one radiator, many CPU's?

[Carnival Forces]

how do you get one radiator to cool more than one CPU?

would it have to go pump > res > cpu > rad > cpu > pump...

because then you'd have (taking out everything but rad and cpu) two cpu's next to eachother:
cpu > rad >V
^ > cpu

what i want to see is cpu1 > rad > cpu1
with , at the same time, : cpu2 > rad > cpu2
and maybe even... cpu5 > rad > cpu5

see what i mean?

there are these "magical" things called Y connectors that let you do this kind of thing. usually, they are a no-no because they lead to water following the less restrictive GPU path, and leave the CPU to heat up with less flow, but in a situation with two identical blocks, and equal lenths of tubing, it is do-able, depending on the setup of the rest of the loop.

i understood part of that post. i'm proud i got the sarcasm part

no but seriously, could you explain why they're bad and how to fix that again, i'm sorry but i don't understand..i'm a newb at this...

water inside a cooling loop will follow the path of lest resistance.

CPU waterblocks usually offer more resistance than GPU or chipset waterblocks.

if you use a Y connector to split the coolant flow between the CPU waterblock and the GPU waterblock, then most of the coolant will flow through the GPU waterblock, and not much will flow through the CPU waterblock. since the CPU usually produces more heat than the GPU, this is bad, since it causes the CPU to heat up more than it would if the coolant flowed through first one waterblock, and then the other in series.

if you use a Y connector and equal lengths of tubing to split the coolant flow between two identical CPU blocks, the flow to each block will be equal, and there is no problem of one heating up more than the other. doing this reqires that the rest of the loop be planned out to take the splitting of the flow into account, and either one powerfull pump, or a number of smaller pumps; one for each CPU.

about the only sarchastic part was the use of the term magical.

yeah, all in all your's was a very nice post. i didn't mind the sarcasm, it was funny.

okay, so it's just like headphone splitters

all right, how could i judge what speed / how many pumps i'd need? if i've done my reading correctly (hopefully i have) than pressure is just as important as "GPH" right?..so depending on the number of y-connectors/amount of tubing/number of CPUs being cooled i'll need a faster/stronger pump

..now how to figure that out..

i would think that a pump like the swiftech MCP350 or the dangerden DDC-12V for each CPU and a relatively low-restriction block like the swiftech MCW600x on each CPU combined with whatever waterblock you care to stick on the GPU (reccomend dangerden maze4 GPU acetyl top) and rad with three 120mm fans would do the job nicely for a low noise solution. a two fan rad with more powerfull fans would also do it.

the danner mag 7 offers great bang for you buck in a single pump, but it is AC and less convient.

i'm planning on doing this for my folding boxen, so i wont' have a gpu. integrated graphics, baby! ..yeah..all i need is a fast CPU to OC, so all i'll need to cool is Semprons.
