So noted Mark. But I am sitting with my 9600 side door pointed right at me at floor level. and I can't hear it . I can feel the air pushed out side and back so I know the fans are running. At the 300 MHz level it does not seem to be very hot . But when I upgrade I'll reverse the fan somehow.
The bottom fan is supposed to draw cooling air in from the outside and flood the bottom drive area, the PCI area, and the processor area with cool air.
You'd logically think so, but Apple apparently don't think so. I confirmed by powering the fan in my 9600's door that the *labelled* side is the side that the fan blows *towards* in mine at least. I have 2 fans and both are the same.
With that in mind read this that my buddy sent me from the Service Manual's Take Apart section on the Side Access Door:
"Fan Assembly
Note: The fan assembly is mounted to the inside of the side access panel. Before you begin, remove the side access panel.
Important: Some original PM 8600 and 9600 units shipped without plastic baffles (p/n 922-3058). If no baffle is present, the fan will be installed as shown in the graphic at left, with the fan label facing out towards you. If you are replacing the fan in one of these units, you must order a baffle and install it before replacing the fan. (Note: all WS 9650 units will come with the baffle already installed.) Once the baffle is in place, the fan must be installed in the opposite direction, as shown here; that is, with the fan label facing in toward the sheet metal on the side access panel."

I, and my buddy are confused. As everyone here has just about agreed, having it blow into the case makes megatons more sense. It seems however that Apple insisted that the fans were refitted the "wrong" way around if replaced and that later machines actually came configured the "wrong" way around. Mine included, from memory I recall my 9600 did indeed come with a baffle and the fan fitted label side *in* facing the metal shield. And it did blow out, not in. Suffice to say it doesn't any more.
I also turned it on again and yes it isn't that loud, and it's not keeping me awake at night so I guess I'll leave it running.
