Help Adding GPU block,what flow is better?

[OPUS1]

I'm gonna add the EXOS GPU cooler VID-NV1-L06,
What is a better piping setup?:
Run the water to the CPU then the GPU then back or
Split the flow so that one line goes to the CPU and one line goes to the GPU and
then back to a splitter?
I am using the EXOS AL 1/4" tubing
Thanks

I've always heard that the CPU should get the coldest part of the water first.

and then the GPU and so on...

NEVER try to run parallel as the flow will be split based on hydraulic resistance...you would need to balance the flow in order to get good temps on all components. Just run to the CPU and then to the GPU in series. Most watercooling loops have no more than a 1-2C temperature increase in the water. My advice is to run the lines in what ever way is the easiest with the SHORTEST lines. I always try to go from the rad to the CPU to the GPU to the pump back to the rad.

Just run everything in series, there isnt any real big temp difference between block when in series, and with blocks in parralel, more of the flow will got to the least restrictive block, making the other block(s) run much hotter.
