2.2Installation of CPU Fan and Heatsink

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 1155-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 through-

holes. 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 three dif- ferent CPU cooler types, Socket LGA 775, LGA 1155 and LGA 1156. The white throughholes are for Socket LGA

1155/1156 CPU fan.
