Have sent the mobo for rma, the temps of the 5850 were under 80C at all time.
That's surprising. Roughly how long and how much use was your board setup with the 4 way CF? I don't recall anyone else experiencing this problem so hopefully its just an isolated occurrence. Hopefully the RMA process will go smoothly with MSI.
