Fan Headers

The server board incorporates three system fan circuits which support a total of six SSI compliant 4-pin
fan connectors. Two fan connectors are designated as processor cooling fans, CPU1 Fan (J9K1) and
CPU2 Fan (J5K1). These connectors can support CPU fans that draw a maximum of 1.2 Amps each.
Two system fan connectors can be found towards the front edge of the server board, System Fan 1
(J3K1), System Fan 2 (J3K2). These connectors are capable of supporting a maximum fan load of 3.5
Amps each. Two additional system fan connectors can be found near the back edge of the server board,
System Fan 3(J7A1) and System Fan 4 (J7A2). These two connectors are capable of supporting a
maximum fan load of 2.5 Amps per connector. With the proper Sensor Data Record (SDR) installed,
Server Management software can monitor all system fans in use.
The pin configuration for each fan connector is identical and is defined in the following table.

Note: Intel Corporation server baseboards support peripheral components and contain a number of high-
density VLSI and power delivery components that need adequate airflow to cool. Intel's own chassis are
designed and tested to meet the intended thermal requirements of these components when the fully
integrated system is used together. It is the responsibility of the system integrator that chooses not to use
Intel developed server building blocks to consult vendor datasheets and operating parameters to
determine the amount of air flow required for their specific application and environmental conditions. Intel
Corporation can not be held responsible if components fail or the server board does not operate correctly
when used outside any of their published operating or non-operating limits
