I have this board and have posted this very question the other day. I believe that it will not fit without a mod.
On the back side of the socket there is a very tall capiciter that will most likely interfere. From what I see that is the only
issue, but I do not have the heatsink. My current heatsink is a 60mm Gladiator and it is close to the capiciter as is.
If the heatsink is about 3/8" larger on each side it will definately hit. I am thinking about getting the heatsink and cutting
that corner off.
