Question Waterblock for a Sapphire Radeon RX 6800 XT Pulse ?

[rigger922]

Greetings,

I'm looking at potentially putting a custom loop in my system, However it seems that may be harder than I thought. I cannot seem to get a straight answer from anywhere regarding a water block for the Sapphire Radeon RX 6800 XT Pulse.

The only thing I can find is this:
https://www.bykski.us/products/byks...or-sapphire-rx-6800-super-platinum-a-sp6800-x.

And I'm not sure about buying from this website as it seems a bit dubious since barely anything on there has a review. Does anybody here have any suggestions for me?

I have looked at AIO's for the GPU since I'm already running a 420mm Arctic AIO on my CPU, but that seems to be the same.

The problem with mid-range cards is they often don't get waterblocks designed for them. Those willing to watercool for the $300-400 that costs for a loop generally don't buy mid-range cards.

There are few RX6800 blocks out there, but only because the OEMs used the same PCB layout or RX6800/RX6900 cards. So your high end Gigabyte Aorus Master, ASUS Strix, etc.


In terms of quality, I purchased a Bykski 3080/3090 EVGA FTW3 block once. It wasn't great, I couldn't get sufficient mounting pressure and temperatures weren't much better than air cooling. Could have been a one off, but I purchased an EK instead and that has worked much better. It will at least work, and you may have fiddle with thermal pad thickness (still pretty sure that was my main issue, the block fit, just wouldn't squish down with the included pads it seemed to me)

Near as I can tell the Super Platinum block looks like it should fit the Pulse and Nitro PCB pretty easily. Same VRM and Memory layout near as I can tell.

Way more pictures of the Pulse board for some reason, but everything seems to line up.

If your PCB looks like that, I think you are okay to buy.

Here is someone on Reddit saying they have the Bykski block on the same card from 3 years ago

It looks like they make them to order so they aren't sitting on stock....... unlike EK I did check EK's webpage and they stop at the 6850 for blocks, but im not sure if your card shares the same layout as other cards

Some cheaper options. These also only list the Nitro, but as near as I can tell, that is the same PCB on the Pulse. Especially after what faalin tracked down.
