The 3B1's only have one fan (the right hand fan).  For some reason they
aren't very reliable.  I work for an AT&T VAR and we've had 5 or
so customer with fan problems (out of 26)  Not very good.  Even my own
personal UNIX pc was stricken with the fan-burnout problem.  Instead of
using AT&T service ($100 for the fan part alone) I went to my local Radio
Shack and bought two 12VDC fans.  The are both running now in my UNIX pc
for about 2 months (no problems...)  They are even quieter than the
AT&T fans.   I think the two fans might give extra protection, I'm not
sure though since most of the heat is on the right side (where the power
supply is).

After seeing the top cover actually WARP because of the heat, I got a 
little scared.  What if I wasn't home when this happened ? :-(
