The present study aims to examine the future of the thermal management of video cards in PC systems. The primary focus of this investigation is on high end video card applications in both the ATX and BTX platforms. In this article, the thermo-mechanical architecture of these platforms will be revealed along with a discussion of the power density road map of both the graphics processing unit (GPU) and video processor unit (VPU) expected to be in use until the year 2010. Recommendations of how to extend the air cooling limit for video cards in either the ATX or BTX platforms will be part of the conclusions of this study.
