Pass Through GPU liquid cooling

[DanielOz]

I like the look of the attached setup and want to do something similar.

 

My question is is there consequences to having the liquid pass through both sides of the in and out on the way to the cpu?

 

Does this basically create a half flow scenario for both?

Can it be worse than that?

Do all GPU coolers work well in this setup?

 

Using a Phanteks Glacier 1080 ti GPU cooler and a EKWB M9H Water block.

 

I imagine this matters because of the back pressure of each device ultimately controls the amount of fluid that flows?

Maybe none of this matters because liquid flow rate isn't that important?

I´m not sure I understand what you mean here, but to me it looks like it´s just one in loop and one out, don´t see any issue at all.

Tho, I´m not a fully fledges expert on custom loops ^^

I think that even though technically you would never do this type of cooling setup on something important like a car or irrigation system due to the dead spots it creates , I think pc parts are small enough and the pumps are fast enough that it doesn't matter.

but yeah in a larger type of pluming system you'd never want something with dead spots like this.

welcome to the Linus Tech Tips forums!

 

that flow pattern is called parallel flow. like air, liquid will take the path of least resistance and if there is greater resistance in the GPU block, the flow through the GPU block will be substandard. many have/still use parallel than series and report no real ill side-effects. ive used parallel flow systems before, but always revert back to series.

I’m using a parallel loop right now, looks nice and performs the same as serial (I usually have a d5 or dual ddc)

Doesn't perform any different. Only issue I found I had was certain fittings covered the flow. 

 

Loved the look and simplicity of it. Ran 3 blocks in parallel, no issues as there really can't be any.

It will run fine like that,Jayztwocents did a build like that
