Except that AMD in their infinite wisdom
, adopted a rectangular bolt pattern for their heatsink retention and only lets you mount the heatsink in one direction. On my M3A79T board, that had the TRUE pointing towards the psu or vid card, which isn't ideal for cooling in either layout. With the Intel mounting system you have much more flexibility in mounting choices because Intel chose an square mounting pattern for both LGA775 and LGA1366. And you can get a better mount on an Intel system by using the washer method or by simply putting a couple of small strips of duct tape across the top of the base like I did. Then it won't rotate or move around easily.
