I had downloaded Crimson stable Dec 3 after installing my R9 380. And it had Lock my fan in to just 20% just about overheating my new GPU. I'm currently using cyst 15.7.1 and my card is stable. I also used Space Engineer as a test and Crimson really made the game ugly on top of things. This Vs my current R9 380 and from R9 270x all running on my 7850k with 2133 8 gig ram stable as a rock.
I have had Crimson working with my R9 270x and it worked fine. Don't ask me the Version I cann't remember.
R9 380 is now in my computer and running fine. I think you have a major driver Issue when fresh install of driver just about killed my new GPU. I hope you Fix this and install Majorly Glitched for the install should not take 20-30 mins just get the drivers on the Computer.
I also did try beta Crimson with my R9 380 and it still frozen fan speed.
Maybe try using Afterburner and manually editing the fan speed settings?
If you experiencing any major issues with Crimson revert back to previous CCC drivers . I myself had major issues with power consumption with the Fury X and Crimson. I'm using 15.7.1 at the moment. Hope this helps.
