Installing the Processor Heatsink Module
(PHM)
Once you have assembled the processor heatsink module (PHM) by following the
previous instructions, you are ready to install the processor heatsink module (PHM) into
the CPU socket on the motherboard. To install the PHM into the CPU socket, follow the
instructions below.
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 of the
PHM, turn the PHM upside down. With the LGA-lands side facing up, you will note
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 of
hollow triangle.)
2. Carefully align pin 1 (the triangle) on the the PHM against pin 1 (the triangle) on the
CPU socket.
3. Once they are properly aligned, insert the two diagonal oval holes on the heatsink
into the guiding posts.
4. Using a T30 Torx-bit screwdriver, install four screws into the mounting holes on the
socket to securely attach the PHM onto the motherboard starting with the screw
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
LGA-lands and the processor.
