How to refuel the fan shaft of the first horse power supply

The center part of the fan facing the heat sink side is generally covered by a round piece of self-adhesive paper, and the round hole in the center of the fan is exposed. There is a small "C" shaped plastic card stuck on the ** bearing, this clip needs to be removed, otherwise, the rotor (including the fan blade) of the motor cannot be removed. This small clip can be removed with two pointed objects.

Be sure to keep it safe and don't lose it. Next, hold the fan blade in one hand and pull it back with the other hand to separate the stator and rotor of the motor. Take a closer look at the stator coil first, as long as it is not scorched or peeled, it can generally be used normally.

All that's left to do is to clean the bearings. The fan must be thoroughly cleaned before refueling, otherwise the fan will be extremely unstable after refueling directly. The method is to dust the stator and rotor first, and then clean it.

The method of cleaning the rotor is to remove the "O" shaped small rubber ring at the root of the shaft, and clean it with anhydrous alcohol, and then submerge the rotor in the alcohol and scrub it with absorbent cotton and take it out, put it into the "O" shaped rubber ring, and put it aside to dry for later use. After that, the stator is cleaned again. When washing the stator, it is necessary to pay attention to not let the coil come into contact with alcohol, otherwise the paint film on the surface of the coil will be dissolved, causing damage to the coil.

The method is to wrap a very small amount of absorbent cotton around a toothpick, dip it in alcohol and stuff it into the copper shaft sleeve of the stator, and wipe it repeatedly until it is clean. After the alcohol is evaporated, two drops of high-quality engine oil are dropped on the copper shaft sleeve, and one drop is also dropped on the rotor shaft, not too much. Do not use sewing machine oil, as this oil will dry out in a shorter period of time.

Finally, the stator and rotor are assembled, and the clamp is installed. The middle round hole is attached with tape to prevent dust from entering, and then the fan is fixed on the heat sink to use normally.

If the fan is louder, simple refueling can not solve the problem, most of the fans of this shaft sleeve type are due to long-term work resulting in increased clearance, should consider changing the fan to solve. Most of the places under the fan label on the power supply are not turned on, if you want to take it down, just push it out.

Take out the main fan and remove the label in the middle, and you should be able to see it. Generally, there is also a round rubber object, and then you can see the shaft when you remove it.

Regardless of power supply and PC configuration. The problem of the fan itself, one will turn and the other will not turn, it may be poor contact, or it may be that the lubricating oil of the fan is dry.

It should be a lack of power, you need a power supply with a rated power of 300 350W in this configuration, and the power supply is a bit of a small horse-drawn cart.

By the way, I would like to suggest to the friends of the ration, to choose the appropriate power according to their own configuration, and not to blindly follow the recommendation of the merchant, the merchant is mercenary.

Rated 520W is definitely not able to go to U6800GTS, it needs dual 78pin power supply cards, rated 870W is a must. If you use it like this, there is a high possibility that something will go wrong

It's just a broken fan, just change it.

Remove the fixing screws first, remove the rubber cap from the fan sticker, add a small amount of lubricating oil and seal it well.

Don't dismantle it, at most remove the grid, and remove half of the sticker on the back of the fan! You'll see the main bearing of the fan! Drop one or two drops of oil and stick the sticker back. Guaranteed much less noise, I tried.

It is the lack of oil in the fan bearing that the power supply, the CPU, and the graphics card have fans, and such a problem will occur, because the latter two are working at a relatively high temperature, and the lubricating oil inside is easy to evaporate. In the early stage of fan starting, because the lubrication is not good, it will make a sound and wait for a long time to rotate, and the remaining lubricating oil in the fan bearing will be covered on the surface of the bearing, forming an oil film, and it will no longer sound. You open the label paper on the fan, use a toothpick to put a little oil in, you can solve the problem, you must be careful, don't click too much, otherwise when the fan rotates at high speed, the oil will be thrown everywhere.

Then it's best to cover the label paper 2

You can do it yourself, use a special electric fan lubricating oil to drop a few drops to remove rust coolly, smooth.

Most of the well-known electric fan factories such as Beriaco use fully synthetic electric fan lubricants from Hotolube or Kluber. Fully synthetic base oil production, clear and transparent, colorless and odorless, low temperature resistance, no dust. Tao Satie has a 120ml white sharp spout small oil bottle, which can be dropped with a few drops, which is easy to use.

It is not advisable to use ordinary engine oil and butter, which will volatilize quickly in summer and will have an unhealthy smell.

Just shoot on it and you're good to go.

1.Open the case and see, the CPU fan is covered in dust. When you take the fan apart, you can see that the fan blades and fins are covered with dust. You should find a brush to clean the dust from the heat sink and the fan blades.

2.The plastic film at the bottom of the fan is removed. Note: Do not uncover all of them, just expose the bearing (yellow part), it is not easy to stick it after all of them are uncovered.

