How do you have a 120mm fan on a 140mm radiator in the back?

[Skanky Sylveon]

140 mm fans generally don't fit 120 mm radiators.  Are you trying to mount both radiators outside of your case?  That should be possible in theory, but in practice it's going to be a pain.  I would recommend getting a case that's a little more suited tor water cooling before investing in a custom loop.
