Adjust fan speed on ATI graphics card in OS X? I just got an Apple 4870 and am using it with OS X fine. However it is soooo noisy. 

Are there any software tools or firmware mods I can do to change the fan speed at various temperature thresholds?
Solved: Edited and reflashed the rom from this guide:
