Bigbruin.com published a review on the Zalman VF900-Cu Dual Heatpipe VGA Cooler

Zalman continues to innovate in the field of high performance, low noise cooling. The VF-900Cu provided excellent cooling performance and was able to do so with absolutely no noise. Even at full speed, the cooler was quieter than the stock unit it replaced, and it kept the X800 GTO almost 10 degrees Celsius cooler!
