Keep the water blocks for a watercooled S7 - if only that was possible! 
I like the C1 -but turned into watercooled S5's 2.2+TH/s @ 1.1KW - just upgrade the radiator and pump would be good
I am sure the C1 blocks fit the S5 screwholes.

I do recommend upgrading pump and not using syscooling one. It just has had a lot of failures. So that is good idea.
You can use original radiator and put 3 more fans on it. This makes it into a push/pull and does help cooling for pretty cheap to get the 3 fans to add.
If anyone needs it from parts one I have radiator and tubes left for sale will take fair offer - https://bitcointalk.org/index.php?topic=1169446.new#new
