Regarding the water cooler, have amd changed the retention method for the heatsink between the different A64 sockets ? IE would a 754/939 air cooler work with AM2 ? I have some recolection that they did tweak things abit which meant all good 939 coolers were just with AM2. At worst case all you would need is a new waterblock, however if its anything like my thermaltake waterblock you strip off the standard air cooler mountings and put in there own including back plate, so i suspect it would work fine
