I just bought an ASUS KO RTX 3070 OC at Microcenter.
Why this one? It was the only one available!
Now, time to find a water-block for this puppy.
I did not take-off the air-cooler yet, but I have found this picture of the PCB online

This seems identical to the PCB of the ASUS GeForce RTX 3070 TUF Gaming OC

...but cannot be sure since the KO PCB picture is not complete.
I have to check it on my own, but first I hope to hear from others that may have done it already.

Considering these blocks:
- Corsair HYDRO X SERIES XG7 RGB RTX 3070/3080/3090 ASUS STRIX GRAPHICS CARD WATER BLOCK (CX-9020013-W)
- Bykski N-AS3070DUAL-X GPU Water Block for ASUS RTX 3070 DUAL + BackPlate aRGB
PLEASE, HELP!

May just need to take it apart and look. Quick glance they look similar. You can pull the heatsink off, snap a picture, reapply TIM to the die and put it back together until you decide on a block.

Thank you termite.
I ended-up buying a
Bykski 3070 GPU Water Cooling Block For ASUS RTX3070 DUAL, Graphics Card Liquid Cooler System, N-AS3070DUAL-X
from FormulaMod.
The pictures in the item description look promising, with a hypothetical overlap between the DUAL version and the KO one.

Fingers crossed!
I'll post pics once it arrives and it is mounted.
Wish me good luck!

Did the Bykski water block work for the KO? I'm in the same situation and would like to know if the waterblock is compatible.

This video in says the pcb is identical to the tuf. Isn't that a different waterblock?

It's done!
The block arrived on Jan 15th.
Below the steps for installing it.
I ordered the GPU block, RGB, and back-plate.

No instructions included! I had to guess what goes where, but it was not my first GPU block to install, so I managed.
The block is stunning:

First, remove the original dual-fan heatsink:

Here the PCB. This may be the first customer-made picture of it.
It looks identical to the DUAL model.

...time to look at the back side, with thermal pads there too:

Critical moment now... will it fit?

But first, some new pads and thermal paste:

IT FITS!!!
YES, YES, YES!!!

Time to install the back-plate with thermal pads too:

...at least, the right screws are provided

Done!

Time to see it altogether:

It's really a beauty!

Now, installed in the ITX side of my dual system, custom water-loop, of course:

and how it looks like in the whole system:

Red is the ITX gaming system, blue is the TR working system.
I am so glad that it worked!
