Microprocessor / fan sink Note: v Read "Safety information" on page 119. v Read "System reliability considerations" on page 33. To remove the microprocessor and fan sink, do the following: 1. Power-off the computer and remove external cables. 2. Remove the cover and support bracket (see "Removing the side cover" on page 40 and "Removing the frame-support bracket" on page 41). 3. Disconnect any cables that impede access to the processor. 4. Remove the fan sink from the processor: Note: The fan sink and underlying heat sink are attached and do not need to be separated from each other. Remove the fan sink/heat sink assembly from the processor as a single unit. a. Detach the fan sink cable. b. Loosen the two captive screws on either side (in leaf spring enclosures) of the fan sink. c. With the two captive screws loosened, pivot the leaf spring assemblies outward and out of the notches on the fan sink assembly. d. Lift the fan sink up and out of the computer. Note: It may be necessary to gently twist the fan sink to loosen it from the processor. Important: Be careful when handling the adhesive material on the processor. If the adhesive material on the processor 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 processor before applying the new adhesive material.
