Gpu loop

[georgon]

I want to create a loop only for the gpus.

Which version should I choose?(attached image)

What are the pros and cons of each case?

Don't know about the technical specifics, but if you go with the second one I think the difficulty of the build would go up?

No pros nor cons other than the second loop is ugly and more difficult to execute. Both GPU's will get the same temperature water and flow in either configuration.

yeah cable management and fitting components in the motherboard would be a nightmare in the second build...

1, without a doubt.

Thnks, good to know!  I'll post an image as soon as I set it up.

@ me when you do. I'd like to see it!

Installed blocks and radiator yesterday, only the tubes remain.

Reading the instructions of aqua graphics blocks, it says use only in serial which seems weird to me.Does it mean theyre not gonna work in parallel or is it just a suggestion?

Anyways seeing the loop which tubes connections whould u suggest?

I’m pretty sure they offer blocks for mounting two cars together. So look that up and see what it is. A serial or parallel block. 

 

The will still be the same but just halving the flow. So give it a try or read up on their options.

You will want something like this to connect multiple GPU's:

They prefer serial over parallel because parallel does a few things: 1. Makes unnecessary connections. 2. Reduces flow to each component. obviously, flow should be more important than water temperature as the water temp in either configuration is negligible.

 

either way, looks good!

Which ever one looks better.

When it comes ot PC loops, it really doesnt matter.

 

Which ever you think looks best go with.

 

There is a bunch of theory behind which is best and it total depends on the siuation. Such as amount of restriction, total possible flow, and pressure etc etc.

With little or no restriction in each block, seriel wins as theres no reason to split flow. But with restriction is present, you have to work out whether spliting flwo between the blocks is a benefit over parallel were 1 block can restrict enough to lower overall loop flow rate vs splitting the flow at the blocks allowing for higher system flow.

For example

 

Seriel (3 = unrestricted flow)

3-1-1-1=1-

 

Parallel (3 = unrestricted flow)

  -1-

3-1=3-

  -1-

 

But like i siad, blocks,rads, and pumps in PC loops today result in little to no difference, so go with what ever you think looks best.

Looking at the build itself, the second option would not be harder than the first to do, but as JayzTwoCents always says and has proved, the order doesn't matter. Logically, you would think that the first one wouldn't work because the heated up fluid from the first GPU would be heating up the second (in the direction of the loop). But actually, the fluid's moving so fast that it all heats up at the same pace and cools everything equally. Things can be in ANY order in the loop with virtually no drawbacks, all except for the reservoir. It must be feeding directly into the pump, but that's no problem since yours is a pump/res combo! Either way works.

[georgon]

Added another 240 radiator in the front and moved the 360 on top.

Moved the pump higher so its in line with the cpu block inlet.

Moved one of the gpus a slot lower to make room for the fittings.(crossfire runs@x8 but the performance difference is negligible plus the cards run cooler).

Idle 28C for cpu/gpus, load 45 with all the fans @900rpm, pump 40%

I'm pretty satisfied with the final result, given the space of the define s. For future watercooled builds though, I would consider getting a bigger case.

Thank you guys for the feedback!
