Expert insights on fan lubrication: The right lubricant for optimum performance

what to lubricate the fan with?
I read somewhere so as not to use solids only technical oil ...

It seems to me that the lubricant for this purpose is better .. only what ....
in the store I have a few to choose from, but the seller is not able to help me :(

they are smart from AG CHEMIA

TC
TF
LSM

and some ...

which one to choose ... or maybe it's better technical oil ??

Hello

Oil only, unless the fan is on bearings.
They usually have bushings made of porous sintered and in these pores the oil that lubricates them is kept (until it is used up). Solid grease clogs these pores (channels) and the bushing, the fan seizes up after a very short time.
Clean the dirt with a drop of oil (which I'm not sure) and the year must be spinning.

It seems to me that I do not know what fan you mean, because I lubricate the fan in the power supply differently and on the processor differently, but I also make mixtures here and there. Why, I think you don't need to explain. This is my behavior. Maybe others do differently (and probably the most important thing is to take it apart for a secondary cleaning and only lubricate it, I assure you that it stays longer than many of the original ones) and it results in a good time effect. Greetings.

the bushings are so associated that they are made of phosphor-bronze and graphite, so they use graphite grease, but a drop of machine oil will not hurt

hmmm

how complicated is the processor or graphics card fan ??

I looked at it under the magnifying glass and no channels or anything else :(

an ordinary sleeve in it, a pin from a spike ... a pin and the end ...

but oki already greased him with some graphite grease .. but he acted strangely .... works a little and the flap ... as if it was losing its lubricating properties and it starts to howl .... on all the valves i have there so it's probably the fault of the lubricant .. .

So what .. I can try technical oil for machines .... or some car oil ??

I use technical oil, in the absence of edible oil and everything flashes as it should.

WD-40 or similar preparations can be used.

I recommend castrol spray oil, something like wd 40 but a little better and it doesn't rinse out that fast

Hello,
I would have my hands cut off for lubricating computer fans and .....
Where did the lubrication fashion so widely used by "computer service professionals" come from ???
The fan after working a certain time according to the catalog note should be replaced, not lubricated, glued there, patted there and it will be somehow ... until ..
Do you feel sorry for graphics cards, processors, power supplies ???

Yoshi .. the valve on the card should come from at least as much as the warranty card has ..... and only 6 months is it .... the only thing I had to renovate at home and I could not give up the computer for a month ... and I was slightly disturbed ..... iwc I have no choice but to lubricate:]

[quote = "Yoshi"] Hello,
The fan should be replaced after a specified period of time according to the catalog note, quote]

Standard guest type from the site.
Only that I have a fan with 486 80x80 and so far I mean - a few times it was lubricated silently, as a rule, it depends on what speed it is running, etc.

maybe I am not a computer specialist, but electric machines .. As far as I know, the phosphorus bushings do not lubricate .. and certainly not with graphite grease. I recommend the latter for springs and bolts
probably in worn-out engines, lubrication with bearing grease can temporarily improve the engine operation, but for how long?
good luck in your experiments !!!

... dear colleagues, exchangers, cutters, cutters and those from catalog notes, i.e. guests from computer services (tricksters). How does it relate to the situation with me on my computer. I bought the computer at the end of December and the fan on the slinger is boxed and for a few days every time the computer starts, the fan is whirring, humming, of course, then everything is good. Tell me how it relates to the warranty, specification or catalog note. After all, it did not last even six months and there is nothing to talk about, write about and who to curse on. I am asking you just not spreading proponents ??? Best regards for sensible lubricators!

Hello,
I am not an employee of any computer repair shop.
I use SUNON fans, I don't know, maybe I'm lucky but the fans of this company have been working for me for about 4 years, about 10 hours every day. When they start to growling, I replace them with a new model.
Twice a year I dismantle the computers and vacuum them inside with a vacuum cleaner and a brush.
Unfortunately, most of the components bought by users buy the cheapest product, unfortunately I cannot afford cheap things, maybe because I am poor, according to the proverb.
In the case of processors, graphics cards, such a product should be returned to the service or store, it is subject to exchange, it is under warranty !!!

I use edible oil and there was never a problem and I have lubricated it with several hundred pieces.

I lubricate with esso universal oil, even the bearings that often start to noise after applying normal oil, do not apply edible oil on it, it will crumble afterwards will freeze

When spreading with edible oil, it is like using varnish (which were just produced from edible oils with the addition of hardeners a long time ago) - the cooking oil dries and hardens after some time

Are you saying that the fans have an expiration date ?? - you succumb to marketing gimmicks ...

