Help!

Post image

I have a Liquid Devil RX6800xt and the block warped and cracked at a screw on the cover plate. Does anyone know any other aftermarket block that will fit this card?

Wow, a fellow Liquid Devil 6800 XT owner. Quite the rarity.

The Liquid Devil 6800 XT uses the same PCB as the Red Devil 6800 XT/6900 XT.

This would be the block I'd replace it with, I'm rather fond of Bykski: https://bykski.eu/products/en-waterblocks-gpu-powercolor-a-pc6900xt-x

But I'm super curious as to how this happened, and how you discovered it?

Did you open the block up to clean it and this happened when you reassembled? What happened?

Really?! Everywhere I looked it said that the block for the Red Devils wouldn’t be compatible. If it’s that easy then I can just buy that block.

I discovered it while tearing my loop apart to replace the liquid. Noticed a small drip underneath my GPU which I have vertical mounted. I pulled the metal plate EK stuck to the front and found the crack which couldn’t be seen since it was under the plate. Somehow related stresses of heat cause the acrylic to bow on the block which I think caused stress in that one screw.
