[...] I've "temporarily" repaired a fair number of them on the motherboard... but never found somewhere to get an actual replacement fan. There should be a sticker on the back of the fan, take that off and squirt lots of WD40 at it, then play with the fan until it loosens off, you can now apply some grease if you've got it, otherwise cover the hole back up, plonk it back in place, and you should be alright for at least a couple of months.
Thanks for the tips, I'll try and give this a go tonight.
Personally I wouldn't use WD-40 without replacing the lubricant you wash out with something else, it may get the fan working quite well initially but WD-40 is more solvent than lubricant so it washes out what little is left and then evaporates itself, leaving a mostly dry bearing. Bike shops sell a spray lubricant for chains etc which works quite well...something lithium, graphite or ptfe based would do the trick. Just watch where you get it and try to contain it just to the fan bearings because it may be conductive. [...]
All this reminds me of the time I recovered a keyboard that had gone belly-up following a major coffee spill (i.e. drenched; the cup was accidentally dropped onto it).
I took its bottom off, and immersed the whole thing in hot water for several hours, shook "dry", and repeated.
Then I put the whole thing on top of a very warm radiator for a couple of days.
Then it was fine.
And it also comes back to me that I once "undid" an "rm -rf *" in / as root. I was under the false impression that I was already in the directory that I wanted to rm -rf.
When I saw the first messages about what it was deleting (like /bin) I was momentarily gobsmacked. Then a bright light flashed, and reminded me that filesystem changes get cached for a while, before being periodically (every 30 sec on that system) written out to the drive.
So I rapidly reached for the reset button. On reboot, everything was still there. On the basis that "rm -rf *" had been running about 10 seconds before I caught on, I reckon I landed on the right side of 2 chances out of 3 ...
