So I have a question for someone who knows a lot about water cooling. It's about adding a waterblock for my GPU to a not yet bought complete water cooling system for my CPU.

Here's a pic of what I imagined:

If anyone has any suggestions to what I should change/not change it's much appriciated.
I'm planning to buy these:

Corsair Hydro H100i
(Full water cooling system for my CPU, will this be to "weak" to cool a GPU aswell?)

EK Waterblocks EK-FC R9-290X Acetal
(For the Radeon R9 290 (not the 290X, it fits for both)

If anyone has any thought please say them.
Thanks! :)

1. Yes the pump in the H100i will be too weak for that loop. Also since the pump is located in the CPU block itself you would have to have another pump anyway directly under the reservoir like in your picture. I recommend just getting a pump and a CPU block. Sell your H100i and use the funds from that to get a proper radiator, pump, and CPU block.

2. You don't need that T-splitter coming off of the pump. Have the pump go to the GPU block, then come off of the GPU block and go into the CPU block, then to the top radiator, then return to the reservoir. Having two T fittings requires a lot more pump power and consequently will drastically reduce flow unless you have something like dual D5's or a dual DDC setup. There's no need for all of that. Just go Res > Pump > Block > Block > Rad > Res.

...you realize you can't take apart the H100i and add more to it, right? That's why it's called a "closed loop" liquid cooler. It doesn't even use water, and the pump it has is unreliable, wimpy, and loud. Also, why would you use that when your image shows you having a separate pump?

I highly, HIGHLY suggest you get something like a Swiftech Apogee Drive II, run its line in from the res, its line out to the GPU block, and then run that to your radiators. That way you don't have this awful T-line that's going to cause issues, you have a simpler run, and a way better thought out system.

Also, you do realize that the radiator from the H100i is awful and barely cools an overclocked CPU, right? For a CPU and a GPU, you're going to want a triple 120mm at the very least, but more likely two doubles, considering how bloody hot AMD's new cards run.

This is what I've been working on. I use more rad space than necessary. But for one CPU and one GPU I would recommend at least 360mm of radiator space. My general rule of thumb is 120mm of rad space PER cooling block plus 120mm for good measure.

Ok thanks guys, the only problem is that my budget is kind of limited :/ I don't know if I can afford to buy all the part separately. And also, I had the T-splitters so that the water would not have to go through them both before getting cooled again, but if you say that the pump can handle that I guess I'll buy a better one and every piece for themselves and probably save a little more money before buying anything at all so that I can afford some better stuff.

What type of budget are we talking here and what case is this going in? Also what CPU and GPU are we trying to cool?

EDIT: I see the 290X block, that's a great block and has no trouble cooling the 290X/290. I cool my 290 with a Koolance 290X block.

Well, honestly my budget is kinda unknown at the moment, it depends on what other stuff I'm going to buy, I need a motherboard and some RAM aswell.

The Case: Cooler Master Stryker White
The CPU: Intel core i5 4670K
The GPU: Radeon R9 290

But about how much will this cost if I want a proper watercooling system for these two? I don't need an overkill watercooling system, just one that works fine. Also I was not planning on overclocking neither of them, I don't really know anything about that stuff but I might want to do some OC one day and then I want to be able too. I'm simply buying this now because I heard that the R9 290 cooler sucks and that it will become so much better if it is watercooled.

Wait... you aren't going to be overclocking and you want a full watercooling setup?

The 290 cooler DOES suck, and watercooling it removes the thermal limitations, but it also gives you overclocking headroom. You'd be wasting a lot of money if you didn't overclock your CPU and GPU with a setup like that.

You'd need about a $375 to cool all that the right way. There's cheaper ways of course but I wouldn't recommend it. This kit is sweet, $260, add your $100 GPU block, 2 more fittings for the GPU for $8. You would be wise to get a biocide and/or corrosion inhibitor, I recommend the Mayhem's X1 Coolant.

Kit: http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=59_202_972&products_id=39812
Fittings: http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=59_346_951&products_id=30114
Coolant: http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=59_381_1071_915&products_id=34058

And you're good to go.

Unfortunately the case you want wont take a 360mm rad up top. You could always get the 240mm version of that kit but I would recommend getting another 120mm rad and putting it somewhere in the loop. It will cost more though.

Grand total of the parts mentioned above and your EK 290x block is ~$400 from Performance-PCs.com
