sorry for not repling imediatly
But as said above turn down that clock
not every card can overclock like that
and the directcuII top edition isn't even overclock that high
I get 89-90c with idle clock too, So I don't know if my videocard is faulty or it's just a normal temp.
I tried googling for an ideal gtx 670 vrm temp value but came up with nothing..
Should I try to contact ASUS (I left a message on their ROG forum but none responded thus far).
