The cards are set to run UP to 85c anyways, if you want the temp lower just change it in something like afterburner to aim for a lower temp (70c for example) and the fans will just spin up sooner and the GPU boost 2 wont push the boost overclock so far
ok thanks, i have looked in to it but could not find the sli with acx coolers so i just wanted to know if its ok for them to be running at 80-90c for hours on end, i dont mind the temps if they r safe at that.
