Chapter 3: Maintenance and Component Installation
Installing the Processor Heatsink Module (PHM)
1. Once you have assembled the processor heatsink module (PHM) by following the
instructions listed on the previous page, align the processor heatsink module with the
CPU socket on the motherboard.
2. Align the large hole on the heatsink against the large notch on the CPU socket, the
small hole on the heatsink against the small notch on the socket. Carefully insert the
PHM into the socket, making sure that the large and small notches fit through the
corresponding mounting holes on the socket. The PHM will only fit one way. If it does
not fit correctly, remove it and try again.
3. Using a T30-size star driver bit, tighten eight screws into the mounting holes on the
socket to securely install the PHM into the motherboard, starting with the mounting hole
marked #1 (in the sequence of 1, 2, 3, and 4).
Note
: Do not use excessive force when tightening the screws to avoid damaging the CPU
and the socket.
