4.6 Chassis Installation
4.6.1 Airflow
WARNING:
Airflow is critical to the cooling of the CPU and other onboard
components. The chassis in which the NANO-PV-D4251/N4551/D5251
must have air vents to allow cool air to move into the system and hot air
to move out.
The NANO-PV-D4251/N4551/D5251 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.
