CHAPTER 2: HARDWARE INSTALLATION
2.1 Install Central Processing Unit (CPU)
Step 1: Locate the CPU socket on the motherboard
Note1: 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.
Note2: The motherboard might equip with two different types of pin cap. Please refer below
instruction to remove the pin cap.
Step 2: Pull the socket locking lever out from the socket and then raise the lever
up.
Step 3: Remove the Pin Cap.

Motherboard Manual
Step 4: Hold processor with your thumb and index fingers, oriented as shown.
Align the notches with the socket. Lower the processor straight down
without tilting or sliding the processor in the socket.
Note1: The LGA1155 CPU is not compatible with LGA 1150 socket. Do not install a LGA 1155 CPU
on the LGA 1150 socket.
Note2: The CPU fits only in one correct orientation. Do not force the CPU into the socket to prevent
damaging the CPU.
Step 5: Hold the CPU down firmly, and then lower the lever to locked position to
complete the installation.

2.2 Install a Heatsink
Step 1: Place the CPU fan assembly on top of the installed CPU and make sure
that the four fasteners match the motherboard holes. Orient the assembly
and make the fan cable is closest to the CPU fan connector.
Ensure the fastener slots are pointing perpendicular to the heatsink.
Step 2: Press down two fasteners at one time in a diagonal sequence to secure
the CPU fan assembly in place. As each fastener locks into position a click
should be heard.
Note1: Do not forget to connect the CPU fan connector.
Note2: For proper installation, please kindly refer to the installation manual of your CPU heatsink.
