The Zalman Vf900 is actually a genuine product, which is better than the Vf700. There is a 'Vf900 Fatal1ty', called the Zalman FC-ZV9 Fatal1ty, that you should avoid.cwiz said:the zalman vf900 is a gimmic, its the same hsf w/ some shinny metal anodized ontop of the copper, just get the normal version, they are the same.
