Caution
The heat sink has Thermal Interface Material (TIM) on the bottom. Be careful
not to damage this material when you remove the heat sink from the processor.
If removing the heat sink also pulls the processor out of the processor socket, the
processor could be damaged. Check the pins on the processor to make sure they
are not bent or damaged.
Release the processor by pushing down on the lever and then lifting the lever completely
up.
Remove the processor from the system board.
Install the new processor onto the system board, making sure that Pin 1 on the processor
(indicated by the silk-screened arrow on the corner of the processor) aligns with Pin 1 on
the processor socket (indicated by the absence of a pin hole in the processor socket), then
return the lever to its locked position.
Place the new heat sink on the processor, making sure the Thermal Interface Material (TIM)
is aligned between the heat sink and the processor, then tighten the screws that secure
the heat sink to the system board.
Connect the fan cable to the system board, then reinstall the fan.
Replace the 5.25-inch component bay into the chassis.
Replace the metal reinforcing beam/hard drive assembly, being careful not to pinch the
hard drive cables.
