Hi,
I'm looking for a good tower CPU cooling that will fit that board.
Today I have tried the: Dark Rock 3 from be Quiet but the power section was obstructing heat pipes so I was unable to mount it. As a help for others some links to the cooler page
http://www.bequiet.com/en/cpucooler/483and schematic with sizing