3.Dip a little lube and carefully drip it onto the fan bearings. Note: Three or five drops are enough, not too much, too much will overflow to the outside, sticky, but sticky dust. In addition, if the lubricating oil is spilled, it will be difficult for the plastic film to be re-attached.

4.Each drop of oil rotates the fan blades several times to allow the added lubricating oil to penetrate into the bearing. After adding oil, apply the plastic film again.

At this point, you should blow a few hard breaths on the fan blades to see if it will rotate flexibly. If it does not rotate, it proves that there is still jamming inside, and it must be lubricated again until it is fully flexible and rotated.

The mains fan should not be dripped with a yogurt tube.

Find a used disposable syringe. There are clinics outside. Or drug addicts throw it away.

The oil is best used with transformer oil (or the kind used by clock repairers). Motorcycle oil is OK, but it's too strong. The sewing machine oil is too thin. Of course, lard peanut oil is also okay, but it is volatile, easy to spoil, and not very suitable.

First use a screwdriver to disassemble the power supply of the main engine, disassemble the fan, take out the oil seal of the fan, and then, use a disposable syringe, after sucking the transformer oil, drop two to three drops, note, not too much.

After that, put the oil seal on the cover. Glue the rubber well with 502 glue. Install the power supply. That's it.

In fact, it's very easy to put oil down, just take a cotton stick and dip it in oil, just order it a few more times.

The oil is taken according to the environment, and generally there will be lubricating oil in the car at home, so just use it, but it must be the best for those who have not been used!

The power supply fan is short of oil, this problem is easy to solve, you open the power box, loosen the four screws on the fan, take out the fan, there is a label paper tear in the back, there is a hole in the middle, some are covered by a leather pad, take it away to see the spindle, use the sewing machine oil to drop two drops, don't add more, prevent the fan from burning out, don't move the electronic components inside.

It should also be noted that the transformer of the general power supply is attached to the shell, when disassembling the shell, pay attention to lighter, don't break the wire, the line from the transformer to the circuit board is generally very short. Don't add too much oil, or it may short circuit or it will become more sticky to dust.

This mom is so experienced.

She has a few fans in my house almost every year, and she can fix them all by buying a bottle of lube, and then dipping that yogurt straw in the oil and dripping it in. Drop it a few times and it will always be good...

It is estimated that the structure of those fans is similar. LZ can go and try it.

Turn on the power (be sure to turn off the power, the voltage is very high and dangerous) take out the fan and carefully remove the sticker on the back of the fan.

If there is a small hole in it, drop a little liquid lubricating oil into it (sewing machine oil, watch oil is better), but not too much, so as not to turn the fan to get the oil out, and finally put a sticker OK

If there is no oil hole on the back of the fan, then there must be a larger round soft rubber plug on the back of the fan hook out the plug with a needle Pull out the fan rotor (the metal rod connected to the fan) and clean it up, and then apply some solid lubricating oil to its smooth metal rod Then apply lubricating oil to the part where both ends of the stator (the part with coils on it) are concave at both ends, install the stator and turn it twice to make the lubricating oil even, and finally install the plug and stick the sticker OK

Note: Remove the sticker and oil it, please make sure the back of the fan is clean, otherwise the sticker will not stick.

Oil in moderation and not too much.

P.S. Some fans (such as graphics cards) are magnetically levitated and cannot be lubricated for them, and this kind of fan noise is completely caused by physical collisions (for example, the fan power cord is slightly in contact with the fan).

Remove the power supply, unplug a few cables from the computer, open the 4 screws on the power box, remove the fan inside, remove the round tape in the center of the fan, and you can see the bearing of the fan, and then look at a few drops of oil inside, remember not to add too much, OK

Same as above and preferably with grease, not oil.

For example, add butter (not table butter, but industrial grease).

The fan of the power supply has a small screw on it. Generally 4 pcs. Be careful.

Remove the fan, there is a layer of adhesive paste in the middle of the reverse side, open half of it, and then put some lubricating oil in the hole in the middle, and then dip the adhesive paste on OK, don't put too much lubricating oil.

Don't tear down the motherboard.

The small piece had an opening (a slit) and was removed by opening it with a tapered tip.

Use liquid lubricating oil, not too much, and it is not expensive to change to a new fan.

Let's get a new one.

Not much money. Why bother with that.

Besides, if you don't pay attention, something will go wrong.

Get the white label down.

Then drip oil into it.

If there is no hole, it cannot be added.

If there is a hole, you can add it.

Good luck.

The power supply fan is very noisy due to lack of oil in winter, so it is recommended to change a fan, which is only 5 yuan a fan! If you want to refuel, you can add some oil by removing the sticker, and then paste the sticker back together. It won't take a few days to refuel.
