Step 7. For two-processor configuration, install the 1U standard heat sink into processor socket 1 and 1U
performance heat sink into processor socket 2.
Important:
• Do not touch the contacts on the bottom of the processor.
• Keep the processor socket clean from any object to prevent possible damages.
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 screws to be fully tightened/removed is 10+/-
2.0 lbf-in, 1.1+/- 0.2 N-m.
Attention: To prevent damage to components, make sure to follow the indicated tightening/
loosening sequence.
