User Service Guide, Third Edition - HP Integrity cx2620 Server

Power Supply Cooling
Cooling for the power supplies is provided by the 60 mm fans mounted in each of the power
supply assemblies. Air is pushed through the power supply by the 60 mm fans and exhausted
out the rear of the chassis.
PCI-X/Mass Storage Section Cooling
One 80 mm, dual blade fan pushes airflow through the PCI-X card cage. The fan is controlled
by the room ambient temperature and runs at the speed necessary to maintain proper internal
temperature throughout the PCI-X card cage.
Typical Power Dissipation and Cooling
The system configurations shown in Table 2-7 are typical of most systems and show the power
and cooling values required for the listed components. These power and cooling values are
considered typical and not maximum for the configurations shown.
