4.4 Chassis Installation
4.4.1 Airflow
WARNING:
Airflow is critical to the cooling of the CPU and other onboard
components. The chassis in which the SPCIE-C2260-i2 must have air
vents to allow cool air to move into the system and hot air to move out.
The SPCIE-C2260-i2 must be installed in a chassis with ventilation holes on the sides
allowing airflow to travel through 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
through the board surface.
