This might actually be useful because of it's size. I just did a dual Xeon build with a ATX board. I had a hard time finding coolers that fix because the sockets were so close together. Not a lot of choices for 2011 coolers.
If I were doing a rig like that there'd be no option except for a full liquid loop. Something like a Swiftech Edge that accommodates for dual CPUs would be the only thing I'd use.
