You Sure?

ok what about having the tubeing splitting off into the the different water blocks then joining up after and going thro the rad, would this be better than goin from the CPU,to the GPU to the Chipset block then to the rad? e.g.
1: Pump> Res> Splits too CPU/GPU/Chipset > Rad>Pump
2: Pump> Res>CPU>GPU>Chipset>Rad>Pump
Also would it be more restrictive in the first diagram?
And Fluid XP any good? or is there something else thats better?
