The computer I have with was dusted some time ago. When I dismantled it, it was broken.

It's likely that JS hurt you (do you recognize that person?). I'm not sure), which part of the fan is the whole thing? I've installed the fan myself.,It's really tight.,But there's not much chance of damaging the motherboard by removing the fan.,There's only the possibility that the edges and corners of the fan will crush the CPU.。。

In addition, the fan is only 40 to 50 yuan, which is not profitable. If you're a computer novice, you're likely to be deceived! Replace your motherboard with a garbage spot (unless it's exactly the same) and you're likely to get caught.

It's a pity that the computer city specializes in bullying people who don't understand computers.。。。 Khan, you have to be careful with this!

It's very likely that the motherboard that has been replaced is not compatible with the previous equipment.,Of course, the possibility of js is not ruled out.,Bainaohui。。。 If it's Nanjing, it's very likely...

Summary. Hello, dear, the fan turned faster after the computer was cleaned, which proves that the computer is cleaned well. The fan is back to normal working order. This is normal, the fan speed is fast to dissipate heat. So don't worry. Dear, I hope mine can help you.

Hello, dear, after the computer is cleaned, the fan turns faster and is dismantled, which proves that the computer cleans the orange and the jujube very well. The fan is back to normal working order. This is normal, the fan speed is fast, which Huai dissipates heat. So don't worry. Dear, I hope mine can help you.

The fan is particularly loud after ash cleaning.

Have you removed the fan when cleaning the ash? If the fan blade is removed during ash cleaning, the fan blade may be in contact with lack of lubrication, or the installation may not be harmonious; If the fan is not installed in place, or the screws are not tightened, the fan will vibrate or shift when it is running, resulting in a noticeable increase in fan noise. If you are very professional if you do not lack grips, it is recommended that you find a professional to check it out.

The fan will become louder when it ages normally.

A year is a long time, the fan must be cleaned, the dust will block the heat dissipation port, and the hot air will not be dissipated, which will cause the internal hardware temperature to rise abnormally, affect the hardware performance, and cause lag, especially when playing big games! The notebook I just dismantled today, the dust basically blocked the heat dissipation outlet, it was very disgusting, and I haven't cleaned it for more than a year! After cleaning up, the temperature of the heat dissipation port of the big game is significantly smaller than before, and the stuttering phenomenon has been significantly improved, and the FPS has also increased slightly by 10!

In short, it is very important to improve the performance of the computer!

The computer brand is different, and the internal structure is not the same, such as my Dell N4110, the fan is independent of the motherboard hardware, so you can clean the fan without removing the motherboard, and you can take it down separately, which is very convenient. Some are much more troublesome, and when connected with CPU and other hardware, it will be much more troublesome, and you need to prepare heat dissipation paste!

LZ can go online to view the disassembly tutorial of the corresponding computer and learn it. To be honest, notebooks are for learning, learning knowledge, if you don't learn to disassemble, it's equivalent to buying it for nothing! People who can't disassemble notebooks don't understand notebooks!

Learn slowly. Be careful when dismantling, don't come hard, but don't be too cautious, depending on your degree!

I dismantled it with the dormitory, my Dell his Acer 4750g, after the dismantling, you will know what low quality is! The internal structure of the Acer is obviously inferior to mine, and the heat vents are not copper! This affects the heat dissipation!

If the laptop is permanent, you need to disassemble the computer to clean up the dust for the following reasons:

Dust can cause the temperature to rise during device operation, affecting performance.

If it is in a high temperature environment, it may burn out the motherboard.

However, it needs to be determined based on the actual usage environment:

1. If the use environment is in a scene with turbid air, such as a construction site, the side of the road, etc., it is recommended to clean the laptop fan once every 3 months in this environment;

2. If the use environment is in a scene with relatively clean air, such as bedrooms, parks, etc., the laptop fan can be cleaned once every six months to a year in this environment;

If the laptop has a strong heat dissipation or dust removal function, it is recommended to turn it on occasionally during use, and you can also appropriately reduce the cleaning frequency of the laptop fan.

