Installing a Passive CPU Heatsink
1. Apply the proper amount of thermal grease to the heatsink.
2. Place the heatsink on top of the CPU so that the two mounting holes on the
heatsink are aligned with those on the retention mechanism.
3. Insert two push-pins on the sides of the heatsink through the mounting holes
on the motherboard, and turn the push-pins clockwise to lock them.
