Just a FYI, I put my new system together last night (still waiting for video card), but the Freezer 7 Pro will not fit unless the bottom 4 fins are modified. They will push against the big'o copper heatsink next to the cpu socket.
Wow, thanks for the info, I'm about to build myself... Got the freezer pro 7 and was about to get that mobo..., I guess I have to think about others....
jerryg: You know you can remove the heatsink on the back? I imagine you could mount any large thermalright using only the hollow screws (no backplate). You would have to offload the weight somehow tho.