Only those fans are useless if they get stuck, and then even lubrication does not help them, because the bushing is worn and the axle has too much play. It is also different with bearing ones, but the fan will run for many years if lubricated on time.
I use oil for precision machinery. However, I do not recommend castrol spray oil or WD40 - they are solvent based (you can read on the packaging) so they evaporate, thicken and become nasty. I once left a dozen castrol drops in an open container. After a week, it was twice as small, it was dirty and terribly sticky. I will not mention the cooking oil ...
The bushing and the axis of the fan should be immersed in liquid oil (lubricants fall off), which, thanks to the adhesive forces, can stay between them.
Original Intel windmills are the best! Anyone deny it ?? I once stripped one out of curiosity - they float in pure oil.

They do not have an expiry date, only the guaranteed working time stated in the catalog note. So far, I and a few people have not been disappointed.

... yes, you are right if you add that they are from the Intel stable (boxes) because I have always had them and it was like you wrote, but now I left for the first time to the side and immediately fell into disuse after a few months. greetings

Hello

"Artur79" and can you see the transistors in the prock?
It is a special sinter, unless made in xxx, it can be any material.

this is just a fan on the graphics card ... MSI so I do not suspect that it is noname .... I used machine oil .... technical oil .... so far it sits quietly:] nice ... we'll see how long. ....

And fortunately not edible as advised by "Ingenious Dobromir". Rely on your technical knowledge and not on such "patents"

hehe

not edible I did not even take into account:]
I was just wondering if something liquid (technical oil or some car oil) or a solid lubricant. After small tests of oils and technical oil, I gave up the oil ... the oil has more penetrating properties and more grip ... and the fan has a sliding bearing, so it fits quite well, so it's the "something" that lubricates must get there and stay there. ... the oil was easy to get rid of ... but the olive oil was kept sharp under the wiping of various sinters, etc. ... I gave up the solid samarium because after inserting the propeller into the bushing, everything was pushed out and only a light layer was left, which in turn was very was developing quickly. (another fan, once smeared with a tavern, quickly started to squeak again and nothing could cope any more, I poured oil and silence ... it goes well ... but unnecessarily because of the old graphics)

After all the pros and cons I greased with technical oil ... we will see how the fans will perform

the most important thing is to thoroughly clean (wash) of old oil, slime and other dirt first. New oil / grease may chemically react with old oil and seize up in the socket.
standard oils are vaseline (technical), silicone, Teflon, machine oils (petroleum derivatives) --- do not use solvent-borne gas nozzles, e.g. WD40 because it rinses graphite / molybdenum particles from the shells.
- with slightly rattled bushings, a thicker oil (not sticky) is required, better quality car oils for gearboxes perform quite well, and if the bushing is mixed with molybdenum and not graphite, vaseline oils must not be used.
- with very noisy bearings with a lot of play, you can lightly apply molybdenum grease to the axle (for bearings and high-speed bushings), molybdenum particles will stick into the pores of the shell and fill in its deficiencies and repeat this procedure after a few hours of work, then we do not give any oils,
- sometimes there are very red shells, in them the sliding material is copper and you can buy oils with the addition of copper.


In any case, do not use anything that is sticky (some petroleum-based, silicone oils / greases), the oil should be dry-slippery to the touch.

A decent fan, as someone above wrote, works for several years. With a fan for 8 to 10 PLN, you cannot expect a long service life. Do you lubricate? - lubricate but in private equipment - for the customer taking care of his good - equipment, we replace the fan with a new one, if possible, a newer, better model.

Synthetic oils for rotary lobe pumps are good - they are rare, penetrate well, are durable and not very susceptible to various types of solvents (this can sometimes be a disadvantage). In addition, they are resistant to high temperatures and have a low vapor pressure.

I use Kuyavian oil and the fan on the graphics has been around for about 1.5 years. I recommend.

I will join the supporters of lubrication and I will say that there is a saying, "whoever lubricates, drives".
I cannot imagine not lubricating devices that have any bearings.
However, I strongly do not recommend any inventions such as cooking oil, graphite grease, etc.

If you do not have the appropriate grease for a given type of bearing, a drop of a good synthetic, not too thick (preferably for precision machines) is better than nothing.

Lubricate gentlemen and you will go longer.

Greetings to all lubricants.

I use LSM molybdenum grease, it is quite rare (I mean, of course, the consistency and not the presence of ) and is a compromise between grease and oil. Moreover, it has a very big plus - it does not collect dust.
