2 outputs 1 input

[Staplez107]

Hello, I have a simple yet hard to google question. I am looking to redo my cooling loop, but I want the output to split into two outputs 1 going to the CPU, radiotor, and then res. The other going GPUs, radiator, and then the same res. Is this possible I have an EK D5 Reno pump and the ex-res 400. Like I said the input for the pump will be from the res, the output will split into two loops.

EK has some, 2 actually

both are in 3 different colors

Yes it's possible, but I wouldn't recommend it. Water will travel in the path of least resistance and so the flow split will only be 50/50 if the resistance in the split is exactly the same, which it won't be.

 

So you will be risking one part of the loop receiving much less flow than the other half.

I agree with this.  It's fine if you're splitting through identical GPU blocks but not through different components.  Can you get away with it?  Probably.  Is it ideal?  No.

As said it can be done and the main thing would be to ensure the restriction between the block is similar to ensure both get proper flow.

I did consider that but more of what I mean is directly out of the oumpnthe connection splits. One path going through the GPU (1) and the radiator (1) and one path going through the the CPU and the other radiator(2) and both ending up back in the resevoir. I didn't state it before, but my case is a corsair 900D and my pump is on the bottom of the case.

You would see no appreciable benefit from that in terms of temps, by splitting the rads and blocks since the fluid moves around the loop so fast.

Oh I know that it's for aesthetics. Before I did it I want to ensure it wouldn't hamper my flow on one loop or the other. Kinda hard to tell though some believe it will on other forums some don't. I may get some soft tubing and just test it. I'm worried it will do it on the CPU side since it's higher in the line going to a top radiator. But I have a flow meter that wouldn't be moving so I may test it.

If you wanted to fill up the openness of the case a separate dual loop would work well. I would suggest to just have the blocks all parallel and radiators series together, that will ensure a somewhat similar restriction so the flow will be close to the same between all the blocks.

Well I already have a massive reservoir that almost fills the length of the case. But I may have thought of a path that can work and still look aesthetically pleasing. Without disrupting the flow by splitting into two.
