4.7.1 System Air Channel

This section describes the E8000E-X3's system air channel.
The E8000E-X3 draws in air from the left and exhausts air from the rear. The air intake vent is
located at the left side of the chassis and the air exhaust vent is located at the rear of the chassis.
An air filter is installed over the air intake vent of the E8000E-X3. The air filter has a curved
face, large area, and small windage resistance. These features help to improve heat dissipation
efficiency.
The two fan modules of the E8000E-X3 are located back-to-back at the air exhaust vent, with
each module containing two fans. The system draws in air for heat dissipation, as shown in
