What fans? Do you care about noise? What temperature are you willing to accept on the processor?
Thermochill are considered the best. Whether this is still true, I do not know. They were taken over by xspc who changed parts of the design, so I consider it untrusted until I see reviews showing the new design to be as good as the old.
Feser are the major alternative. I prefer (and use) these, they use G1/4" holes like everyone else, haven't just been taken over by another company, and offer cad models on their website. So I suggest one by feser.
You probably want to look at two radiators, a 480 or a 420 radiator though.
