Heat-Sink Mounting Brackets
Pentium II processors equipped with heat-sink fins use heat-sink locks fastened to mounting
brackets to secure them to the system board, providing additional stability to the processor
module. See the system board diagram in Chapter 5, “System Board,” for connector and
socket locations.
To replace a heat-sink mounting bracket:
1. Remove the processor module. See the “Processor Modules” section above for details.
2. Two mounting locks on the rear side of the system board secure the mounting bracket.
Remove these locks, and then remove the mounting bracket from the system board.
3. The heat-sink mounting bracket has two pins on the bottom and four pins on the top.
The bottom two pins are of different sizes. The size of the pins and the holes in the
system board determine the correct orientation.
Insert the new heat-sink mounting bracket into the appropriate holes on the system
board. The bracket will click when it is correctly inserted. Ensure the four top pins are
closest to the processor slot.
4. Lock the heat-sink mounting bracket to the system board by inserting the two mounting
locks into the pins of the heat-sink mounting bracket, which are below the system board.
The locks will click when they are securely fastened.
Retension Modules
Pentium II processors are secured to the system board using retension modules. See the
system board diagram in Chapter 5, “System Board,” for connector and socket locations.
NOTE You do not need to replace a retension module to replace a processor module.
To replace a retension module:
1. Remove the processor module. See the “Processor Modules” section above for details.
2. Remove the heat-sink locks, if necessary. See the “Heat-Sink Mounting Brackets”
section above for details.
3. Remove the screws securing the retension module to the system board, and remove the
retension module.
4. Locate the key pin on one end of the processor slot on the board. Carefully line up the
key notch on the new retention module with the key pin on the processor slot. The key
pin on the processor slot indicates the correct orientation of the CPU.
