Turning a Swiftech H240-X into open loop, first time water cooling.

Hello,

I'm in the process of doing some renovations/rebuilding as my old Gigabyte mobo recently died.
I have purchased a ASRock Z77 Extreme 6 mobo which I will transplant my i7 3770K to. I also bought a new case (Phantek Enthoo Luxe) and PSU (EVGA SuperNova 1000W P2).

In my old case I cooled my CPU and GPUs with air (Hyper 212 EVO in the case of CPU). This time around I want to purchase the Swiftech H240-X, adapter for pump (sold out at the moment) and some clear tubing (bigger bore diameter better or worse?) which I want to fill with some non conductive (does it matter?) blue coolant.

Right now I will be transferring my two EVGA GTX 670 2GB FTW cards and keep the H240-X as a CPU only AIO cooler.

Down the road, however, when the GTX 980 8GB variant is released, I intend to purchase one and use that as my primary card for some time, perhaps SLI down the road when it can no longer max out whatever I throw at it.

Questions:

1.) Do I need an additional pump, res or radiator if I decide to add a single 980 into the mix? I've seen people with multiple pumps and rads for a single GPU/CPU setup with the H240-X but I've also seen people just run the out hose on the CPU block to the GPU block and then from the GPU right back into the radiator. I want optimal, quiet cooling and a slight bit of overclocking but I'd rather not drop too much money and spend extra time setting up additional components if it is unwarranted.

2.) Also, I don't entirely understand the process of bleeding/filling the loop. It looks like the fill port location on the H240-X would require me to remove the unit from the case in order to fill it if I extend the loop. Would I need to remove the CPU block then as well and then reinstall/reapply thermal paste etc.? Should the loop be fill outside of the case?

3.) Lastly (somewhat related to question one), if I did SLI GTX 980s down the road (dual SLI at the most), would the single reservoir, pump and radiator be enough to cool all components without adding additional parts? From what I've read the H240-X has a fairly powerful pump.

Semi related: Looking at EVGA's GTX line, the 980 4GB variant (Copper series) is like 700$ or so with a waterblock, and their stock 980s (not the classified) are around 500$ but the waterblock alone is 150$ (so ~650$, might as well get the Copper). I love EVGA but I suspect that when a 8GB variant of the 980 comes out it will be quite expensive from EVGA, as not only are the 980s already faster than the Titans, but the 8GB vram will make them some of the most powerful, capable cards out there.

Any disadvantage to buying a regular old 980 8GB from nVidia (when released) or a different aftermarket vendor and then adding a cheaper aftermarket waterblock? The cherry picked and pre-overclocked cards are nice, but I'd rather have something stock, and be able to put a 75$ copper block on it than pay a grand (a total personal guestimate at what an EVGA 980 8GB Copper card will cost).

Thanks.

I would not get a 8GB 980. if you are playing at 1080p, 4GB is going to be enough for a long time. 2GB is starting to be too little. I understand your worry, but the price that you will be paying is not going to reflect in the performance. However, I am not going to try and stop you from purchasing the 8gb model. If you do decide to go eith 8GB of VRAM, I would personally get the 970 as you would save a lot of money and not loose that much in terms of performance. 2 970's right now are only $100 more than a single 980, so I would imagine the price difference in the 8gb models to be the same.

Anyways, the order of the loop in your case does not matter. Whichever allows the cleanest and shortest runs is best. I would make the loop like...
If you add a 980, getting another ad otherwise your temps will not worth the price you are paying. The pump is enough for another GPU and rad so don't worry about that. If you get dual GPU's. Make sur eyou don't get a poor waterblock. EK has some good ones along with swiftech. I would add another 240mm rad to the loop if possible. Don't get coolan't as they will clog up eventually and can cause issues. Distilled water and colored tubing is the best way to go. If you want a dye or coolant, Mayhems pastel coolants and dyes are not horrible. For bleeding and filling, its best to watch videos for that. I believe Jayztwocents has a video on that where he bleeds his own loop (it might be in the first skunkworks video).


Also, why in the world do you want an 8GB 980?

Thanks for the response. I'm sure I could fit another rad in the front of the case. How would the loop be setup then?
Swiftech >cpu block>2nd rad>gpu block(s)>swiftech?
And the reason I'm going for the 8gb 980 is because when I bought my 670s I was told "2 gb will be fine for years don't worry" so I got those instead of the 4 gb models and I've had plenty of maxed games stutter due to vram. 8 gb should let me run those cards in dual sli for years. The ongoing trend of shitty console ports has me thinking better safe than sorry.

Swiftech>CPU>GPU>second rad> swiftech as its cleaner to go from CPU to GPU in most cases. The order of the loop doesn't matter except when you have a separate reservoir and pump. The water moves so fast that the warmest and coolest points in the water are less than a degree in temperature sway from each other.
