Inspired by Pako's purchase of 780's (which I was going to buy anyway), i've thought a bit about water cooling them.

Thing is, i've never been even remotely close to mount or even watch someone mount watercooling system for GPU's. And youtube is kinda random.

Does anyone have a part's list required to watercool 2 x EVGA 780's Hydro Copper?
If I only have the card, and the waterblock mounted on the card, what else do I need?

I know I need tubes, waterpump and stuff, but an exact list for the 780's would be nice.
 




He's using Titan's, but as 780s are basically Titans, this applies to the 780s as well. It gives you a rough idea :)

Yeah, well i'm kinda looking for a list of the parts needed. When I get all the parts needed, then i'll look on some tutorials on how to mount it all together, or get help from a friend who knows.

But those videos will definitely help later on. Thanks.
 
I will throw something else at you. If you're making a loop for the gpu(s), you might also consider putting the CPU on water also. In fact, you might get more benefit from that than what you will get from the gpu(s).

I will ask, how many 780s and do you want to include the processor also? If yes, what processor? What case and PSU do you have?

I already have watercooling on the CPU, Corsair H80.

I guess 2 x 780's is what I am aiming for.

Case is HAF X Big Tower and I got 950W PSU.
 
There might be some closed systems like your H80 designed for the 780's. If not, a custom solution is in your future.

A basic parts list for a custom water loop would include:

Water Blocks for the Cards
EK makes some nice ones. Consider a full block with back plate.

Pump
Check out Swiftech's lineup. A single inline pump will do ya.

Radiator and Fans
I would suggest a 360 rad for the two cards. x6 120 fans in a push/pull configuration will give you optimum cooling.

Reservoir
Lots to choose from here. Consider where you will be putting it when you pick your res.

Tubing
I would look at 1/2ID (3/4 OD) tubing. Lots of colors to choose from here. I've always done clear with colored cooling liquid. You could go 3/8"ID (5/8"OD) if you like, not a lot of flow advantage in your case, but I find that the larger tubing is less apt to kink on tighter bends. Takes a bit more planning, however, when routing your tubes.

Fittings
I would highly suggest compression fittings. Maybe even a few quick disconnects. Different brands here to pick from. Koolance has been pretty good for me this last time around. You want to stay away from tight bends in your tubing as well as staying away from 90 deg fittings as much as possible. Go with 45 deg fittings when you can.

Liquid
Check out Feser cooling products. Lots to choose from here.

I've purchased most of my parts from: www.sidewindercomputers.com

^ Oh snap, that's a confusing list. :D


I'll check and see if there is any norwegian sites selling the parts needed.
 
EVGA have offered the hydro copper on the high end single core cards for a while now.
Getting a EVGA GTX780 Hydo copper will be harder than winning the lotto.
 
Well, might as well take a reference 780, put a less restrictive water block than the EVGA blocks, and flash the bios to the Hydro Copper Bios and call it day....save a few bucks along the way to. :)
 
I don't know.... There are some pretty sexy blocks out there. You can even get the EVGA ones by swifttech if you like.
 
It's also the limited edition bragging rights you get on PC Hardware forums.

As it is very hard to get a hydro copper card as is.

And adding a waterblock may void warranty.

I got a notice a couple days ago that EVGA had hydros in stock. Better jump on those bragging rights. :lol:
 
I has no monies, you can donate to fox if you choose..

Plus my GTX680 is still got the power to run games at full settings and still give a good frame rate.

Looking into a waterblock for it for some time.
Just seeing if it will affect my warranty in anyway.
 
Im taking up my own donations. ;)

What brand is your 680? Usually it will not. Bios flashing and volt mods will, however.

Waterblocks will not effect your warranty. Just make sure to keep all your original cooler parts and screws so you can put it back to OEM if you have to RMA it. Physical damage is not covered, so take care when installing the block, etc.

Quick question, do I need to re-install windows when changing graphics cards?

ATI to Nvidia!

Nope, just remove the ATI drivers and software and install the nVidia.


Does anyone know anything about the Accelero Hybrid? It looks like a nice piece of kit.

Looks like a simple kit. Would probably be fine for a single card. I think that things would get a bit tight in an SLI configuration. I would be curious of the performance. Probably fine for the GPU but I see little thermal treatment for the vram modules or the voltage regulators. Have you found any performance benches on this?
 
Found this.

It actually doesn't look all that simple!

*edit*
It looks like you have to use thermal adhesive for the vram and voltage regulators. Not ideal but fine if you will never open it up again.

Here is something to be aware of:
One dislike, the VRM and memory heatsinks will need to be secured with a thermal adhesive... in normal wording that means you glue them to the ICs and that is something you need to be VERY aware of. You will not be able to remove the heasinks afterwards.

Performance wise, at least on that ATI reference card, looks very good and should provide some great temps allowing for the max overclock that the chip will allow.
