Airspirt:
After OC my 9700 for a while and using watercooling on the core, I would say that your cooler idea is only half the problem. I am sure that you are going to have to kick up the core voltage on the 9500 a bit in order to reach your goal.
Dont get me wrong, that HSF should take care of keeping the core cool enough but from my experience, a voltage mod will be enevidable for you to reach your 360 core speed.
Good luck
