4. Cooling Sub-System
The system components that make up the cooling sub-system include: five managed
40x40x56mm dual rotor fans, two 40x40x28mm power supply fans, a CPU air duct, and an air
baffle. Together, these components provide the necessary airflow needed to meet the thermal
requirements of the system when operating within specified thermal limits. See Table 44.
System Envi
ronmental Limits Summary.
In order to maintain the necessary airflow within the system, the air baffle, CPU air duct, and the
top cover need to be properly installed.
Note: The Intel
®
Server System SR1560SF does not support redundant cooling. Should any of
the fans fail, the system should be powered down as soon as possible to have the fan replaced.
4.1 Five-Fan Module
The system includes a fan assembly consisting of five managed 40x40x56mm dual rotor multi-
speed fans. Four fans provide the primary cooling for the processors, memory, and the second
and third hard drive bays. The fifth fan provides the primary cooling for the components in the
full height PCI zone.
Fan replacement and removal of the entire fan assembly from the system does not require the
use of any tools. Each fan within the assembly can be replaced. Neither the fan assembly nor
the individual fans within it are hot-swappable. The server must be turned off before any of the
fans can be replaced.
Each fan within the fan assembly has a 10-pin wire harness which, depending on the system
configuration used, connects to either a hot-swap backplane or a system fan board. Each
individual wire harness provides the fan with power and includes tachometer lines allowing the
fans to be monitored independently by Intel
®
System Management Software.
