Installing The Fan And Heat Sink - DFI RM641 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 circula-
tion across the CPU and heat sink, the CPU will overheat damaging both the CPU and system
board.
Note:
A boxed Intel processor already includes the CPU fan and heat sink assembly. If your
®
CPU was purchased separately, make sure to only use Intel
sink.
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 fan / heat sink assem-
bly. 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.
Some heat sinks come with a patch of pre-applied thermal paste. Do not apply thermal
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 push-pins 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.

4. Rotate each push-pin according to the direction of the arrow shown on top of the pin.
Push down two pushpins that are diagonally across the heat sink. Perform the same proce-
dure for the other two push-pins.
