Chapter 3: Maintenance and Component Installation
Installing the Processor Heatsink Module (PHM)
1. Locate the triangle (pin 1) on the CPU socket, and locate the triangle (pin 1) at the
corner of the PHM that is closest to "1." (If you have difficulty locating pin 1, turn the
PHM upside down. With the underside of the CPU facing up, you can see the hollow
triangle located next to a screw at the corner. Turn the PHM right side up, and you will
see a triangle marked on the processor clip at the same corner as hollow triangle.)
2. Align pin 1 (the triangle) on the the PHM over pin 1 (the triangle) on the CPU socket.
3. Align the two holes at diagonal corners of the PHM onto the two guide posts on the
socket bracket and carefully drop the PHM onto the socket.
4. Use a T30 Torx-bit screwdriver to install four screws into the mounting holes on the
socket to securely attach the PHM onto the motherboard in the sequence of 1, 2, 3, and
4, as marked on the heatsink label. Gradually tighten each to assure even pressure.
Note
: Use only 12 foot-pounds of torque when tightening the screws to avoid damaging
the processor or the socket.
