I got my screen right around when it came out. The fan was quiet until few days ago. I stumbled on this topic while searching for a solution.
The first I tried to do is simply disconnecting which worked, but seeing temperature top at 78, I decided its not an option. With fan disconnected, but still inside I decided to try a smallest fan I had just sitting on the top of back gsync enclosure as you will see in the picture. This drastically lower the temperature to around 44-46. I need to find a fan that will do a better job here, but this worked. Now i need to find better implementation of that.
