Ok, so I purchased the Aorus 1080ti AIO variant a few months back and then decided to build a full custom water loop.

I have the GIGABYTE AORUS Xtreme GeForce GTX 1080 Ti Waterforce 11GD, GV-N108TAORUSXW-11GD ( ) and bought the corresponding EK FC1080 ti Aorus( ) which was described as compatible on the EK website.

Unfortunately, this is not the case. I have included the picture below that shows the difference. The center screw hole is shifted over about 1/4" - 1/2" and does not fit.

After some more research I found that my card has the same VRM layout as some of the other Gigabyte 1080 Extreme cards ( the non-TI editions) like so:

I stumbled across this Youtube ( ) and noticed his card has the same VRM as mine and the GPU waterblock he was using does not have that center screw stud to interfere with the different VRM layouts.

Here are the two GPU waterblocks from China that should be compatible with my card. These waterblocks also cool the VRM modules that Gigabyte decided to cool but EK left out for some reason confused.gif . I will update this post after I order one and let yall know. I know this will only be useful for a small subset of people that are in the same situation as I am in but hopefully it helps someone!



model: n-gv1080xt-x
(Can't find the OEMs website haha)

Sorry for the inconvenience!

Both Barrow and Byksi don't have the center standoff which is causing the incompatibility issue with the EK block.
If you are comfortable with that, can you please try and remove the center standoff and check will the block work
on the GPU that you have?

Since the design of the card is changing here and then, we are still looking into all of the PCB variations on the market.

EK is working on a water block that will be compatible with all new versions, and reverse compatible with older PCB layouts.
If you don't feel OK fiddling with the standoff, we will just ship you a new block once we have it ready.

DrZotro - I'm in the same situation you were in. I'm trying to integrate my 1080ti AIO variant into a full custom loop.
I noticed a difference in the FET (?) layout between the AIO variant, the WB variant and the aircooled one. Both the WB and the aircooled ones have the same layout, but, there is a 5th row of FETs (again, I think they are FETs) that seem to be SMD'd on the rear of the card for the AIO variant, but front side (die side) for the air cooled and WB versions. The EK WB seems to be compatible with the aircooled/ WB versions.
I haven't personally taken apart the card. I've only compared tear-down videos/ images of others.

Anyway, did you find a compatible block for the AIO variant?

Hi Atila,
I too have the 1080ti AIO version of the card. I was wondering if this is still compatible - I am okay not installing the centre standoff.
Would the rest of the board be okay? There also seems to be a row of FETs (towards the VR port) which seems to be SMD'd onto the same side as the die on EK's photo, but on the opposite side on DrZotro's photo. Any concern about this?
Any input would be helpful
