the golden triangle matches the socket corner with a small triangle.

down the socket lever to secure the CPU. The lever clicks on the side tab

to indicate that it is locked.

2.2 Installation of CPU Fan and Heatsink

After you install the CPU into this motherboard, it is necessary to install a

larger heatsink and cooling fan to dissipate heat. You also need to spray

thermal grease between the CPU and the heatsink to improve heat dis-

sipation. 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 14, No. 4 or CPU_FAN2,

see Page 14, No. 5). For proper installation, please kindly refer to the

instruction manuals of the CPU fan and the heatsink.
