Cooling System On The B16S; B16S Fan Operating Noise - IBM s-series Installation And User Manual

Cooling system on the B16S

Note: This section describes the cooling system in the B16S.
The fan trays in the B16S 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 58 on
page 124.
Table 30 shows the airflow and acoustic level for each fan speed setting on the
B16S. The noise level varies on each side of the chassis and is highest at the rear
of the chassis where the fans are located.
