Chainsaw "bar and chain oil" in NA has no solids like lithium or calcium soaps. An almost equivalent oil is "way lube" for machinery. That is much harder to find in small amounts, and a machinist friend suggested just using bar and chain oil. That's what he uses. |

Ball or sleeve bearing? Some time ago I put some (I think) hydraulic oil in a laptop fan (don't remember which bearing type). It now has a problem starting, so grease or heavy oil may not be the best. |

It is custom fan not easy to replace because of availability. It is not about proper lubrication of good bearings. |

Axle Grease is totally wrong for this. You probably can't even get it to go where you need it since it doesn't 'flow'. Were you thinking of rear end differential lube like 80W90? That may work. If I had to go through all the trouble of disassembly to get to a fan that sounds like the sleeve bearing has excess clearance and the buzz is from running off center and out of balance I'd just replace the fan. Probably find one from a used laptop on Ebay and possibly by the whole entire laptop for the price of a new fan. Old laptops only bring $30 or so, even less with a broken screen or sold with no hard drive / battery / CD drive etc. Most laptops are a P.I.T.A. to get to the innards! Fix it correctly once! |

There are other special products such as two stroke oils, gun oils and cutting oils, which might do at a pinch to lubricate squeaky hinges say, but I'd be inclined to use them only for their stated purposes. I've used a light machine oil for fans and as far as I'm aware, they don't have soaps, and are expected to lubricate mechanisms for long periods. |
