The new heat spreader design also is attached differently; most heat spreaders are one-piece designs held in place by the use of clips that go over the top - OCZ previously used this setup. Since the new design is separate on each side, the heat spreaders end up being directly attached to the memory chips. The heat spreaders still make the DIMMs a little wider and hence easier to install into the memory slots. As you can also see, the new "honeycomb" design should allow for better ventilation - you can see the outline of the memory chips beneath them..
