The Intel Server Board S5500BC incorporates a system fan circuit that supports five SSI
compliant 4-pin fan connectors. The two 4-pin fan connectors are for processor cooling fans:
CPU_1 fan (J3K1) and CPU_2 fan (J7K2). The three 4-pin fan connectors are for system fans
system fan 1, system fan 2, and system fan 3 (J3K2, J8K3, and J8B4). The pin configuration for
each fan connector is identical. The following table provides pin-out information.

Note: The Intel Server Board S5500BC supports peripheral components and contains a
number of high-density VLSI and power delivery components that require adequate air flow to
cool. Intel designs the chassis to meet the intended thermal requirements of these components
when the fully integrated system is used together. If Intel server building blocks are not used in
the system, it is the responsibility of the system integrator to consult vendor datasheets and
operating parameters for the air flow requirements for their specific application and
environmental conditions. Intel Corporation cannot be held responsible if components fail or the

Intel Server Board S5500BC does not operate correctly when used outside of the published
operating parameters.
