Figure 4-15: Removing the processor
7. Place the processor on a static-dissipating work surface or inside an anti-static bag.
To Install a Processor
1. If necessary, remove any previously installed processor from the CPU socket. Follow the
procedures in the preceding section.
To allow the heat sink to draw away as much heat as possible from the processor base, it
is required there be a tight connection between the contact surfaces—the heat sink base
and the top side of the processor. To ensure this, it is required that a thermal grease
compound be applied.
NOTE:
For this server model, it is recommended that you use the ShinEtsu G751 brand of thermal
grease compound.
2. To apply the thermal grease compound:
a. Use a clean cloth dipped in rubbing alcohol to clean both contact surfaces. Wipe the
contact surfaces several times to make sure that there are no particles or dust
contaminants.
b. Apply the thermal grease compound to both contact surfaces.
c. Use the edge of a razor blade to spread out the grease throughout the entire contact
surface and
lightly
scrape out any excess grease.
Make sure that only a
very thin layer
is applied so that the contact surface is still visible.
CAUTION:
Applying too much grease will cause a gap between the contact surfaces. This
means that the heat sink is not even in direct contact with the processor, and therefore its
capacity to draw out heat is greatly reduced. Applying too much grease could also make the
grease squish out from the sides and go all over the processor pins or to the mainboard base
once the heat sink is installed. This may cause electrical shorts that can damage your system.
3. Install the processor:
a. Depress then lift up the socket retention bar up to a 90° angle from the processor
base.
b. Holding the processor by its edges, align it over the empty CPU socket.
Make sure that pin-1 marker (indicated by the notched corner) of the processor is
align to hole 1 of the socket (on the bottom right corner).
c. Insert the processor into the socket.
