Experience in model aircraft electric motors equipped with plain
bronze/steel bearings suggests that light machine oil (3 in one) will
cure squeals, but if the bearing has run dry to the point of chattering
and destroyed the bronze, or its its a ball race that has seized,
bearing replacement or a new motor is the only solution.
In this case if light oil doesn't work replace the fan unit complete.

Ineptocracy
(in-ep-toc’-ra-cy) – a system of government where the least capable to
lead are elected by the least capable of producing, and where the
members of society least likely to sustain themselves or succeed, are
rewarded with goods and services paid for by the confiscated wealth of a
diminishing number of producers.
