e. Carefully close the lever to secure the microprocessor in the socket.
Note: A new microprocessor comes in a kit with a heat sink.
9. Install a heat sink on the microprocessor.
Attention:
v
Do not set down the heat sink after you remove the plastic cover.
v Do not touch the thermal grease on the bottom of the heat sink. Touching
the thermal grease will contaminate it. If the thermal grease on the
microprocessor or heat sink becomes contaminated, contact your service
technician.

a. Remove the plastic protective cover from the thermal material on the
bottom of the heat sink.
b. Make sure that the thermal material is still on the bottom of the heat sink;
then, align and place the heat sink on top of the microprocessor in the
retention bracket, grease side down. Press firmly on the heat sink.
c. Align the four captive screws on the heat sink with the holes on the
heat-sink retention module.
d. Press firmly on the captive screws and tighten them, alternating between
screws until they are tight. Do not overtighten the screws by using
excessive force. If you are using a torque wrench, tighten the screws to
1.00 to 1.26 Newton-meters (Nm) (0.74 to 0.93 foot-pounds).
Attention: If you need to remove the heat sink after installing it, note that the
thermal material might 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 the captive screws
on one side of the heat sink fully before loosening the captive screws on the
other side helps break the bond between the components without damaging
them.
10. If you have other options to install or remove, do so now; otherwise, go to
“Completing the installation” on page 29.
