80c is definitely fine, however, 60% fan speed on the 7970's reference cooler is 3.5k RPM and it sounds like a hair dryer. 60% fan speed would keep my card under 70c. However, we are missing a couple important variables.
How warm is your room?
Are you OCing? What are the voltages and clocks?
Where's your case located? Block any exhaust or intake?
My 2x 7970s at the moment is running at 0.975v @ stock speeds so I can leave my fan profile set at 30% fan speed and it does not get above 85c after hours and hours of BF3. I am running, just like you, a 1080p 60hz Dell U2311H.
Once I OC for benches and what not and bump voltages, my fan profile needs to be bumped up aggressively. 1.131v @ 1175/1575 and I need to keep my fans spinning at 45% to keep it under 80c. If I had set my fan setting at 60% fan speed, I'd be sure to see ~75c with a decent OC but it's just loud as hell.
I am saying if you are running stock voltage and speeds, and need to keep fan at 60% to maintain 80c, something is wrong. I know my VID is great, I have a 1.05v, 86% ASIC quality card, but even if you had a 1.175 VID, you should not need to set fans at 60% at stock speeds to keep it under 80c. While your 1.175 is higher than mine, your card has more leakage so temps should even out close to me, probably a tad bit hotter, but not by much.
