Gently flex the processor carrier and place the remaining edge of the processor onto the retention clip and again align the processor notch with the key on the processor carrier. 3. Inspect the notches in the processor to ensure they are properly aligned with the keys on the processor carrier. 4. Remove the plastic shield covering the thermal pad on the secondary processor heatsink. 5. With the pin1 triangle on both the heatsink and processor carrier on the same corner, align the edges of the heatsink with the retention clips on the processor carrier and lower the heatsink onto the bracket. 6.
