Three of the four Amiga 2000's that we have developed noisy fans within 30
days.  About 10 minutes with a screwdriver and some 3-in-1 oil cured the
problem.  I don't think that the bearings were proberly lubricated during
manufacture.

I realize that price is important in picking hardware conponents but I think
that using a sleeve-bearing fan in the 2000 is a mistake.  There is little
difference in price between a sleeve and ball bearing fan, but a very large
difference in the lifetime.  Considering the damage that a non-operational
fan can do to the innards of a computer it seems to be a poor compromise.
