For proper installation, please kindly refer to the instruction manuals of your CPU fan and
heatsink.
Below is an example to illustrate the installation of the heatsink for 1156-Pin CPU.
Step 1. Apply thermal interface material onto center of
IHS on the socket surface.
Step 2. Place the heatsink onto the socket. Ensure
fan cables are oriented on side closest to the
CPU fan connector on the motherboard
(CPU_FAN1, see page 2, No. 3).
Step 3. Align fasteners with the motherboard
throughholes.
Step 4. Rotate the fastener clockwise, then press down
on fastener caps with thumb to install and lock.
Repeat with remaining fasteners.
If you press down the fasteners without rotating them clockwise,
the heatsink cannot be secured on the motherboard.
Step 5. Connect fan header with the CPU fan connector on the motherboard.
Step 6. Secure excess cable with tie-wrap to ensure cable does not interfere with
fan operation or contact other components.
Please be noticed that this motherboard supports Combo Cooler
Option (C.C.O.), which provides the flexible option to adopt two
different CPU cooler types, Socket LGA
775 and LGA 1156. The white throughholes
are for Socket LGA 1156 CPU fan.
