Question 2: What lubricating oil should be added to the power fan of the computer? The rotating speed of the power fan is very high, so it is necessary to add oil with a certain viscosity or grease for instruments. At present, there are two main types of power fan bearings. One is an oil-bearing copper bearing (without balls) made by powder metallurgy technology. After adding oil, the micropores of the copper bearing will absorb the oil and store it. If the viscosity of the added oil is too clear, it will quickly evaporate and dry up. There is also a kind of ball bearing, which needs high-grade grease instead of the most common butter, which is too sticky. Adding engine oil can be used for a short time.
Specific refueling preparation work and steps are as follows:
1 Tool preparation:
Remove the 1 Phillips screwdriver for the fan; Small tweezers and blades are used to seal oil; Oil (sewing machine oil that is too thin cannot be used. Automobile engine oil is the best, and vegetable oil can also be substituted. ) two or three drops. If it is a ball bearing, please prepare grease, 5mm square is enough; Multiple napkins for cleaning and wiping; Brushes (paint brushes, combined brushes) are used to clean fan dust.
2 refueling steps:
Remove the fan from the power supply → Clean the dust and wipe it clean (to prevent the dust from falling into the bearing hole) → Open the oil seal made of the fan cable box and the trademark on the side of the skeleton, and put it away for standby → Drop 1~2 drops of engine oil on the shaft and bearing, and rotate the fan by hand while dripping oil until the rotation is flexible and inertia → Wipe off the oil outside, otherwise the oil seal will not stick → Stick the oil seal. Come on, it's over.
Question 3: What is the best oil for chassis power fan? Hardware store buys lithium-based grease. It is the safest and most cost-effective.
Oils such as sewing machine oil and clock oil can be added, but the disadvantages are too strong fluidity, easy loss and poor thermal stability. So it's best to add grease.
If Gong cares about the price, he can use a higher-grade automobile anti-wear agent, and the effect is very good.
There are butter (calcium-based, preferably lithium-based butter), vaseline, erythromycin eye ointment, collar net, dabao, etc., which can make do, but there are also many shortcomings.
Do not add cooking oil, high temperature coking will entangle the bearing.
Question 4: What oil can be added to the computer power supply fan to lubricate the high speed of the fan? Need to add a certain viscosity of fan bearing special grease, which is available in our oil mill.
If not, automobile light oil, sewing machine oil and transformer oil can be used instead. However, these oils are relatively thin and have a short service life. It's best to add some grease, which will have a good effect.
Never use cooking oil, because it will thicken after a period of use, which will make the fan unable to rotate.
Question 5: What oil should be added to the computer CPU fan, graphics card fan and power supply fan when they are noisy? I have a lot of machines, such as CPU fan, video card fan and power fan, which have been used for a long time and make a lot of noise. I use many years of refueling experience for your reference! 1. The use effect of sewing machine oil is not obvious. After three months to a year, the fan will not work, and it needs to be refueled, because the sewing machine oil is not sticky and will soon dry. 2. The butter is too sticky, which will generally affect the running speed of the fan. 3. Automobile/motorcycle oil has high temperature resistance and high viscosity, and can be used for coils or bearings. 4. Unless necessary, it is ideal to use special oil! But it is hard to see it every day, so I have to make a special trip to buy it. Such as high-pressure oil and high-grade automobile oil. Poor heat dissipation of fans is generally caused by increased dust or lack of lubricating oil. Try to clean the dust on the fan before refueling, and then consider refueling if the effect is not obvious. Do not add cooking oil. Ordinary engine oil and sewing machine oil can be used to repair bicycles. Let's talk about how to refuel first Tear off the sticker on the fan shaft first, and then pry open the small rubber plug in the middle with a small screwdriver or tweezers to drop oil into the shaft. Don't add too much, just one drop is enough. Then put the rubber plug in place and put the label on the back back back. If the adhesive is not sticky, you can stick it with a small amount of glue. Turn the fan to let the oil in. After the fan rotates for a few seconds, the oil will enter the metal hole and then the bearing. You will find that the fan rotates faster and quieter than before.
Question 6: How to oil the computer power fan? The center of that piece is made of rubber. Just stir it with a needle.
Question 7: What kind of oil is suitable for computer addicts? Please confirm whether the video card fan, CPU or power supply fan responds to the processing.
To confirm whether the power supply fan is ringing, please follow the following steps.
Turn on the power (be sure to cut off the power), take out the fan and carefully tear off 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 for watches is better), but not too much to prevent the fan from rotating and discharging oil. Finally, stick a sticker. Ok, if there is no oil hole on the back of the fan, there must be a bigger round soft rubber plug in the center of the back. Pin out the plug and connect the fan rotor (with fan metal rod). Take it out and clean it up, then coat some solid lubricating oil on the smooth metal bar, then coat lubricating oil on the concave parts at both ends of the stator (the parts with coils on them), install the stator and rotate it twice to make the lubricating oil uniform, and finally install the plug and stick a sticker OK.

Tear off the sticker and oil it. Please make sure that the back of the fan is clean, otherwise the label will not be attached.
Oil in moderation, not too much.

Some fans (such as video cards) are magnetically suspended and cannot be lubricated. This fan sound is completely caused by physical collision (for example, the fan power cord is in slight contact with the fan).
Question 8: How to add lubricating oil to the power fan and what kind of oil should I add? It is best to add some motor bearing oil first and turn the fan by hand for a while. When you feel lighter, you can get some butter to plug the hole, so that the liquid oil will not flow out, and the butter will slowly melt into the bearing, at least once a year.
The above is suitable for all fans. The fan of the power supply does not need to disassemble anything. Just remove the dust cover behind the power supply and you can refuel.
Question 9: The computer electric fan is too noisy. Where should I add lubricating oil? What lubricating oil is the best? To clean the computer fan, please make sure that the video card fan or CPU or power supply fan is ringing. To ensure that the power fan is ringing, please turn on the power as follows (be sure to turn off the power. The voltage is very dangerous). Take out the fan and carefully peel off the label on the back of the fan. If there is a small hole in it, drop a little liquid lubricant into it (sewing machine oil and watch oil are better). But not too much, to avoid oil when the fan rotates, and finally put a sticker on it. Ok, if there is no oil hole on the back of the fan, there must be a bigger round soft rubber plug in the center of the back. Hook out the plug with a needle, pull out the fan rotor (the metal rod connected with the fan), clean it up, and then apply some solid lubricating oil to the smooth metal rod and apply it to the stator (the part with the coil on it). Apply lubricating oil to the concave parts at both ends, install the stator and turn it twice to make the lubricating oil uniform. Finally, install the plug and label it. Note: Take off the label and grease it. Please make sure that the back of the fan is clean, otherwise the sticker will not stick. Oil properly, and don't attach too much. Some fans (such as video cards) are magnetically suspended and cannot be lubricated. This fan sound is completely caused by physical collision (for example, the fan power cord is in slight contact with the fan).
Question 10: How to refuel the computer power supply fan? The fan bearing is short of oil and electricity, and there are fans on CPU and graphics card, which will cause such problems, especially because the latter two are relatively high in temperature when working, and the lubricating oil inside is easy to evaporate. At the initial stage of fan start-up, because of poor lubrication, it will make a sound. If it rotates for a long time, the remaining lubricating oil in the fan bearing will cover the bearing surface and form an oil film, which will no longer sound. Uncover the label paper on the fan and put a little oil in it with a toothpick, and the problem can be solved. Be careful not to order too much, or the high-speed rotation of the fan will spread oil everywhere. Then it is preferable to cover the label paper 2.
