If cooling both the vid card and cpu(and maybe the chipset,have a block but not gonna use it right away)is it better to run my hoses in series or to use a Y or T fitting to splice the flow with 1/2 to cpu and 1/2 to vid card?I have a 1/2" system with an Eheim 1250 and DD maze 2-1,chipset and vid-card blocks.
