Removing Or Installing A Front Fan - Lenovo ThinkServer TD230 Hardware Maintenance Manual

5. Place the heat sink and fan assembly on the system board so that the four screws on the heat sink and
fan assembly are aligned with the corresponding mounting studs on the system board. Make sure that
you properly place the heat sink and fan assembly so that you can easily connect the heat sink and fan
assembly cable to the system fan 2 connector (if the heat sink and fan assembly is for microprocessor 1)
or the system fan 1 connector (if the heat sink and fan assembly is for microprocessor 2) on the system
board. See "Locating parts on the system board" on page 33.
Note: Note the orientation of the heat sink and fan assembly by referring to the arrow label on the top
of the heat sink and fan assembly. The arrow, which indicates air flow, should point to the rear of
the chassis.
