This is normal, my 4850's run at the same settings if I leave the fans on auto. I manually adjusted the fans and setup profiles. "Quiet Desktop" keeps the fans at 35% for one of my cards and 40% for the other. This usually keeps me in the high 60's to low 70's. When playing a game I have the fans set at 65% and 50% (65 for both if crossfiring). This keeps my temps in the 70's - 80's. The cards are designed to be able to handle heat so ATI lets them run warm.
