I can't speak for Lenny, but we use a large number of 3B1s (we have over
35 in use), and have had several die from overheating when the fans went
out.  One got so hot it actually warped the case, causing the monitor to
sit at an angle.  (The fan apparently went out over the weekend while no
one was around).  The last few `fan failures' we've had were accompanied
by the machines rebooting themselves every 15-30 seconds.  The power
supply was apparently toggled, not shut down.  It didn't really seem to
do a lot of good...
