What lubricants can be safely added to a laptop fan or cpu fan

Procedures:
1. The center of your fan has a sticker. Remove the sticker. When removing the sticker, be sure to be extra careful. You want to place the sticker back on the fan later, so it needs to remain intact.

2. Underneath the sticker is a little rubber 'plug'. Under the plug is a little metal cylinder (most of which you can't see). This metal cylinder is made of a porous metal.

3. Drop one and only one drop of oil on the visible part of the cylinder.

4. Put the plug back in place.

5. Put the sticker back in place.

6. After you turn the computer back on and the fan whirls into life, it might take a little bit of time for the oil to distribute.


Desktop fans are replaced easily enough (they're all pretty cheap), but if this is a laptop - which often have unique/hard-to-find components - a replacement might not be feasible. So sewing machine oil might be your best bet.
