Thanks for sharing :) perhaps someone will use this tutorial from your link.

And about that oil - any shop is selling it and accepting bitcoin ?: )

That would be nice!

I hope that with removing the fan from the computer no one will have problems.
In 99% of cases sufficient for regular Phillips screwdriver and a few minutes of fun.

The whole operation from start to remove a sticker located on the front fansink:

Under the label is hidden rubber plug, which is something you need to pry and pull. This can be done either tiny, flat screwdriver or needle (resp. pin):

At the corks you will see a pivot, to which are attached the blade. Axis is at the very end secured special cotter pin through which the blade does not fall out of fansink:

Cotter pin may be made of plastic and have the shape of slit ring (as in the above photo), or the metal of such a mischievous, to describe the shape of a long;) This however, is not important. Regardless of the type of pin, it suffices to undermine the one hand (with a small screwdriver or tweezers).

Contrary to appearances, the removal of this contraption is not so simple and requires'll make agility. Places to maneuver a little, and the whole thing is a slippery (literally :). There is, however, what put you off, because after a few fans takes such a practice, it can be done with closed eyes;) Pins are made of elastic material, so rather not be her break (unless that someone prejudices). These metal pin may be only a little deformed, but later you can easily straighten them with your bare hands. After pulling the pin we can easily separate the shoulder from the rest fansink:

Some of the blades can safely wash under water. Both the blade and the center can be easily cleaned an old toothbrush. Try as thoroughly clean the axle from the old grease, which can significantly slow down the fan.

Sometimes also he a magnet in the middle of collecting a large number of different metal filings (especially wind turbines in a power supply, which often pick up all the crap from the environment):

Cleaning fansink second portion is substantially reduced to one - a thorough cleaning of both sides of the aperture for receiving the pivot. You can do this around the corner cloth or cotton swab. If someone has, you can also clean the wick hole to pipe :)

Before cleaning the inlet holes see if there are any seals (in those expensive fans are virtually always). As they are, they pull out a first and a Clean all. If you have access to compressed air, it does not hurt to blow the guts fan :) As everything is cleared, we can go to oiling. Here I recommend Vaseline oil, which is not enough that it is very cheap (something around 1.5 € per bottle), it's great just for that. It's sticky enough to provide good lubrication, and at the same time so rare as not to create additional resistance. For each fan will need up to two drops of oil;) The first drop infect on the axle blades (preferably on the same tip, so as to drain the oil evenly on the wall until the end of the axle). Then Ordered Fan for together and we let even one drop of oil in the place where it was plug.

That's all. Now just put the cap (assumed to be much easier than removing;), push the rubber cap and stick sticker. When the rubber cap is a well-fitting, the label can let it go. If, however, cap sitting loosely, you need something to stick to not fall out. I myself, I stick a piece of black tape there "power tape" (also known  as the "duck tape" or colloquially "macgyverka";). Of course, the cap can seal anything. Land to plug stick;)

I am sure many miners will find this thread useful for them and for their devices.
