I just received this card today and i was initially impressed, that was until the fans kicked in.
It turns out that the fans will immediately jump to 100% anywhere between 55c - 60c, even when set to manual control. I've setup a profile in Afterburner and it hasn't helped. If i set the fan speed to 50% either in CCC or Afterburner, the fans will still override this and jump to 100% at 55c - 60c. I dunno what could be causing this issue. I've tried several different drivers, using 13.2 at the minute. I have a pretty fresh install of windows, but i've yet to test this in Linux (doing it as i speak).
Would it be possible that my psu is causing this? I have a Corsair HX850.
