Installing The Fan And Heat Sink - Kontron MBATX-945G-VGA User Manual

Installing the Fan and Heat Sink

The CPU must be kept cool by using a CPU fan with heat sink. Without sufficient air
circulation across the CPU and heat sink, the CPU will overheat damaging both the
CPU and system board.
Note:
Use only certified fan and heat sink.
The fan and heat sink package usually contains the fan and heat sink assembly,
and an installation guide. If the installation procedure in the installation guide
differs from the one in this section, please follow the installation guide in the
package.
1. Before you install the fan / heat sink, you must apply a thermal paste onto the top of
the CPU. The thermal paste is usually supplied when you purchase the CPU or fan
heat sink assembly. Do not spread the paste all over the surface. When you later
place the heat sink on top of the CPU, the compound will disperse evenly.
Do not apply the paste if the fan / heat sink already has a patch of thermal paste on
its underside. Peel the strip that covers the paste before you place the fan / heat sink
on top of the CPU.
2. Place the heat sink on top of the CPU. The 4 studs around the heat sink which are
used to secure the heat sink onto the system board must match the 4 mounting holes
around the socket.
Position each stud so that the groove faces the heat sink then push it down firmly
until it clicks into place.
Note: You will not be able to secure the fan and heat sink assembly in place if
the groove is not facing the heat sink.