Yes, for a long time, the exhaust vent is full of dust and blocked, which will make the temperature of the CPU motherboard and graphics card rise significantly, affect the system performance, and reduce the service life of the hardware. However, the notebook is more precise, if you haven't dismantled it, you don't know how to disassemble it, don't do it yourself, find someone who knows how to clean it up.

It's okay to turn on the program card and the fan, if you feel that the machine has been too hot lately, you can indeed clean it up inside. Cleaning the fan is nothing more than dusting and refueling, and silicone is applied between the heatsink and the CPU.

It is recommended not to dismantle it yourself...

It's best to take it to a professional place to clean it up·· I usually clear it once every six months... Cleaning up the dust is mainly the dust of the graphics card and the CPU place (this affects the performance) ·· Other places are just for the sake of aesthetics

Mine is the same as you, but I suggest that you better clean up the after-sales area where you bought the computer, and don't do it yourself, after all, we are laymen and prone to problems.

Well, it is true that you need to clean up the dust, and you can go to the computer city to find a repair notebook.

If you don't know how to do it yourself, it is recommended to take the notebook to the local computer store and give someone a few dozen yuan to help you get it, which is very convenient.

The ring mirror is clean, you don't need to move it for a year, you can do it once every 3 years.

Oh, you can rest assured that in addition to the power supply, the computer uses DC 12V voltage, which will never reach you. However, I am worried that you will accidentally touch the various cables when cleaning the dust, which will cause unexpected consequences, so I recommend that you turn off your computer for cleaning.

Break a leg. Supplement: After the power supply is powered off, it can be disassembled, and it is best to place it before disassembly.

For one or two hours, let the capacitor in it discharge by itself, so as not to hit you with the residual power of the capacitor, but even if you hit it, it's nothing, just numb.

If you don't have the power off, be careful not to touch the live wire and neutral wire, and if you don't know how to do it, it's best not to touch the transformer. In fact, there is no need to clean the power supply frequently, as long as the main parts are cleaned up, but be careful anyway.

Rest assured, disassembling the power supply of the computer to clean up the dust will not be electrified, but the premise is to disconnect the AC power supply.

Disassembly method: 1. Remove 4 screws.

2. Then look for a way to turn it on. (Look carefully at the perimeter of the power supply to find out which parts are connected, generally the upper and lower structures.) can be separated).

3. After separation, sweep off the dust and blow off the dust with a hair dryer.

Note: After dismantling, don't decompose it downward, just be able to touch the dust, decompose it downward, it's easy to make mistakes.

Just blow off the dust. Blow, close, screw, uncomplicated.

In fact, to help you clean the computer, you don't need to disassemble the computer, use a blower to blow the same as new, if there is no blower, in fact, the hair dryer is a pity, and then use a brush. As for the voltage, as long as you unplug the power supply after shutting down, that's not as good as you want.

As long as the external power supply is turned off, it will not, and it is necessary to pay attention to clean up its own static electricity, so as not to damage precision components and integrated circuits due to static electricity.

Of course, there is a voltage of 220V. That's why you have to turn off the power.

It is definitely needed, and it is very necessary.

A computer, after about half a year of use, will have a layer of dust on the display. Open the main chassis, and there will also be a lot of dust inside the chassis. There is a lot of dust in the power supply, CPU, fan, various boards, etc.; At this time, if you don't pay attention to cleaning, it will cause dust to block the fan and cause the fan to stop, or cause the computer to crash or crash when running the program, resulting in the loss of data. In the worst case, it can lead to the burning of the machine's hardware, resulting in unnecessary economic losses.

Board fans and power supply fans are one of the most important places to be cleaned, especially power supply fans. Quite a few cases are designed with the power supply as an air outlet, which can cause a lot of dust to accumulate on the power supply fan. Without disassembling the power supply, you can use an ear wash ball to blow off dust from the fan.

