The OC in my sig right now makes the card running at 82C under 100% load.

Edit 1: this amount is so small and could be easily taken care of (eg extracted out of the case by a rear exhaust case fan)
There's a fan right on the side of the case that will suck in cool air from outside and blow it directly into the card's fan area. Hopefully it will pick up those air.
