You will need to remove the heatsink under the following conditions:
•
A processor is installed under the heatsink and you need to remove the processor.
•
You are installing a processor in this processor socket for the first time. The system
was shipped to you with the heatsinks installed over the empty processor sockets.
The heatsinks must both be installed at all times during system operation.
Use the following steps to remove a heatsink:
1. Unscrew the captive screws on each corner of the heatsink.
2. If a processor is installed under the heatsink, twist the heat sink slightly to break the
seal between the heat sink and the processor.
3. Lift the heat sink from the system. If it does not pull up easily, make sure the screws
are fully loosened and twist the heat sink slighly again if a processor is installed
beneath the heatsink. Do not force the heatsink from the processor. Doing so could
damage the processor.
