2.1 I
NSTALLING CENTRAL PROCESSING UNIT (CPU)
Step 1: Pull the lever toward direction A from the socket and then raise the
lever up to a 90-degree angle.
Step 2: Look for the white triangle on socket, and the gold triangle on
CPU should point forwards this white triangle. The CPU will fit
only in the correct orientation.

Motherboard Manual
Step 3: Hold the CPU down firmly, and then close the lever toward direct
B to complete the installation.
Step 4: Put the CPU Fan on the CPU and buckle it. Connect the CPU
FAN power cable to the CPU_FAN1. This completes the
installation.

2.2 FANHEADERS
These fan headers support cooling-fans built in the computer. The fan
cable and connector may be different according to the fan manufacturer.
Connect the fan cable to the connector while matching the black wire to
pin#1.
