Abstract
To manage heat generated by an electric circuit, a fan is provided to generate an air flow through a ducting structure over the electric circuit. For example, in a graphics accelerator card, a fan is placed in a void in the card and a ducting structure is placed over the fan and the graphics controller IC chip of the card. Air flow generated by the fan travels over the IC chip via the ducting structure to reduce the ambient temperature around the IC chip. The height of the ducting structure from a surface of the graphics accelerator card may be made sufficiently small so as to satisfy height requirements set forth in specifications such as the Peripheral Component Interconnect (PCI) and Accelerated Graphics Port (AGP) specifications.
