After digging around a bit on other forums where the GA-Z77X-UP5 TH motherboard is pretty popular, I have found a few people who used the Noctua behemoth with no issue... aside from having to use low profile / no heat sink memory, of course.
I too was looking to use the NH-D14 for my build, and--as long as the case is roomy enough--it looks like we're good to go.
My bad... misread the title as *D*14, not C14. I'd assume that the C14 will fit just about anywhere the D14 will; the physical dimensions are similar according to NewEgg details pages.
If you try it, be sure to come back and let us know how it worked out! Let the rest of the internet benefit from your experience.
