Removing the CPU heatsink

NOTE: The following illustrated CPU heatsink is typical of what you might have in your workstation.
Be aware that different variations of the CPU heatsinks exist, but the overall procedures listed are
sufficient to assist you in removing the CPU heatsink.
1. Shut down the system, disconnect power from the system, and remove the side access panel.
2. Loosen the four processor screws slowly and evenly. Loosen one pair of diagonally opposite
screws 1 until the screw shanks disengage from the system board, and then loosen the remaining
pair 2. Do not fully loosen one screw, and then move on to the next. Loosen all of the screws a
little at a time, being sure the processor remains level.
