Installing the Processor Heatsink Module (PHM)
1. Once you have assembled the Processor Heatsink Module (PHM) by following the
instructions listed on page 29, you are ready to install the module into the CPU socket
on the motherboard. To install the PHM into the CPU socket, follow the instructions
below.
2. 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.)
3. Carefully align pin 1 (the triangle) on the the PHM against pin 1 (the triangle) on the
CPU socket.
4. Once they are properly aligned, insert the two diagonal oval holes on the heatsink into
the guiding posts.
5. 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: To avoid damaging the LGA-lands and the processor, do not use excessive
force when tightening the screws.
