   I recently gave up trying to oil a fan, replaced it with another
second-hand fan, then pulled the old one apart. It was simply full of dust
which I could have washed out easily with some washing up liquid and water,
a quick test showed that it would not have rusted. It was a specially
modified fan, (one corner hacked off and the power connections reversed),
but the replacement worked as well after the mods.

   Another source of failure is the loop-through power supply lead to
provide the fan with power. The fan often works, but the power loop-on
fails, so the hard drive starts showing errors.
