Custom loop layout question

Go to solution Solved by DirkW,

Let's put it that way: you should only ever connect identical blocks in parallel. So 2-4 GPUs (with the same block): fine. Completely separate loop or the parallel GPUs put in serial with the CPU in one loop: both ok. But GPU with CPU in parallel... just don't. Water will follow the path of least resistance, resulting in one of the (very different) blocks not getting enough flow. So, OP, no U-turn from CPU back through the GPUs other side.

Hi

I am wanting to set my custom loop up so that the tubing goes from the pump to the gpu to the cpu then back to the gpu. Basically doing a U turn in the cpu.

Is this possible?

Thanks

If you trying to run them in parallel, you will damage either component. Gpu blocks have higher restriction than cpu blocks. Your gpu will likely over heat.

Yeah, it needs to be a loop, and if you are not going through the cpu into a pump/res and just abck to the gpu, you will effectively have no flow through the cpu, it would be both tubes flowing to the cpu.

I'm don't have sli at the moment but I'm sure I have seen this done before with sli set ups. My loop would be:

Res-pump-gpu-cpu-gpu-rad-rad-res. It would be a full loop just retuning from the cpu back to the gpu and then onto the rads.

It is simply for authentic reasons.

My main worry was the flow to the gpu, as I could see it just being bypassed.

Does your GPU block has 4 inlets?

How are you going to deal with to diferent flows or your block has a separate vrm dedicated block zone?

The block has four ports, two top two bottom like normal. I was going to use the bottom right as inlet from the pump, top right as outlet to the cpu block, top left as inlet from the cpu block and then bottom left as outlet to the rads.

What kind of block is that?

Isint the most inlets if you open top right and bottom right it will be a hole?

It's the evga hydrocopper. I'm not sure if it will work but I have seen it done before, snef has done it a few times with his gpu loops, going strait from one gpu to the next then back again to the rest of the loop.

For this to work you need to SLI it..You said you didint have SLI so its imposible(?)

How does sli effect how the water flows through the loop? I don't see how it would make any difference.

Because you cant implement 2 water sources in one gpu by how you said.If you have your gpu unscrew the holes and you'll see that when you open up two above its a hole.That why when you cool 2x gpus oposite inlets are used

Basicaly this what will happen

1.Is when it comes from the res/pump

2.After the U turn

Yeah I see what you mean. Wouldn't the exact same happen in sli, when I have seen it all four ports are used on both gpus, so wouldn't the flow bypass both gpus?

Thanks for all your help though. I will have to give it a good rethink.

Look at the gpus , you will see that the oposite inlets are used

Yeah I understand that but I have seen it where they are all used. It was a gpu only loop so went into gpu 2 from the bottom, to gpu 1, back to gpu 2 then back to the loop.

I think that thoose are diferent blocks:

Or they're dual layered so they have to layers where the fluid goes

Or they have a separated VRAM side

This is interesting as I didn't think their was waterblocks like that.

I know it seems silly but I'm really interested in trying this, do you think it would cause any instant damage? I was thinking of tubing it all up, getting the pump running then booting into the bios to see the temps. I know in theory it won't work but if I sit in bios and see the temp rise I can shut it off.

Actualy i dont know blocks like that too but i really dont understand how it works and thats the only explanation i thought of.I drew some schamatics but in every option i get fluid collision atleast once.

OFC you can try it.The most fun is experimenting.You can even mount the blocks to the rez out of the system and see if it makes any fluid colide or smth so you can test the flow and if it does smthin to the pump.When the flow is all good put it on the gpu and go test it again

These are running in parallel is all. All the ports on the left hand side of the card would be inlet, all the ports on the right would be outlet. Just read up a bit from EK or one of the other water block manufacturers about Parallel vs Serial flow.

Correct. Just a parallel loop. Nothing special about the blocks at all.

It looks like the skunkworks build by Jayztwocents on youtube. If you wanted to see how he built it, you could just look it up. As the rest already said, just a parallel loop config.

In general, you probably don't want heated water to flow back through another component that you need to cool off.

But the water equalizes throughout the loop does it not? I know some spots would be a degree or two hotter but the water in the rad is still part of the same body of water going through the gpu and cpu. I may be wrong, I've done a lot of research since I'm about to do my first custom loop but I may have misinterpreted something.

There is a difference between running Paralell GPUs, and then running parallel gpus+parallel CPU. 

 

The latter will just not work, because you will not have much of a flow at all. Direction of clow will be confused.
