About this part
The Bykski A-GV9070GMOC-X is a full-coverage GPU water block with a matching aluminum backplate. Its copper base covers the GPU chip, the memory and the power stages, and the transparent top shows the coolant loop.
Cooling the memory and power stages directly, not only the GPU chip, lowers card temperatures under load and removes the stock cooler's fan noise from the build. It is the choice for a custom loop over an AIO.

Sealed kit, or just the block

As the card ships
|
|
|---|---|---|---|
| You already have | A case with a 360 mm radiator mount. Nothing else. | A working water-cooling loop: pump, radiator, reservoir, fittings, coolant. | The card and the air cooler it came with: a heatsink and fans that blow the card's heat into the case. |
| Day one | Remove the stock cooler, install the pads and the block, mount the radiator. Done. | Same block install, then plumb it into your loop, fill and bleed. | Nothing to install. Under a long gaming or render load the fans spin up and the heat stays in the case. |
| Serviceable | Sealed. Nothing to fill, bleed or top up. | Every part, because it is your loop. | Clean the dust out of the fins now and then. The cooler can only work with the air your case gives it. |
| Best for | Gaming and creator builds that want the card cool and quiet, with no loop to build. | A build that already has water in it. | Short loads in a case with plenty of airflow. |

Customer Reviews
thumbs up
Great product. Super easy to install. My 2nd waterblock after a 1080 back in the day. All pads and thermal compound included. Great temps produced.
Only needs some printed instructions in the box.
I've used Bykski full coverage blocks before, and this once isn't any different. Ease of install, straightforward and a flush fit. My only concern would be determining appropriate o-ring sizes for my blocks in case I would need to replace them after cleaning out fins every now and then, and they're not advertised with the product.
works great I have two of them.
