Strange water cooling config... thoughts?

[Steve1978]

Hi, 

 

well lets just just start by saying I enjoy arsing around with my components more than I do actually using the computer..., I think that will hit home with a lot of readers! 

 

I have the the following components.. h100x aio 240. H100i v2 aio, thermaltake 240mm separates (45ltr pump, res and 240mm rad) so that’s 3 240mm rads, 2 blocks with pumps and a separate pump...

 

i am am looking for a little project and was considering splitting the h100i and adding a second 240mm rad, or maybe even using the 3 240mm rads almost in back to back formation with fans separating them? And then adding in the cpu and GPU in to the loop.

 

anyone have any thoughts on this?

 

will more rad space really make a difference? 

Do you hit a maximum where adding more rads makes no difference?

will the 400ltr ph pump push the lot, or should I use the block pumps on the aio systems too? 

 

Any my thoughts or ideas?

Sooner or later you will reach a point of diminished return.  When that happens, it won't matter what you do because whatever you do, it won't make any difference.

Yeah, I kind of thought that, I currently just run a Ryzen 2600@4ghz 50c full load, but I am thinking of making it a bit sexier!, maybe a nice reservoir, see through hose. Then maybe adding the 1080, 

 

do do I add 2 240mm rads to a single loop with both components or have 2 separate loops....

1 - pumps need run in tandem and need to be the same RPM if you are going to run multiple pumps

2 - If you use the AIO's pumps they need to all match RPM

3 - You can take the AIO blocks apart and took the pump mech out so it doesn't block flow to allow it to be a block

4 - Just make sure however many radiators you use they are not run parallel but in a series (one big circle, not splitting lines into multiple rads at the same time)\

5 - If you are using AIO radiators they are aluminum very very likely meaning you are mixing metals, use appropriate fluids to prevent galvanic corrosion

6 - the size of the reservoir will not impact the temps of the loop unless you buy one of those crazy radiator reservoirs

7 - Id run 1 large loop (I have done all this research recently, have all the parts now inc from China 2x240mm rad, 1x 120mm rad, 2x 80mm rad, pump, cpu block gpu block, res)

Interesting what you say about pump speeds, I can see how it would help having multiple pumps at the same speeds but IF you had differing speeds wouldn’t the additional pumps just help push the water round or would they actually slow the water down?

Im regurgitating what Ive been told by those much more wide and learned on custom loops than I after asking the same questions (and I have 2 pumps I wanted to use).  By definition however this is what happens when to much flow is allowed through a pump:

 

Air entrainment occurs when air is allowed to enter the pump on the suction side and expands as it enters the impeller eye. This can often reduce the flow of the pump and cause vibration from disrupting the laminar flow stream through the pump. Air entrainment can cause similar damage to bearings and seals.

 

I also spoke with someone who used AIO block/pumps in tandem with loop pumps and he said don't do this unless you can control the speeds to be the same RPM, if you cant then gut the AIO pump/block to its just a block as they are quality blocks.
