1. Remove the protection cover of thermal interface material (TIM) or thermal grease. The
required amount of TIM has been pre-applied on the bottom of the heat sink.
2. Place the heat sink directly on top of the CPU (Figure 1) so that the four heat sink
mounting screws are aligned with and seated on the four heat sink mounting studs or nut
standoffs on the socket stiffener frame.
3. Use a screwdriver with Torx T20 bit and adjust the screwdriver torque setting to 12.5~15.0
kgf-cm (10.8~13.0 lbf-in). Before turning on the screwdriver, make sure that the screwdriver bit is
fully engaged in the cavity of the heat sink mounting screw head. Keep heat sink mounting
screw vertical during installations.
4. Tighten the two diagonal heat sink mounting screws, i.e. the #1 and #2 screws (Figure 2),
Then do the same with the remaining two diagonal heat sink mounting screws.
5. Follow the diagonal installation pattern on all four heat sink mounting screws to ensure
that the bottom of the heat sink is properly seated on the CPU and to prevent the heat sink from
tilting.
