4.7 Chassis Installation
WARNING:
Airflow is critical to the cooling of the CPU and other onboard
components. The chassis in which the PM-PV-D4251/N4551/D5251
must have air vents to allow cool air to move into the system and hot air
to move out.
The PM-PV-D4251/N4551/D5251 must be installed in a chassis with ventilation holes on
the sides allowing air to flow through the heat sink surface. In a system with an individual
power supply unit, the power supply cooling fan can help generate airflow through the
board surface.
