Well I don't think they will, it's part of the first generation of dual cards in AMD, I think. So it's still experimental. I think we'll see the changes in future CCC updates, but for now - we got what we go.
I don't wanna speak too soon but mine has been working nicely for a week now (tfu tfu tfu).
It's good temperatures for a dual card system and one that is as powerful (I think) as it is. 60-70 is fine and I'll invest in a cooling pad under the laptop for heavier gaming.
The laptop is really cheap by any standard - look at it this way:
-pioneering hardware: quadcore and dual-gpus
usually it would be 2000lt for anything like this, but now - laptops are getting more efficient and cheap. it's good news to me.
