Installing the VL-HDW-411 Heat Sink Fan
1.
Position the fan assembly
Using Figure 37 as a guide, align the mounting holes of the heat sink fan with the four
holes in the passive heat sink. Position the fan so that its power cable can easily reach its
mate – an ATX-style four-pin +12 V power connector (or equivalent).
2.
Secure the fan to the heat sink
Affix the heat sink fan using four M3 pan head screws.
Using a torque screwdriver, tighten the screws to 4.0 inch-pounds.
3.
Connect power to the fan
Connect the fan’s power cable to a four-pin ATX style +12 V IDE drive power
connector.
