series or parallel?

I'm setting up water w/ one of those 5 1/2" bay resivours & am curious what kind of difference there is between taking a new feed off for each waterblock vs running them in a series cpu/chipset/vga w/ eheim 1250.

I have it set for new feed for cpu & chipset, but was considering scrapping the chipset waterblock for a gpu one for my 9800pro. My mobo has active cooling for the northbridge anyways.

btw...my cpu waterblock is a DD RBX & i'm not sure how much that effects water volume w/ all other blocks to be DD as well...unless someone suggests a nice block for my gpu

MCW 50. Much less restrictive.

You shouldn't have blocks in parallel, especially the RBX. It's very restrictive, and water is like electricity, it goes through the path of least resistance. Meaning you are starving the flow to the cpu waterblock.

Chipset water blocks are pretty useless. They aren't really necessary.
