Squeezing Activation Arm - Intel Core Duo Mobile 945GM User Manual

6. Pick up the heatsink and squeeze the activation arm until it comes in contact with the base
plate that is attached to the heatsink base. This will cause the springs on the heatsink
attachment mechanism to compress.
Figure 9. Squeezing Activation Arm
7. While keeping the activation arm compressed, place the heatsink over the pins of the heatsink
backplate. Lower the heatsink until the lugs have inserted into the base of the heatsink. Slide
the heatsink over the lugs on the backplate pins so that the base is directly over the processor
die and the pins on the backplate have traveled the entire length of the channel in the heatsink
base. Slowly let go of the activation arm until the base of the heatsink makes contact with the
processor die. The heatsink base should be flat on top of the processor die.
