OILING THE FAN...WITH WHAT OIL??

In my previous post I explained how to access the fan to clean it and

oil it.

Since I have received several requests for more information about this topic and in particular what oil should be used, I decided to quote Daniel Rutter Blog

What you oil it with isn't too critical. Pretty much any light oil w

ill do. Plain old 3-IN-ONE or sewing machine oil from the supermarket is fine. Note that the usual red-label 3-IN-ONE that I use has a vegetable oil base, and may gum things up if used over and over. This isn't likely to be a big problem with fan bearings (it's usually only an issue in automotive and other high temperature applications), but if you're concerned then you should get the blue-label mineral based version.

Spray-can oils with an applicator tube can be handy for oiling fans in awkward spots, if you can avoid spraying oil all over the place.

Do not, however, use WD-40 or similar products. WD-40 is has great

penetration, displaces water well, and loosens rust - but it's a lousy lubricant. It's mainly kerosene, and the oil that's left when the kerosene evaporates may be more than adequate for stopping a gate-hinge from squeaking, but won't last long in a fan bearing.

Remember that you can access the fan from the top or from the back.

From the top it is on your left:

COOLING SYSTEM:CLEANING THE FAN

Hi.

Some people asked me how to remove and clean the fan. Some people have noticed that it makes a lot of noise and it needs cleaning and oiling.

Actually, I did not remove the fan, my vaio fan was also making a lot of noise. What I did was to carefully vacuum clean the fan and everything else around (except for the microprocessor and the side of the cooling system that makes contact with it)

you can see that you can reach the fan (up-right-side) and you can clean it and oil it (carefully not too much) without taking it away.I did it and it is much better now.

If you need to remove the fan and replace it, this will probably require fruther work, since it looks like the whole case needs to be removed. I haven't done this but I think it can be done.

If any body has done it please send some tips and photos.

good luck

ATTENTION!!!! be very careful not to touch (and not remove) the white paste which is meant to create optima thermal coupling between the CPU and the cooler. So DO NOT REMOVE THE WHITE PASTE. ALSO, do not touch the CPU unless you are planning to change it by another one compatible, it is very easy to dammage it only with your fingers, and remove the white paste with your fingers...do not do it.

OPENING THE MAIN BODY - PART TWO (2): COOLING SYSTEM

So what you see below is to show you how to remove the cooling system once you opened the previous lids (explained in part 1) and removed remaining small screws. Very important, in any of the following pictures I did not used a screwdriver, I just used my hands, slow and smoothly....no forcing. And even more important, do read this complete post before doing it yourself.





lift the cooling channel by pushing up the left side and holding down the right side, turning it 40 degrees approx.

At this stage you can remove the complete piece, the cooler.
It looks like this after cleaning (with a vacuum cleaner or a soft cloth)
