That's right folks, the official AMD Radeon Software Crimson Edition 15.12 has just launched for you to install.  This includes the fixes for fan speeds when you are using AMD Overdrive, your settings will stick and the fans will revert to normal after you go back to the desktop from an intense gaming session.  There are multiple fixes for Star Wars Battlefront, Fallout 4 and several GUI fixes within the software itself.  As always there are still a few kinks being worked out but overall it is worth popping over to AMD to grab the new driver.  You should also have less issues upgrading from within Crimson after this update as well.
