Liquid cooling for both CPU and GPU on one radiator?

Hello,
is there a chance that I can find split liquid cooling for CPU and GPU together. I don't want to put two separate radiators. Is there something like splitter or by adding extra pump to it.. Someone did/heared something like this?

Thanks,
S@
 
You can run everything in serial, no need for multiple loops. If you absolutely insist, two y-splitters, one before the CPU/GPU and one after, would do the trick. That's called running in parallel.

I ran two GPUs and one CPU, all in serial (meaning water went cpu -> gpu1 -> gpu2) on one radiator.
 
Do you have images of how it looks like? Can you point me to a certain example so I can get it visually.
Will one pump be enough for both? Will one radiator/cooler do the cooling for both? Will the pump stream the liquid all the way?

Thanks,
S@

Depends on the pump/rad and blocks chosen, you build to your need, depending on the cpu and gpu you are cooling will tell you about what size rad you need and you will pick a good pump that can push through all of it. You would have also been better off posting this in the watercooling section.

I'm planing to do micro gaming case in Thermaltek Armor A30 with ASUS Maximus V Gen and Ivy Bridge 3770K. The gpu on the start is 5870, but will be upgraded soon.

Logicaly when you do it serial, in your case, the gpu1 will get the hot fluid from cpu and gpu2 will get very hot liquid from both. Where is the actual cooling when you bring hot and 2x hot water to the gpus?

If you keep up a good flow rate, the water temperature rises at most 1 C from block to block. In my experience, gpu2 under load was only 1 C hotter than gpu1.

This has been discussed many times, and many watercooling guides cover it, if you bothered to look for them.
 
Yeah, I found one saying exactly the thing you said :D
Thanks!

Now you seed keep good flow rate. This is up to the pump only or...?
 
It is up to the pumps and the blocks you use, and how many of them. Some blocks are low restricting blocks, so they don't cut down on the flow rates as much. Some blocks have higher restriction, so flow rate is cut down more. Obviously more blocks/radiators cut into flow rates.

You can have one pump, or several pumps. More pumps in serial increases the maximum head pressure, cutting down on flow rate losses due to restriction.

Having blocks in serial increases overall restriction. Having blocks in parallel decreases overall restriction, but divides the flow rate by however many blocks you have in each block in the parallel section.
