The NC-U6 might fit on both chipset parts but as we don't have this board we are unable to test compatibility with it.
Furthermore due to the location of the Southbridge and the size of the NC-U6 you'll probably have compatibilty issues with a number of video cards.
I'm sorry that I can't give you an answer with secure informations about this matter.

The Noctua NC-U6 (in NB) surely fit, but NOT if is the TRUE installed. The HR-05 sli/ifx fits perfectly beside the TRUE, but...What about first pci slot and ram? And furthermore with Noctua 8" fan...
I want to believe that fits...
All the others components we know that fits well. They are already tested by several people.
