Installing a Passive CPU Heatsink
Note
: Do not apply thermal grease to the heatsink or the CPU; the required amount has
already been applied.
1. Align the four attachment screws of the heatsink with the four mounting holes on the
motherboard.
2. With a Phillips screwdriver, gradually tighten screws #1, #2, then #3, #4 to ensure even
pressure. The order of the screws is shown below. To avoid damaging the processor or
socket, do not use a force greater than 12 lbf-in when tightening.
