Bykski Full Coverage GPU Water Block and Backplate for Asrock RX6900 XT OC Formula 16G (A-AR6900XTOCF-X)
This full coverage block directly cools the video cards core (GPU), graphics memory (RAM), and voltage regulator modules (VRM). By directly cooling these components you can achieve great temperatures along with the ability to reach higher overclocks or extend the overall lifespan of your card by running at below factory temps.

Warnings
This is a repair or replace only item. Returns not accepted on compatibility issues or if block has had water/fluid run through it.
Manufacturer reserves right to alter block design to expand compatibility. Delivered item may not 100% match pictured item. Product does NOT come with English instructions. Please see product gallery images for install guide if available. Generally, thermal pads should be installed on the card where the block has corresponding raised contact points with the exception of the GPU core, which uses thermal paste. Installing pads on other components can lead to improper contact and poor performance.
Not responsible for any damage caused by or when using this product. Please use at your own risk.
Customer Reviews
This was the most nerve wracking part of my first custom water cooling rig since there are so many video card makers. I have the Asrock RX6950 XT OC Formula card and had to confirm that this product would fit. Customer support was able to answer my question. The only thing I'd like to see improved is the documentation. The documentation was really fine print and I end up looking up my disassembly on YouTube and previous reviewers for tips to install properly.
Installation aside, the working system is pretty. I have it hooked into my MB ARGB sync.
Took awhile to receive water block but customer service was top notch about keeping me in the loop. As for the water block itself performs excellent. Keeps my AsRock 6950 OCF at 50c core 72c hotspot overclocked @ 2920mhz core, 2400mhx memory @ 1.225v and 20% power boost with MPT. Great product!
The block is fantastic, there was a little bit of oil residue inside the block that I had to clean out before installing it, though anyone doing a custom loop should flush their equipment first. The thermal pads didn't have much explanation but I can give a good breakdown here:
You can not use ANY of the stock thermal pads on the front of the PCB, you MUST use the ones included with the block and only put them in the exact locations as the directions state. Nowhere else. However, you can reuse the stock thermal pads on the back of the PCB for additional memory/VRM cooling. They fit nearly perfectly and there is no PCB flexing or bending when you use the stock thermal pads underneath the backplate.
Just to reiterate, you need to use the thermal pads that are included with the block on the front side of the PCB, but you can use the stock thermal pads that are included with the GPU on the back side of the PCB.
Other than some minor confusion with the thermal pads, everything else is perfect, the fit is great and the mounting pressure is very even. Keeps my ASRock 6950XT OC Formula nice and chilly. Able to sustain 2.75GHz on the core and 2.35GHz on the memory. GPU average temp typically sits around 42c and hotspot around 56c under full load at +20% power target & 1.2v Vcore. Smokes the 3090 in most games and typically matches the 3090Ti in non-raytraced games. Very, very happy!
Water block is great. Cools well and fits perfect however, thermal pads that were provided were not the correct thickness and additional pads were needed for proper contact between gpu and cooler.
