What core & memory speeds you running? I am getting similar Firestrike scores http://www.3dmark.com/fs/6033745
with +35% on the power limit setting, core 1,125 (+ 10.8% on GPU clock settings in CCC), & memory 1,710. I'm just using Catalyst Control Center as well. Also the temps are a little higher than mine at a lower fan speed I'd keep any eye on it. I'm getting around 72C average with the OC & fans set to 65% while gaming. It could just be case differences or something simple like that so I wouldn't worry unless the temps get higher. I will say though having the fans at 65% on my XFX DD Core 390 is much more tolerable than 75%, they are fairly loud at that speed.
Maybe try similar settings to mine with CCC to see if you can get the temp & fan speed down a little. Afterburner did not play well with my card for some reason. I installed it then started up the Witcher 3 intending on using it just as a monitor for the time being so I could get a baseline of my rigs stock speeds.When I loaded into the game it was artifacting like crazy & I hadn't even OCed anything yet! So I ended up uninstalling Afterburner & problem solved, no more artifacting in the Witcher 3. Ever since then I have just used CCC to OC my card & have gotten good results too.
