CAUTION: To ensure maximum cooling for the processor module, do not touch the
heat transfer areas on the processor thermal-cooling assembly. The oils in your
skin can reduce the heat transfer capability of the thermal pads.

careful not to bend the pins on the processor module.
14 Lift the processor module off the ZIF socket.
