Attaching the HFC-22 Heat Sink/Fan/Clip Assembly
The figure at right illustrates the HFC-22 mounted to the IM483H/IM805H. To
attach the HFC-22 complete the following:
1)
Placing the heat sink on the driver, align so that the dot on
the heat sink is on the same side as the dot on the driver,
with the TN-22 thermal pad sandwiched between them.
2)
Insert two of the arms from the fan/clip assembly into the
corresponding slots in the driver, aligning the curved fingers
on the clip between the posts of the heat sink. Insert the
other two locking tabs into the opposite slots and snap into
place. The locking tabs on all four arms should be complete-
ly through the slots on the driver.
