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.
