixed. Remove the CPU fan and heatsink to remove dust, or replace the fan.

3. There is too much dust in the graphics card fan, and the blades vibrate. The method of clapping exclusion is the same as in point 2. Clean.

It should be noted here that whether it is a CPU or a graphics card fan, it is necessary to pay attention to its power cord or other internal wiring of the case not to touch the fan, otherwise it will make noise even if it does not break the blades.

5. The second is hard disk noise, which is a general hard disk with sound, but the severity is different. Its sound is different from the others, and it can be distinguished.

1. Disassemble the chassis and clean all the dust (especially in the northern region), it is best to clean it with a waste brush, and it can be cleaned cleanly with a vacuum cleaner.

2. Remove the CPU fan channel fixing screws, carefully open the CPU heat sink, you will find that the silicon ester in the gap between the CPU and the heat sink has long been dried (it has a lot to do with the high power of the CPU), clean up the dry silicon ester with a slightly moist clean supplement, and let it dry.
