Watercooling a GTX 770

[Ghost]

I made one of these threads for the GTX 780 and it turned out to be quite popular so this is one for the GTX 770.

Most of it will be the same as the info in the GTX 780 thread because of the fact they are almost the same card in terms of water-cooling but it does have slightly lower TDP.

Let me start off by saying when water-cooling a component the most important thing is TDP of the Graphics Card.


All credits for the table go to anandtech.com

As you can see the TDP of the GTX 770 is 230W, which is higher than the GTX 680 (195W) and lower than the GTX 780 (250W).

TDP is short for "Thermal Design Power" and is the cooling capacity (How many watts of power the component needs dissipated from it at maximum load). In a loop all the power is dissipated by the radiators.

Do not ask how many watts of power # radiator can give out, that is not the point of this. There are too many variables such as pump and fan speed. There is no clearly defined value and that is why most radiators are not marketed by how much power they can dissipate. You can have a look at the TDPs of various raditors at various fan speeds on specialist watercooling sites such as martinsliquidlab.org but don't expect your specific radiator with you specifc fans to be there.

I can try to quantify the number of radiators you need. Please bear in mind this is no way a final say on this topic. Other people may have other opinions on this and I welcome those opinions.

For a single GPU set-up:

120*120*# Would not be recommended.

240*120*30 radiator at medium fan speeds. This is the lowest I would ever recommend.
240*120*45 radiator at low fan speeds. This is what you should be aiming at when water cooling this card.
240*120*60 radiator at low fan speeds. This is more than enough for the GPU. You will not be limited much by temperatures any more.

140*140*60 radiator at high fan speeds. This would be cutting it fine and you would need high fan speeds.
280*140*30 radiator at medium fan speeds. This would be fine for the card.
280*140*45 radiator with medium fan speeds. This would be perfectly acceptable.
280*140*60 radiator with low fan speeds. I would say this is overkill for the card.

Please remember this does not include other things in your loop such as a CPU.

I have not changed any of the values from the GTX 780 thread because the difference in TDP is minimal. You can expect to run your fans ~100RPM slower with the GTX 770 than cooling the GTX 780

For a dual GPU set-up this should be double, technically speaking. However, as far as my knowledge of combining GPUs and their power draw after goes; it is not a 2:1 ratio. More of a 1:1.5 ratio. So expect triple rads as recommendations.

GTX 770 Waterblocks

No water-blocks have been officially announced yet.

 

If you have any information about waterblocks please let me know by relying to this thread and I will add it here.

 

EDIT:

 

EK blocks announced HERE.

From my initial looks of the PCB, the layout seems to be similar to that of the Titan and 780, albeit the GPU is smaller.

The GTX 770 is just a GTX titan that went badly wrong during production. Its like Nvidia cut the crust of the titan and then decided to make a profit on the crust. Its still an amazing card but it is worse than the titan.

 

In terms of water-blocks I don't want to say anything yet because I don't want to mis-lead anyone if what I say is wrong.

It is a different core gk104 not gk110 on the titan pcb as far as I can tell.

Just read techradar's article, you are right. The GTX 770 is an upgraded GTX 680.

 

Here's the relevant part for anyone else intrested;

With the GTX Titan's GPU making its way into the top card of this new generation, it has chosen to shift down the same version of the GK104 GPU from the GTX 680 into the second tier GTX 770. Essentially, we're going to see performance which actually ought to exceed the GTX 680 from this new card.

 

Despite reports to the contrary this isn't simply a rebadged GTX 680, though it is mighty close. "We have learnt from bad examples in the past," says Berraondo. "So the obvious one is the 9800GTX+ to GTS 250 - none of these are direct rebrands of what's come before."

 

But Nvidia hasn't done anything to change the GPU, or any of the power components - as was the case with the change from GTX 480 to 580 - but it has introduced a brand new level of graphics memory to the mixing pot and more of it to boot. The GTX 770 will have a full 2GB of GDDR5 that's running at a headline-grabbing speed of 7Gbps. So yeah, it should easily outpace the GTX 680, and, according to Nvidia, it's either on par or better than a HD 7970 GHz edition.

Soon. :)

The 770 Lightning uses the GTX680 Lightning PCB, so that means you can use the 680 Lightning waterblocks with the 770 Lightning.

EK has Introduced GeForce GTX 770 Water Blocks

Asus just revealed their GTX 700 series Poseidon GPU. No word as to which model it is, but word on the street is it's a 770. Google it, it looks pretty bad-ass.

If its costs less than a GPU + Waterblock then yes. If it costs more than a GPU + Waterblock then no way.

 

I assumed it was a 780.

[TheDigitalRealm]

It was leaked earlier as being a 770, which makes sense, because manufacturers are doing a lot more with the 770 than the 780 at the moment. 

I guess we wont find out until early July.

[nazaric]

Probably a stupid question, but are the 680 waterblocks compatible with some reference 770s. I thought the design was slightly different?

 

I just tried looking up a zotac 770 (2gb) and it gives me 680 blocks as an option, but if I look up EVGA 770, I get 770 blocks.

I think you heard about GTX 680 blocks being compatible the GTX 760.

As far as I know the GTX 770/780/Titan blocks are compatible.

There should be a forum thread with a list of all graphic cards and information if it is the standard PCB-layout or not. If not, we could add information to blocks that have been fitted to non-reference-PCB-cards by users.

IMPORTANT!  Supports GTX 770 cards (NVidia reference design only). beware of

non-reference PCB GPU partners.

Sorry for the stupid question, but I am new to watercooling. How exactly do I figure out if my card uses a reference pcb? I have the MSI TF 770, and I am trying to plan out and learn water cooling, but I cannot find anywhere that will tell me if the xspc waterblock fits my card.

Not a stupid question. http://static.squarespace.com/static/51998404e4b0ef02d1bd9c2c/t/520f4983e4b084c2cea82e4a/1376733571181/770.pdf

 

If it isn't there go to www.coolingconfigurator.com . If the "standard" EK block fits the card then it's reference.

[TheChucklingAtom]

Well crap, I guess I bought the wrong card. looks like ill have to get some different ones. Thanks for the info.

It'll probably cost less. But who knows. It's rog. We might be paying a premium
