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.
