Close the microprocessor release lever to secure the microprocessor. Attention: v Do not disturb or contaminate the thermal material on the bottom of the new heat sink. Doing so damages its heat-conducting capability and exposes the new microprocessor to overheating. v If you need to remove the heat sink after installing it, note that the thermal material may have formed a strong bond between the heat sink and the microprocessor. Do not force the heat sink and microprocessor apart; doing so can damage the microprocessor pins. Loosening one captive screw fully before loosening the other captive screw helps break the bond between the components without damaging them. 7. Remove the heat sink from its package and remove the cover from the bottom of the heat sink. Ensure that the thermal material is still on the bottom of the heat sink and position the heat sink on top of the microprocessor. Press firmly on the captive screws and tighten them, alternating between screws until they Chapter 2. Installing options 23
