4.3. Heat Sink
The CPU-71-15 comes with a heat sink. The heat sink mainly comes in contact with the CPU, the PCH
chipset, and the 82571EB dual Ethernet Controller that routes to the backplane. These are the on-
board chips with exposed dies. The fins aid in airflow cooled VMEbus chasses as fans must force air
from top to bottom or vice versa. The fins will channel the air and add to the surface area that is
exposed to forced air. The measurements in the drawing are in mm.
