Here's the sick child (quad 700mhz, 8GB RAM, V12):

   

And here's the fan that seems to be dead:

   

This is the blower details in close up:

   

And from a little hunting (manufacturer website is still there!) - it seems to be very similar to their current products listed on this page:

From the product number on my dead fan - BD1275307B1

BD12 - Blower DC 12V
7530 - Seems to be the product housing / dimensions
7?
B1 - Ball bearing

Which matches up to the RBD7530B1, which is rated 12VDC 0.5A, 3800 rpm.

So my first attempt I guess will be to try and source a replacement fan (taking care to respect SGI wiring) and see if that brings the V12 back to life.

I tried booting headless, but unfortunately it doesn't like that - so no go till I resolve this.
