FSX 1600
NOTE:
This section describes the cooling system in the FSX 1600 chassis. For a description of the cooling
system in the FSX 1600-ANR chassis, see “FSX 1600-ANR” on page 8-4.
The fan trays in the FSX 1600 are located in the top rear of the chassis.
The fans cool the CPU, main memory, and voltage regulators. The fans move the air from the front of the device
to the rear of the device, as shown in Figure 8.2.
Table 8.3 shows the airflow and acoustic level for each fan speed setting on the FSX 1600 chassis. The noise
level varies on each side of the chassis and is highest at the rear of the chassis where the fans are located.
