Zalman CNPS7700-Cu and VF700-ALCu Heatsink
The stock 9800XT cooler is not even in the ballpark! The VF700 just simply outclasses it. With the same clock settings the VF700 outscored the ATI cooling solution, I was able to clock higher with no artifacts long after they appeared with the ATI cooling. For testing temperatures I kept the clock speeds at a level the stock cooling could handle with no artifacts. The CPU was set at 250fsb during all video card tests. Since I could not vary the fan speed on the ATI based card I conducted all these tests with the VF700 operating at 12-volts.