There is a lot of dust on the graphics card fan.

After disassembly, it is even more intimidating, and the bearing can be oiled after unmasking.

Graphics card fans and processor fans also usually accumulate a lot of dust on them. The fan can be removed directly for cleaning. Many fans often emit some noise after a long period of use, most of which is due to the aging of the bearing, and generally a little oil can be applied to the bearing of the fan to reduce the noise of the fan.

It's best to clean it up.

Turn on and blow with a hair dryer.

Brush down with a soft-bristled brush.

The top of the fan is not easy to blow off.

Brush with a brush. If the CPU has a lot of heatsinks inside.

It's time to remove the radiator and clean it.

I have a lot of dust in my house.

I have to clean up a lot.

You can also use a hardware temperature check to see it.

Is your computer hot or not?

If it's not very high, it doesn't matter if you clean it up after a while.

1.Loosen all the power interfaces on the power supply and the motherboard, optical drive, and hard disk, and use an oil-based pen to indicate which is on the plug.

2.Remove the power supply, remove the fan, and classify the screws to remember which one is installed.

3.Use a large brush to clean the fan.

4.Use a leather blow (for repairing watches) to blow the capacitor and other surrounding parts clean, or sweep it clean with a small oil brush.

5.Encapsulated power supply.

6.Load into the chassis.

7.Just plug them in one by one according to the ones you just marked with your pen. You don't need to know anything about the hardware to do it.

You can see clearly, the one with the pins is the CPU, between the CPU and the fan is the heat sink, which is metal, and the fan itself is plastic.

The situation you mentioned is probably that when the machine was installed, too much thermal grease was applied, and when the silicone grease hardened, the heatsink and CPU were glued together.

Now that the CPU has been removed, you see if the pins of the CPU are broken, and if there are any broken, it can only be scrapped. If it is not broken, then use a knife to gently scrape off the adhesive between the heatsink and the CPU, or you can slowly dissolve it with alcohol, and after separating the heatsink and CPU, install the CPU on the motherboard, the method is as the friend above answered.

You also need to remove the residual silicone grease on the CPU, and then apply new silicone grease, 1 yuan 1, don't apply too thick, just a thin layer, the purpose of silicone grease is to fill the gap between the CPU and the heat sink, if you apply too much, it is not conducive to heat conduction.

There is also a buckle between the fan and the radiator, and if you look carefully, you can separate the fan and the radiator. Because there are many forms of buckles, generally speaking, there are two kinds of mechanisms, screws and folding, and you can basically understand it with your brain.

The last thing to say is, brother, you are too fierce, and it is definitely not possible to do it "accidentally" by removing the CPU.

The position should be inserted correctly, the line has a positive and negative side, and again you look at the needle and foot.

Not only did you touch the wind fan, but even the CPU was brought out, you see if the buckle of the CPU and the wind fan is broken, and whether the pins of the CPU have been removed, and if they are not broken, take off the CPU and then open the buckle on the CPU plug seat, and there is a small gap on the corner of the CPU with pins, and then press it gently, and then press the buckle down. If there is silicone, apply some CPU and flatten it, then press the radiator and buckle the clip.

1. Without silicone grease, the heat dissipation effect is very bad, not to mention that the AMD CPU generates more heat, buy it as soon as possible, and the temperature will rise, otherwise the CPU will burn back after a long time. As the temperature rises, CPU performance decreases.

2. When the fan rings, check whether it is wired or something next to the fan, if not, it may be that the fan ball is not well lubricated, it has been aged, and the fan has been replaced. Generally, the computer has been in the computer for a long time, and the fan will sound after clearing the dust, because when the dust is blown, part of the dust enters the ball, and the lubrication is not good, and there will be a sound.

Put the silicone grease on, install less junk software, and there is no such metaphysical problem.
