5.6 Fan Headers
The server board provides four SSI-compliant 4-pin and four SSI-compliant 6-pin fan headers to
be used as CPU, and IO cooling fans. 3-pin fans are supported on all fan headers. 6-pin fans
are supported on header J3H4, J3H3, J3H2, and J3H1. 4-pin fans are supported on header
J9J1, J5J1, J3H4, J3H3, J9B4, and J9B3. 4-pin fans are not supported on header J3H2, and
J3H1, since these headers are tied to the CPU1 PWM. These fan headers should also not be
used for CPU cooling fans. The pin configuration for each of the 4-pin and 6-pin fan headers is
identical and is defined in the following tables.
Two 4-pin fan headers are designated as processor cooling fans:
- CPU1 fan (J9J1)
- CPU2 fan (J5J1)
Four 6-pin fan headers are designated as hot-swap system fans:
- Hot-swap system fan 1 (J3H4)
- Hot-swap system fan 2 (J3H3)
- Hot-swap system fan 3 (J3H2)
- Hot-swap system fan 4 (J3H1)
Two 4-pin fan headers are designated as rear system fans:
- System fan 5 (J9B4)
- System fan 6 (J9B3)

Note: Intel Corporation server boards 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
