Normally the CCC with ATI you can regulate the fan speed of your card on motherboard.Try ATITool or RivaTuner.

The inclusion of the Zalman VF900 cooler is a great choice, but the fixed fan speed is not. Since the fan is always running at the same speed of around 1700 RPM, it will obviously lower the idle temperatures .

Try Speedfan; it’s a free software program that works with many motherboards and allows you to control fan speed(s) dynamically based on temperature. If your motherboard supports it, then it’s better than buying a hardware solution because of the dynamic control. It gives you much more control than typical BIOS fan control settings which are quite primitive.

One hardware solution is a Zalman FanMate, which allows you to set the voltage to a fan in the range roughly of 12 – 7 V.
