4. Align peek nut "A" (next to the triangular pin 1 on the heatsink) with threaded fastener
"a" on the CPU socket. Then align peek nuts "B", "C", "D" on the heatsink with threaded
fasteners "b", "c", "d" on the CPU socket, making sure that all peek nuts and threaded
fasteners are properly aligned.
5. Once aligned, gently place the heatsink on the CPU socket, making sure that each peek
nut is properly attached to its corresponding threaded fastener.
6. Press all four rotating wires outward and make sure that the heatsink is securely latched
into the CPU socket.
7. With a t30-bit screwdriver, tighten all peek nuts in the sequence of "A", "B", "C", and
"D" with even pressure. To avoid damaging the processor or socket, do not use a force
greater than 12 lbf-in when tightening the screws.

Examine all corners of the heatsink to ensure that the PHM is firmly attached to the
CPU socket.
