He's currently developing his new project in C++ and will have a release ready soon. It's name is GPUMAGIC and it is specifically engineered not just for mining but for managing any large compute cluster which uses AMD Graphics Cards. You can get more information on it in my repository GPUMAGIC which is also the future home of the code (currently in testing and debugging)

Usage:

sudo ./amdgpu-fanspeed.sh -s [speed 0 - 100]
