Chapter 3: Maintenance and Component Installation
Installing the Processor Heatsink Module
After assembling the Processor Heatsink Module (PHM), install it onto the CPU socket:
1. Align hole 1 of the heatsink with the printed triangle on the CPU socket. See the left
image below.
2. Make sure all four holes of the heatsink are aligned with the socket before gently placing
the heatsink on top.
3. With a T30 Torx-bit screwdriver, gradually tighten screws #1 - #4 to ensure even
pressure. The order of the screws is shown on the label on top of the heatsink. To
avoid damaging the processor or socket, do not use a force greater than 12 lbf-in when
tightening the screws.
4.
Examine all corners to ensure that the PHM is firmly attached to the socket.
