I was looking at getting one of those fans awhile back, think you plug it into one of the fan headers on the board.
75oc isn't anything to worry about, I have the 2gb toxic(880mhz core, 1300mem) and that hits 86oc
you can use msi afterburner(or sapphire trixx) to set speed up the fans a bit more than 50%, but it'll be louder.
Could i get a favor from you.
could you use GPUz and rip the bios from one of your cards and send me it please
