Step 2:

Spread a proper amount of thermal paste onto the bottom of the cooling fan

heat sink. The thermal paste between the CPU and the heat sink is important for

optimum heat dissipation.

Step 3:

Place the cooling kit onto the CPU and properly align the cooling kit. Make

sure the CPU cooling fan cable can be properly routed when the cooling kit is

installed and its four spring screw fasteners can pass through the pre-drilled

holes on the PCB and the SBC support bracket.

Step 4:

Secure the cooling kit to the board and the SBC support bracket. Use a

screwdriver to tighten the four screws. Tighten each nut a few turns at a time

and do not over-tighten the screws. (See Figure 4-8)

Step 5:

Connect the fan cable. Connect the cooling kit fan cable to the fan connector

on the motherboard. Carefully route the cable and avoid heat generating chips

and fan blades.
