AMD has released version 15.12 of its Radeon Software Crimson Edition, a WHQL-certified driver that most notably "officially" addresses a fan speed issue that cropped up last month. Think of it as an early gift for the holidays.
The change log highlights a number of resolved issues. In Star Wars: Battlefront, the driver fixes flickers related to snow, broken sky renderings and shadowy texture issues in some locations of the game. Version 15.12 also addresses issues with compass flickering in Fallout 4 (although it seems AMD hasn't quite worked out a fix for Radeon R9 290 and R9 295X2 series cards) and in Just Cause 3, some texture corruption issues should now be a thing of the past.
With regard to the fan issue, the AMD Overdrive fan settings will always be set to ON after first edit on reboot. What's more, the fan speed is set to Manual when exiting from a game or application.
For everything the drivers fix, there are still plenty of known issues that haven't yet been remedied. I counted nearly 30 known issues affecting games such as Total War: Rome II, Call of Duty: Black Ops 3, Just Cause 3, Fallout 4, Starcraft 2 and Assassin's Creed Syndicate, just to name a few.
Do note that you'll need to be running Windows 7 Service Pack 1 or later in order to use these drivers. Furthermore, they must be installed either as the Administrator or with Administrator rights.
