I went ahead and purchased this cooler and installed it this weekend. It overhangs the A0 Ram slot. If you turn it sideways, as one review recommended (to gain 3 deg. C. cooling), it overhangs the first two slots--not acceptable for my installation. Otherwise, it seems to work fine. CPU running at 26 deg C., but I haven't oc'ed yet.
