...wait, what?
Well, i've done precisely that. It's awesome. Took the entire top housing off an Apple MacBook, which gave me access to the fan and heatpipe assembly. Removed the fan from the computer, took the steel covers off and began
flushing the old oil out of the bearings with a methylated spirit.
Once the fan was clean of the old oil, I began to slowly feed in the new oil. I decided to go for something rated to last a bit longer than fan oil.

Tim Taylor would be proud.
With the new oil in the fan assembly, I cleaned away the Arctic Silver Ceramique and changed it with a metallic based CoolerMaster HTK-002. Compressed the copper transfer plates against the CPU and chipset to get any air out of the assembly and then tensioned it down. Refitted the fan and
started the machine up.
The fan got stuck for a bit (has to bleed the new oil into the bearings), but after 2 minutes running a fan-thrash test, it was spinning freely and significantly quieter than before. I left it running for 30 minutes just to let the machine cook for a while.

CPU Temperature at idle is 45C, down from 55C. Under load the temperature varies, but i've always found the temperature difference to be consistent, so with a 10C drop, and the previous load temperature was 80C, i'm guessing 70C is a safe guess.
Now that is how you fix a computer!
