Adding GPU to water loop

[matt198992]

For reference, I'm using one of the DIY kits from Frozen CPU that I plan on modifying, found here:
http://www.frozencpu.com/products/20926/ex-wat-266/XSPC_Raystorm_750_EX280_Universal_CPU_Water_Cooling_Kit_New_Rev_4_Pump_Included_w_Free_Dead-Water.html?tl=g30c321s1310

Ok, so I've just gotten into the watercooling biz about a year or two ago and have worked with the DIY kit above (which was amazing!). I've since messed around with it a couple times and have switched from collant to distilled water. Drained the loop a couple of times, but never really MODIFIED it before. It's currently just running to my CPU and nothing else in my rig.

Now, I'm looking at upgrading my GPU and what better time to incorporate that into my loop? I'm also planning on adding a valve/drain to the loop (which I should have done at the start) so I can take it apart next time without getting water everywhere. So I'm essentially making two mods to the setup and I had a couple of questions for the experts that I can't really find solid answers to online.

1) Should I add a 3-way splitter to the line just after the pump, essentially splitting the line into two in order to reach the CPU and GPU at the same temp, then rejoin with another 3-way splitter before the radiator? Will that work, or will the pressure be too low and can my pump handle that? Or maybe I should just forget the idea and have the line run to the CPU, then the GPU, then the rad, then back to the pump/reservoir?

2) Can my pump handle the addition of the GPU to the loop? I'm using a pretty big radiator with good fans keeping it cool, so I hope the rad won't be an issue either.

3) I'm pretty sure I know how to add the drain, but wanted to double check. I'm basically going to add a 3 way splitter at the lowest point of my loop and attach a ball-valve for easy drain, yes?

Sorry for the wall of text. If you need more info, let me know. I can attach a diagram of my theorized loop if needed too. Thanks in advance!

1) No, just let the water flow to the CPU after GPU (does't make any difference if its reversed) , RADIATOR and do again the bucle.
I would do
PUMP -> GPU -> CPU -> RADIATOR -> RESERVOIR -> PUMP

2) Which radiator do you have?

3) Yes.

The pump will be able to push the water through all of the loop.

At the lowest point of the computer is where I would put the valve for the drain.

After the pump You can place a Y splitter.

The radiator should handle the CPU and GPU but if you want better temps, then I would get another radiator.

The loop order I would go is Reservoir, pump, radiator, GPU, CPU, reservoir.

Sorry, I didn't make that clear. I have the radiator listed in the link that came with the DIY kit. I did not buy a different one.

I figured to keep the water as cool as possible with the splitter before hitting the two core components. Thought it would transfer heat a bit better.

Oh no, i apologies, bad typo, i wanted to ask which pump do you have.

No worries! I also have the same pump/reservoir that came with the kit in the link above. I have all the same hardware from that kit.

You're safe. Just buy the block(s) and put it in your loop.

Outside of the thread, which GPU/CPU are you going to cool? (Just curious!)

I have the AMD FX8360 that I'm CURRENTLY cooling and it's worked well (though, even after the adition of the watercooling I have not been able to overclock it reliably even a little bit, which is a bummer), and now I'm going to be adding the GTX1080 Seahawk EK X which comes with a built-in waterblock. I'm pretty excited to order it, and just wanted to double check everything.

It seems like even with a Y-splitter, my rig should have enough pressure for the addition of another line. It will be tight in my case, but it will do until I build my next computer case.

Are you goint to play @ 1440p or higher resolution?

Not quite yet. Don't have the monitor for it. But I plan on it soon. Don't tell me I'm better off getting a different card, haha! I'd rather have a card that will last me than have to upgrade in the near future.
