Water Cooling Routing help!!!

So...

After reading all the pro's opinions, I am stuck at these two options:

A.

B.

The reason that I am not sure is because I do not know whether it matters for the different blocks to pass through their "assigned" radiator before passing onto the other one.

In this case, I am using the RX240 to call the two MSI 7970 lightnings and EX240 for the i7-3770K.
In A, I am kind of forcing the PMP500 to pump to the CPU block and let the route do its normal job, and in B, I am kind of using the EX240 to cool the two graphics cards and RX240 for the 3770K.

I am not sure whether it is relevant but will A runs in a cooler temperature than B actually?? :confused:

Flow is not the only measure. The pump provides the motive force to the fluid. The pump intake has a fluid head equivalent to the height of the reservoir or possibly the height of the case. The output side of the pump has a head equal to the pump capacity ie 2-4m or 6-12 feet.

If the pressures were equal across the pump there would be no need for a pump at all. It makes sense for the higher pressure to do the most work, pumping across the restrictive blocks.

The overall flow rate is a constant agreed, but the pressure will drop (head loss) around the loop at each point away from the pump with losses at each component part, pipe, fitting, block, bend and radiator. Basic fluid dynamics.

Any slight air bubble will increase the compressibility of the fluid and it is at the slowest point in the circuit where it will have the most effect.

so on the one hand you say that you realise that flow speed will be constant, you then talk about pressure at a certain point as if it's important to flow rate, and you also talk about the "slowest point" in the loop

there is no slowest point in the loop, it is a loop, for water to move at one end it has to also move at the other end, by the same volume, that is how water works in a closed system

the total resistance in the loop will be a constant, regardless of loop order, the total pressure drop through the whole loop will be constant no matter the order of the loop, the flow rate will be constant no matter the order of the loop

and you shouldn't have air bubbles anywhere, they are very easy to diagnose and shift

go with the simpler of the 2... the water in the whole loop will equalise in any case, it doesn't matter what order it goes in
