I have a Woz GS, 4M RAM, TWGS, DMA SCSI, and AE AA, and lately I've been
having problems with my GS overheating (at least that's what I blame).  I
stuck it on the floor, so carpet was blocking the airflow...got that, things
went OK for a while, then it started again.  Looking a little closer I see the
thing has sunk into the cardboard of the album I stuck it on, so I tossed
some "lego's" under each of the feet and raised it about 1/2 inch.  No
problems since, but it still runs pretty hot.  I was thinking about adding 
the Apple fan to accent my System Saver.  Anyone have any experience with
this combination?  I've heard people say the Vulcan fan and System Saver
fan "fight" each other, so thier is less air moved.  Any input at all
would be appreciated.

Thanks,

Mike
