3.7 Heat Dissipation System

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

3.7.1 System Air Channel

This section describes the E8000E-X8's system air channel.
The E8000E-X8 draws in air from the front and exhausts air from the rear. The air intake vent
is located above the board area on the front chassis; the air exhaust vent is located above the
board area on the rear chassis.
An air filter is installed over the air intake vent of the E8000E-X8. The air filter has a curved
face, large area, and small windage resistance. These features help to improve heat dissipation
efficiency.
