Installing the Cooling Fan-Heatsink

Once the processor is installed, the cooling fan-heatsink must be installed on top of the processor. Each
processor requires a heatsink, with its cooling fan attached, and a thermal bonding between the processor
and the heatsink, provided with the white thermal patch. The heatsink is mechanically connected to the
processor socket with both latches, mechanically making contact with processor.
1. Remove the heatsink-fan assembly from the shipping container and ensure you do not touch
the thermal patch on the bottom of the heatsink.
2. Ensure the latches are free and pointing away from the heatsink.
3. Position the heatsink over the second processor and:
a. Tilt or roll it slightly to the rear of the chassis to help engage the hook latch and then connect
the hook latch to the tab.
b. Rotate the heatsink back, placing it squarely on top of the processor and connect the thumb
latch to the tab on the base of the processor socket.
The hook latch and thumb latch both hook underneath the tabs extending from the base of
the processor socket base.
Ensure you align pin-1 of the processor with pin-1 of the processor socket or pin
damage will occur.
