corner cutout of the heat sink (if
there are two corner cutouts on one
heat sink, either will do).
5. With a little pressure, push the four
corners of the carrier down to
engage their latching features with
the corresponding corners of the
heat sink. You might hear a clicking
sound when the latch clicks into

6. Go through the four corners to check

latched, the corners of the carrier
should be tightly attached to the
heat sink, and no gap in-between is
observed.
