I have seen pictures of people using one tube staggered between cards (Picture #1)

and two tubes between each of the GPU's (Picture #2)
 
But for the life of me cant wrap my head around using two tubes between each card
 
I know that water (Like electricity) takes the path of least resistance
so If i used two tubes in between it seems like
water wouldn't flow thru one of the cards very good.............True/False ?
 
If false
Can someone explain why one way is better than the other

I run all my loops as in the top photo in Series, the bottom is running parallel is all.

Thanks Buddy

I didn't know the terminology  series vs parallel
 
So I appropriate the Verbiage Lesson
 
Best regards, Rick 

Because water can't be compressed ---> Basically they both work, ---> IF *
 
* the flow rate of the pump is greater than the flow rate of the circuit, you get a pressure increase in the loop before the WB restriction and a pressure drop after each restriction.
 
Serial circuit forces warm water from the previous WB to the next ---> flow is restricted by the previous WB(s)
 
Parallel circuits force water to each WB independent of previous restrictions, without the heat of the previous WB(s)
 
However in practice, if pump flow rate and pressure along with radiator cooling is sufficient the system will reach a stable temp
 
The "advantage" I see with parallel flow is if one WB were to be "clogged" with a flow restriction, then only that Card would see the temp increase and you would know where to start your cleaning
 
(WB = water block)
Signature builds
Rig 1 uses the serial terminal from EK
Rig 2 uses the parallel terminal from EK - I block the unused port
