2.2 Installation of CPU Fan and Heatsink

This motherboard adopts 478-pin CPU socket to support Intel
CPU. It requires larger heatsink and cooling fan to dissipate heat. You also
need to spray thermal grease between the CPU and the heatsink to
improve heat dissipation. Make sure that the CPU and the heatsink are
securely fastened and in good contact with each other. Then connect the
CPU fan to the CPU_FAN connector (CPU_FAN1, see page 8, No. 4). For
proper installation, please kindly refer to the instruction manuals of the
CPU fan and the heatsink.
