Installing and Removing a Passive CPU Heatsink
1. Do not apply any thermal grease to the heatsink or the CPU die; the required
amount has already been applied.
2. Install the 1U passive CPU heatsink (SNK-P0047PSC or SNK-P0057PSC)
at the CPU1 location with the air tunnel facing to the right (looking from the
front). Install the 1U passive CPU heatsink (SNK-P0057PS) at the CPU2
location.
3. Place the heatsink on top of the CPU so that the four mounting holes are
aligned with those on the serverboard and the heatsink bracket underneath.
4. Screw in two diagonal screws (i.e., the #1 and the #2 screws) until just snug
(to avoid possible damage to the CPU, do not over-tighten the screws.)
5. Add the two remaining screws then fully tighten all four screws.
Removing the Heatsink
Caution: Removing the CPU or the heatsink is not recommended. However, if
necessary, please follow the instructions below.
1. Unscrew the heatsink screws from the serverboard in the sequence shown.
2. Gently wriggle the heatsink to loosen it from the CPU (do not use excessive
force). Once the CPU is loose, remove the it from the CPU socket.
3. Clean the surface of the CPU and the heatsink to remove the used thermal
grease. Reapply the proper amount of thermal grease then re-install the CPU
and the heatsink.
