Microprocessor Microprocessor orientation indicator Microprocessorlocking lever Microprocessor socket 6. Close the microprocessor-locking lever to secure the microprocessor. Note: A new microprocessor comes in a kit with a heat sink. Attention: 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. Captive screws Microprocessor 2 Heat sink Heat-sink retention module Microprocessor socket 7. Install the heat sink: a. Remove the heat sink from its package and remove the cover from the bottom of the heat sink. b. Make sure that the thermal material is still on the bottom of the heat sink, and position the heat sink on top of the microprocessor. c. Align the captive screws on the heat sink with the holes on the heat-sink retention module. Chapter 4. Installing options 41
