2.1 I

NSTALLING CENTRAL PROCESSING UNIT (CPU)

Special Notice:

Remove Pin Cap before installation, and make good preservation
for future use. When the CPU is removed, cover the Pin Cap on the
empty socket to ensure pin legs won’t be damaged.

Pin-Cap

Step 1: Pull the socket locking lever out from the socket and then raise

the lever up to a 90-degree angle.

5

Motherboard Manual

Step 2: Look for the triangular cut edge on socket, and the golden dot on

CPU should point forwards this triangular cut edge. The CPU will
fit only in the correct orientation.

Step 2-1:

Step 2-2:

Step 3: Hold the CPU down firmly, and then lower the lever to locked

position to complete the installation.

Step 4: Put the CPU Fan and heatsink assembly on the CPU and buckle it

on the retention frame. Connect the CPU FAN power cable into
the CPU_FAN1. This completes the installation.

2.2 FAN HEADERS

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