Anyway, I was thinking about the little 4" boxer fans, which 
a DS10L may not have.  A number of mid-size and larger Vax 
and Alpha systems had blowers made by EBM-Papst.  It might 
be harder to get these opened, they were not meant to be 
repairable.  The bearings are almost certainly ball bearing, 
so if you can get it apart without breaking the impeller, 
you should be able to press the bearings off the shaft and 
new ones on.
It is probably not a job to be done with the simplest of 
hand tools, however.

I've used a few of these blowers in some of my projects, but 
never had them get noisy.
