Waterblock for XFX MERC 319 RX 6900 XT Black

[sthzje]

Hi everyone. I'm thinking of doing a full custom watercooling loop, including my GPU, but there's a catch. I'm a proud owner of a XFX MERC 319 RX 6900 XT Black Gaming GPU, but not many companies make full cover waterblocks for these cards. But I found that Alphacool makes one. The problem is, these cards come in 2 different PCB designes (V1 and V2). Alphacool has a picture on their site, where you can reference the PCB if the waterblock will fit. But I don't want to dissasemble my GPU just to find out, that the block is not compatible and voiding my warranty. Is there any other way I can confirm that the block will fit my GPU?

You'll need to disassemble your GPU to put the block on anyway. Why not do it now and find out? 
Also, disassembling a GPU doesn't actually void warranty, though XFX says it does

Well, because for now I'm just thinking of it, and I'm in the process of gathering information. But now that you said that, I went through XFX's warranty information and apparently, disassambling the GPU won't void the warranty, if there isn't any physical damage made during disassembly. Well, guess I will just have to do it.
