Step 6.  Install the processor-heat-sink module into the system board socket. 
a. 
Rotate the anti-tilt wire bails inward.
b. 
Align the triangular mark and four Torx T30 nuts on the PHM with the triangular mark and 
threaded posts of the processor socket; then, insert the PHM into the processor socket.
c. 
Rotate the anti-tilt wire bails outward until they engage with the hooks in the socket.
d. 
Fully tighten the Torx T30 nuts in the installation sequence shown on the heat-sink label. 
Tighten the screws until they stop; then, visually inspect to make sure that there is no gap 
between the screw shoulder beneath the heat sink and the processor socket
Note: For reference, the torque required for the fasteners to fully tighten is 1.1 newton-meters, 10 
inch-pounds.
Attention: To prevent damage to components, make sure that you follow the indicated installation 
sequence.
