Would it be possible to solely water-cool 2 GPU's + is it worth it?

    Hey guys,

    So I recently upgraded my PC and grabbed a pair of GTX780Ti's. I have been seriously contemplating having them water-cooled as I'd like to over-clock them.

    My main question was, is it possible to have water cooling solely for the GPU's, and if so, is it worth it?

    I had heard somewhere that you could use a H80i to water-cool a GPU, but i don't know if this is true? If not, what would you need for a custom water-cooled setup?

    Thanks :)

    EDIT: I should note that I already have a h100i for my CPU and my case is the Phantom 820 full tower gaming case.

    There are adapters that allow you to mount CPU all in ones on some video cards. But full coverage water blocks with a custom loop is the best way to go.

    Is it possible? Yes

    Is it worth it? IMHO No.

    I have the same card as you do, and I just don't see the need to WC it. The ACX cooler does a very good job. My card has yet to see above 74'c, even when boosting to 1274 MHz running furmark.

    I really should update my system specs. I actually had 2 Evga 780Ti's, but one was faulty and the store I bought it from had run out of stock. So I actually ended up with one Evga 780ti and a Palit 780Ti Jet stream, which I am yet to receive.

    I recommend a full custom loop. You can exclude the CPU, and get two full cover blocks for the GPU's. A 360 rad and res/pump will do the job fine. I do not recommend using AIO (H80, H100, Kraken X40, Kuhler 920) watercoolers designed for CPU's to be mounted to your GPU's. VRM and memory cooling is important, and full cover waterblocks in a custom loop are far safer and superior.

    Oh right, glad I didn't go for that option then. How much would you expect a full custom loop minus the CPU to cost?

    GPU blocks are pretty expensive, probably the most expensive part in the build. Not sure what currency you use or where you can buy W/C kits from.

    I'm in Western Australia so everything is pretty expensive. The store which I find is the cheapest is www.ple.com.au

    I have no experience with custom loops so I wouldn't know what is required.

    They seem to sell these kits, but I don't think they include GPU cooling. - https://www.ple.com.au/ViewCategory.aspx?CategoryId=691

    You will need:
    2 x Full cover GPU block (one designed for EVGA, one designed for the jetstream)
    1 x Pump
    1 x Reservoir OR a pump/res combo unit (Raystorm 750 e.g.)
    1 x 2 meters 7/16" tubing or 1/2" tubing
    8 x 7/16" or 1/2" compression fittings(depending on what tubing you buy)
    ^ you may only need 6 of these if you buy a pump/res combo ^
    1 x 1-2 litre bottle of distilled water
    1 x 360mm Radiator

    4 x 1/4" plugs for your waterblocks if they don't come with any.

    wow gusy slow down a bit.
    before shopping you have to check what water blocks fit your cards pcb design if there is such waterblocks.
    both of your cards are non ref and it is possible thier pcbs to be differ from reference design. normally vga waterblocks are desinged for referene pcb.
    check your sku numbers of your cards and check http://www.coolingconfigurator.com/ if and what watter blocks can fit on your cards.
    if your card can fit wb for reference card then its pcb is reference and you can use any waterblock for ref cards.

    Im with Rcoon on this one, avoid the modded cpu block kits, go fully custom and one day you can add in CPU, more rad etc.

    A loop is for life not just for christmas.

    Plus your cards under water will bench/OC far greater than on air, you should also join our hbwot team once done. :D

    @d1nky , @the54thvoid and @radrok can probably help you out more on this than I can, I've been out of the watercooling game for a few months now.

    You need the Ti versions of the waterblocks. Check the compatibility of the water blocks with the 780ti's before you consider it.

    Reference 780's and 780ti's use different waterblocks, as proved here:
    http://news.softpedia.com/news/EK-F...k-with-GTX-780-Ti-New-One-Coming-398355.shtml

    Here are compatible waterblocks for the Jetstream 780ti

    Use this for compatible waterblocks for the SC ACX 780ti

    I cant remember what metals you shouldnt mix in a loop, or whether it doesnt matter.

    Acetal, copper and nickel? is that rad brass as well?

    Ive forgotten so much...:confused:

    Don't mix copper and alluminium.

    Lots of good advice and I have nothing to add!

    but....

    The greatest piece of advice for a custom kit is plan it before you buy it. Plain fittings are great and all but sometimes it is far better to get a very good picture (literally) of your loop design and plan the fittings around it. You can get angled fittings and rotary fittings which help a great deal to avoid tubing getting distorted. They cost more but ultimately make a loop easier to instal and prevent fittings loosening through time as coiled tubing 'unscrews' them from rads etc.

    Follow what RCoon has said about the cooling configurator from EK - nothing worse than someone trying to force the wrong block on a card - you will break it.

    Also, I think you'll need 10 fittings, not 8.

    Pump (fitting) tubing (fitting) rad (fitting) tubing (fitting) block (fitting) tubing (fitting) 2nd block (fitting) tubing (fitting) reservoir (fitting) tubing (fitting) - - - - - - back to pump. Someone correct me if i'm off o_O

    You are correct, 10 fittings if you buy a seperate reservoir and pump, or 8 fittings for a pump/res combo.

    THe EVGA GTX780Ti SC ACX does use the reference PCB its just got a small OC with a ACX cooler slapped onto it.

    You will need a waterblock like mine which is a EK-FC780 GTX Ti - Acetal+Nickel.

    GTX 780 TI waterblocks can be used on titans and 780s but not the other way around as they updated the layout on the TI so its not 100% the same.

    ok but better verify it with someone that makes whaterblocks then to look at contradictory info in interwebs

    Compatibility list for EK-FC780 GTX Ti - Acetal+Nickel I have already brought the block just haven't installed it onto my card yet still waiting on my res to come though the mail, But all evga cards apart from the classified use the reference PCBs.


    Also read down on TPU review and you will find

    EVGA 780ti SC ACX is a reference board as @Live OR Die says. The Palit Jetstream might be a pain in the ass though.

    Yer i don't think there are any blocks out for the Palit Jetstream at the moment and seeing he lives in Australia like me 780 TI full cover blocks seem to be selling like hot cakes.
