Update
.. since I have been twiddling my knob
turned the fan speed down to 2555 then up to 4350 max, temp rise/fall has been minimal only about 5c.
But the noise of the fan on the lower speed is very very quiet all I can hear now is the fan noise on the graphics card humming away.

PS The only trouble is now I have a firewire port that I can't connect up to.. hmmm spose I better go and search for a pci firewire card now 8)
