Installing an Active Heatsink

1. Locate the CPU Fan power connector on the motherboard. (Refer to the
motherboard layout in Chapter 2 for the CPU Fan location.)
2. Position the heatsink so that the heatsink fan wires are closest to the CPU
fan power connector and do not interfere with other components.
3. Inspect the CPU Fan wires to make sure that the wires are routed through the
bottom of the heatsink.

4. Remove the thin layer of the protective fi lm from the copper core of the heatsink.
(Warning! CPU overheat may occur if the protective fi lm is not removed from
the heatsink.)
5.
Apply the proper amount of thermal grease on the CPU. (
came with a thermal pad, please ignore this step.)
6.
If necessary, rearrange the wires to make sure that the wires are not pinched be-
tween the heatsink and the CPU. Also make sure to keep clearance between the
fan wires and the fi ns of the heatsink.
7. Align the four heatsink fasteners with the mounting holes on the motherboard.
8.
Gently push the pairs of diagonal fasteners (#1 & #2, and #3 & #4) into the mount-
ing holes until you hear a click. (Note: Make sure to properly orient each fastener
so that the narrow end of the groove is pointing outward.)
9. Repeat Step 7 to insert all four heatsink fasteners into the mounting holes.
