So gentlemen, my Alphaserver 4100 shut itself down with a sad announcement
about a dead CPU fan.  I have a parts mule which has donated a CPU fan a
couple years ago and I can take the second and last CPU fan from there but
then I have no more fans.

Can the CPU fan be obtained?  Can they be rebuilt?

The 4100 has a series of fans between the 3 power supply slots and the
main backplane which I found could not be easily obtained so I tore them
all apart and replaced the bearings with good results but I suspect that
the lttle CPU fans will not respond so well to attempts at repair.
