What are you planning to cool? GPU, CPU, NB?
Start off looking at the Delta V3, which is generally pretty highly regarded (I certainly recommend it as I've got one).
You probably want an XSPC res top on a DDC ultra.
As for the rad, it depends what you want to cool, but if its only a cpu loop, you're going to be looking at a black ice extreme/ TFC xchanger 240
