2.3 Heat Dissipation System

This section describes the appearance, functions, and specifications of the heat dissipation
system.

2.3.1 System Air Channel

This section describes the NE40E-X16's system air channel.
The NE40E-X16 is divided into an upper chassis and a lower chassis; it draws in air from the
front and exhausts air from the rear. The air intake vent on the upper chassis is located above
the board area on the front chassis; the air exhaust vent is located above the board area on the
rear chassis. The lower chassis and the upper chassis are opposites. The upper chassis and the
lower chassis also have separate heat dissipation systems.
The middle area of the NE40E-X16 is for SFU slots.The air intake vent of this area is located
on the left of the chassis. Two upper SFU slots in the area draw in air from the left. When
flowing to the right, the air joins the air from the upper chassis. Two lower SFU slots in the
area also draw in air from the left. When flowing to the right, the air joins the air from the
lower chassis.
