Which mining software are you using? Many miners support controlling the card directly through their interface. I found BFGMiner to be very effective, and you can set both forced/manual clocks, fan, voltages, or set a range for autotuning based on GPU temps...

Try Sapphire Trixx, or switch to BFG or cgiminer
