I am having a problem in that the temperature is at 91 degree celsius.  Is there anyway to lower the temperature or is this common?

Reduce the memory clock.  Lower the voltage (if possible).  Raise the fan speed if needed.  Find a way to exhaust the hot air out of the room while bringing fresh air in.

Even in a room with 70 degree(F) air, the fan's auto settings on reference cards will keep the temperatures pretty high up there.  I believe mine would hit 89/90C if left on auto.  I turn the fan a little higher than that though.

My one gets up to 103°C before it starts throttling when the fan is set to auto. That's why I always have a custom fan profile running.

If you're running those cards inside a case then I suggest that you cut some holes in the side of the case and mount some fans so that they are blowing air directly onto the video cards if you don't already have such a setup. I mounted 2 120mm fans to blow air over my cards and it has made a substantial difference in the temperatures of the cards.

Thanks, I did a custom fan speed and it goes to 80 degree celsius constant.  Mine is inside a datacenter so I think air flow does help quite a lot.  Deeply appreciate your advice.
