Installing a Passive CPU Heatsink
1.Do not apply any thermal grease to the heatsink or the CPU die because the required amount has already been applied.
2.Place the heatsink on top of the CPU, making sure that the four mounting holes are aligned with those on the retention mechanism.
3.Install two diagonal screws (e.g. the #1 and the #2 screws) and tighten them until snug (Do not fully tighten the screws to avoid possible damage to the CPU.)
4.Finish the installation by fully installing all screws.
