After hearing reports its Crimson Edition driver was causing low fan speed issues, AMD has released a hotfix driver -- 15.11.1 -- today.
The driver fixes the aforementioned fan issues, and also includes "great stability improvements" and game fixes for Just Cause 3, Star Wars: Battlefront, Fallout 4 (that compass issue is fixed except for R9 290 and AMD Radeon R9 295X2 setups), and Black Ops 3 (which sees good performance in Crossfire now).
For the full notes, hit the source, where you can also grab the driver (also feel free to grab it through the newfangled Radeon Settings application).
