You don't mention whether or not the fan was working.  As the owner of a 3b1
with a warped grating over the power supply, I'd bet it wasn't.  In my case,
I started a large overnight download; when I woke up I found the machine
wasn't working, and shut it off.  I don't know whether this was the result
of a fan failure, but I suspect it was.  Before the AT&T repairperson (the
machine was under warranty) arrived, my roommate tried turning the fan
through the fan grating, using a screwdriver.  He reported that he had to
force it a bit before it started turning, i.e. it had been stuck.  The AT&T
person replaced the power supply, but not the fan; it was working when she
tested it.

Eventually I replaced the fan with an AC fan.  This is a reasonable
precaution even for a machine that is working well, since the standard fans
are quite unreliable.
