Good Watercooling Pump And Radiator

[SmileyChief]

Hi guys, I'm looking for a high performance pump but I don't know which kind of specs I should be looking for in a pump. I plan on installing at least 5 rads in my case (I know that that is pretty overkill, but that's the point of the my entire build) so what kind of pressure and flow rate should I be looking for?

I have heard a lot about the D5, but are there any better ones out there and should I go with two pumps in parallel? I plan on using some 140 mm Black Ice GT Extremes and Noctua NF-A14 PWM fans. Does anyone know a better radiator? And what is the difference between the Black Ice GT Extreme and the Black Ice Nemesis. Thanks in advance

I like the D5, fom what I have heard it is one of the best. In the worse case scenario, I would get a PUMP/RES and a regular D5 that you can mount in the midpoint of your loop, to give more pressure.
