5.5 Chassis Installation
5.5.1 Airflow
WARNING
Airflow is critical to the cooling of the CPU and other onboard
components. The chassis into which the IMBA-9454 is placed must
have air vents to allow proper airflow to cool the system components.
The IMBA-9454 must be installed in a chassis with ventilation holes on the sides allowing
airflow to travel over the heat sink surface. In a system with an individual power supply
unit, the cooling fan of a power supply can also help generate airflow over the board
surface.
