Looks like if your GPU follows the reference design that this aftermarket unit would work. Might be worth contacting the vendor to verify, one way or the other. However, I think that since the HD6950/6970 are so new that you may need to wait a while for more alternatives.
That being said, how is your overall airflow in your system? Do you have the ability to install a side fan to blow cool air into the GPU/CPU area?
Alos, how hard are you OCing the GPU?
