11. Pull the microprocessor out of the socket.
To install a microprocessor and fan sink, reverse the preceding steps.
Important: When installing a microprocessor make sure that the orientation
indicator on the microprocessor is aligned with the orientation indicator on the
microprocessor socket.

7. Loosen the two captive screws on either side (in leaf spring enclosures) of the
fan sink.
8. With the two captive screws loosened, pivot the leaf-spring assemblies
outward and out of the notches on the fan-sink assembly.
Attention: Before attempting to remove the fan sink from the
microprocessor, note that the heat-conducting grease between the fan sink and
the microprocessor might have formed a strong bond. Do not force the
components apart; doing so can damage the microprocessor pins. Loosening
one screw fully before loosening the other screw will help to break the thermal
bond that adheres the fan sink to the microprocessor.
9. Lift the fan sink up and out of the computer, gently twisting it if necessary to
loosen it from the microprocessor.
Important:
a. Fan sink 1 and fan sink 2 are not interchangeable. Installing fan sink 2 on
microprocessor 1 will impede movement of the drive cage.
b. Be careful when handling the adhesive material on the microprocessor. If
the adhesive material on the microprocessor will be reused, do not
contaminate it. If replacement adhesive material is provided with the
replacement part, be sure to remove all traces of existing adhesive material
from the microprocessor before applying the new adhesive material.
locked position until it stops or clicks in the fully open position (90°).
Attention: You must make sure that the locking lever on the microprocessor
socket is in the fully open position before you remove the microprocessor from
the socket. Failure to do so might result in permanent damage to the
microprocessor, microprocessor socket, and system board or microprocessor
board.
