5.5 Chassis Installation<br />

5.5.1 Airflow<br />

WARNING:<br />

Airflow is critical to the cooling of the CPU and other onboard<br />

components. The chassis in which the <strong>PICOe</strong>-<strong>9452</strong> must have air<br />

vents to allow cool air to move into the system and hot air to move out.<br />

The <strong>PICOe</strong>-<strong>9452</strong> must be installed in a chassis with ventilation holes on the sides allowing<br />

airflow to travel through the heat sink surface. In a system with an individual power supply<br />

unit, the cooling fan of a power supply can also help generate airflow through the board<br />

surface.
