Thermal Considerations

EBX-38 Hardware Reference Manual



Using the figure below 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 is on the side

nearest the J24 CPU fan connector. The CPU fan connector is located between the Mini

DisplayPort connector and the microSD socket (see Figure 2 on page 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.

Connect power to the fan



Connect the fan’s power cable to the J24 CPU fan connector on the Viper board.
