Advice 1: What to lubricate a computer fan

A faulty fan can reduce the life of the computer, not to mention the fact that he produces a lot of unnecessary noise. To computer lasts longer, the fan should be lubricated with oil.
What to lubricate a computer fan
Most computers are equipped with three fans. One is in the power supply, the second - in the case of the computer, and the third in the Central processor.

A faulty fan can be identified by the noise.
Fans needed to cool the system. If at least one of the fans stops working, the system can overheat, and some of the information may disappear.

The first impulse may be to replace the cooler. But this is often not necessary. You can just lubricate the faulty fan, and that's enough for a single drop of oil.

How to choose oil

Wrong choice of oil for the fan may lead to complete failure of the system. Many people use WD-40, special grease, developed by the American company to lubricate all kinds of squeaky and noisy surfaces. But it is not necessary to use this tool for computer fan.

It helps only in the case that smeared the subject, rarely are in motion, for example, the hinge of a door. But the fan is in constant motion and rotates at a high speed.

Better to use a household lubricating oil intended for sewing machines, power tools, door locks, hinges.
There is a special oil for sewing machines. It is light and tough, can withstand high temperature and are specially developed for the lubrication of parts working at high speed.

The principle of operation of the fan

Most fans kept on sliding bearings consisting of a shaft, which rotates inside the cylinder or sleeve.

The cylinder consists of a porous metal, oil lubricated. When the shaft begins to rotate, the portion of the oil sleeve is moved closer to the shaft, creating an oil film. So the metal part is almost not touching, not damaged, and noise is almost not audible.

Ideally, inside the cylinder always has enough fluid, and the fan does not wear out. But some production costs, for example, if the bearing is poorly made, the part of the oil evaporates. Then the fan will work slower, parts of it begin to RUB against each other and wear out, the computer will overheat. Noise will occur.

In this case, you should put in a cooler one drop of oil.

How to lubricate the fan

To lubricate the fan, need to disassemble the computer and remove the cooler. Put the fan on a table and carefully remove the sticker. Part of the sticker is right above the gap for the wires. Hence it is easier to bend.

Remove the middle fan of the rubber stopper. You can use a small screwdriver, gently bringing her over the edge of the tube.

You will see in the resulting deepening of the shaft end within the cylinder. Drip one drop of oil in the recess.
Just one drop is enough, no need to pour oil into the bearing.
Refit the rubber tube, tape it on top of the sticker. Sometimes the sticker ceases to flatter. Then you can use ordinary tape.

After getting the fan back in place, the computer has run for a few minutes before the oil is fully oil cooler. After some time, the computer will run quieter and longer too hot.

Advice 2: How to lubricate the fan

As you know, the fan or cooler is a very important component of your computer. It regulates the temperature of the processor and does not allow him to overheat. The sound the computer fan is known to all. But if one day you notice that the sound has changed, for example, your computer started to buzz as the plane on takeoff, it means that the fan clearly needs help, i.e. cleaning and lubrication.
The cooler regulates the temperature of the CPU and gives it to overheat
Remove the bolts using a screwdriver, disconnect the connector, remove the fan from the housing.
With a brush or cotton swab to gently clean the blades of the fan and its housing. Remove all accumulated dust and dirt.
The fan housing should have a round sticker. Peel off the label. Under it you will find a rubber cork. Very carefully remove it without damaging.
Under this band you will find the bushing and fan axle which you will need to lubricate. To do this, take the spindle or machine oil. You can also use the joint. For lubrication, apply a little oil on the axle of the fan.
The oil should cover it, but not drip too much, because otherwise, when applying the rubber tube, the oil can flow out of the recesses and stain the body, then the sticker will not stick to you back. To more precisely apply oil and it has not spread, you can use a medical syringe. In this case, the lubricating oil must be very liquid to freely flow through the syringe.
Grease the can and the inner part of the fan, but it will have to completely disassemble. We strongly advise you to do it yourself, if you are not an expert – layperson will not be able to cope with such delicate work, and you risk to ruin the cooler.
Now carefully pull the rubber stopper in place, making sure the oil is not flowed and not contaminated the case. Carefully and gently wipe the housing from contamination. Then replace the round sticker.
It happens that the sticker after peeling lost their shape or just not glued in place. It's not terrible, replace it with a piece of ordinary stationery tape, just cut it in shape and size.
In reverse order install the fan in place and connect the connector.
Now efficiency of the cooler will increase significantly, it will work once purchased. But remember that after some time from thermal effects, the grease will evaporate, therefore we perform this procedure regularly. Good luck and good work for your cooler!
