Processor heatsink Removing the CPU heatsink NOTE: The following illustrated CPU heatsink is typical of what you might have in your workstation. Be aware that different variations of the CPU heatsinks exist, but the overall procedures listed are sufficient to assist you in removing the CPU heatsink. 1. Shut down the workstation, and disconnect power from the system (Pre-disassembly procedures on page 55). Remove the access panel (Access panel on page 63), and place the workstation on its side with the system board facing up. 2. Remove the two processor screws slowly, being sure to loosen the screws evenly. Loosen one screw (1) until the screw shank disengages from the system board, then loosen the remaining screw (2). Do not fully loosen one screw, then move on to the next. Loosen both screws a little at a time, so that the processor remains level. Figure 5-69 Identifying proper screw removal order 3. Disconnect the CPU heatsink fan connector (1) from the system board. Loosen the heatsink mounting screws (2). ENWW Removing and replacing components 113

Removing the CPU heatsink
NOTE:
The following illustrated CPU heatsink is typical of what you might have in your workstation.
Be aware that different variations of the CPU heatsinks exist, but the overall procedures listed are
sufficient to assist you in removing the CPU heatsink.
1.
Shut down the workstation, and disconnect power from the system (
Pre-disassembly
procedures
on page
55
). Remove the access panel (
Access panel
on page
63
), and place the
workstation on its side with the system board facing up.
2.
Remove the two processor screws slowly, being sure to loosen the screws evenly. Loosen one
screw
(1)
until the screw shank disengages from the system board, then loosen the remaining
screw
(2)
. Do not fully loosen one screw, then move on to the next. Loosen both screws a little at
a time, so that the processor remains level.
