I've just bought an Intel Endeavour m/board and the manual refers to
one of the header blocks as being connected to an auxiliary 12V fan.
This is not for the processor as that has a piggyback connection to
the disk power leads for the on-processor fan.  Does anyone know what
this header is for? The only thing that I can think is that there is
temperature checking circuitry on these m/boards which would cause
this auxiliary fan to cut in as required

In fact the header block is for the CPU fan.  Unfortunatly you have the
wrong power connector (5.25 drive style connector instead of 3.5 style 
connector).  The main advantage of using the on-board connector is that
through the power saving features, you can cut the power to the CPU fan
when you slow down the processor.
