DEC BA11K Fan repair

The DEC fans that are now a few decades past end of life the bearing wear out.

Nemonix Engineering has made (new not refurbished) fans that are sealed so they do not dry out.  Something to keep in mind - one of the things I remember was that as the fan slows down (prior to full death) since the fan is running slower than spec it causes the mother board to over heats.  I am not a very technical p person so you probably already know this.

Warm Regards,
