Yes, it does raise very interesting questions.  You and I got
our 3B1's at the same time.  I've added a EIA/COMBO board with
1.5 Meg on it and a DOS73 board.  My far has only been at one
speed since day one.  If we have dual speed fans, I would expect
mine to have changed speeds after adding those two boards.

Maybe I somehow have a newer issue fan which runs only at the
single, higher speed?

I would like to know for sure that my 3B1 will shutdown safely
if my fan stops.  Someone in the know please enlighten us.
