Installing the Fan and Heat Sink
The CPU must be kept cool by using a CPU fan with heat sink. Without sufficient air circula-
tion across the CPU and heat sink, the CPU will overheat damaging both the CPU and system
board.
1. On the solder side of the board, match the retention module base to the mounting holes
around the CPU socket.

2. Turn to the component side of the board making sure the retention module base is posi-
tioned and fitted properly under the board.
3. Apply a thin layer of thermal paste on top of the CPU. Do not spread the paste all over
the surface. When you later place the heat sink on top, the compound will disperse evenly.
Note:
• Use only certified fan and heat sink.
• Your 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 dif-
fers from the one in this section, please follow the installation guide in the package.
5. Position the CPU above the socket.
The gold triangular mark on the
CPU must align with pin 1 of the
CPU socket.

6. Insert the CPU into the socket until it is seated in place. The CPU will fit in only one
orientation and can easily be inserted without exerting any force. Use a screwdriver to turn
the screw to its lock position.

Important:
Handle the CPU by its edges and avoid touching the pins.
Important:
Do not force the CPU into the socket. Forcing the CPU into the socket may bend the
pins and damage the CPU.
