2Hold the processor carrier assembly with the
gold contacts facing up, then align the holes
of the processor carrier assembly with the

3Align Pin 1 of the PHM with the printed triangle on the CPU socket.
Make sure all four holes of the heatsink are aligned with the socket,
then gently place the heatsink on top of the CPU socket. Press all four
rotating wires outwards and gradually tighten the four screws to ensure
even pressure.
Examine all corners to ensure that the PHM is rmly attached to the
socket.
