Step 3: Lock the Retention Mechanism
Push down the locks on the retention mechanism to secure the heatsink and fan to
the module base. When secure, the retention locks should point to opposite
directions. The heatsink should entirely cover the CPU. With the added weight
of the CPU fan and heatsink locking brace, no extra force is required to keep the
CPU in place. Connect the CPU fan cable to the fan connector.
Step 4: Connect the CPU Fan Cable
With the fan, heatsink, and the retention mechanism in place, attach the CPU fan
cable to the connector on the motherboard labelled CPUFAN.
