Founders cards are reference.
AIBs? nearly all of them will be different. I highly, highly doubt any one can even use the "reference" PCB from the FE this time because of the shape and cooler design.
AIBs will make their own PCBs, which will be non reference, and thus cast into a big black hole of "Willy make a water block for this card or not?".
And, like most of the 20 cards? it's usually not. Just like that KFA2 2070 Super I bought. No one made a block for it. At all. Not even Byski.
I don't know how much Asus paid EK to make blocks for their four different "Dual" models of exactly the same card, but due to Asus's choice of cheap analogue caps they had to literally cut a hole in the block and patch it with metal just to clear the sodding capactitors.
That is what that metal plate is for. The caps sat so high they could not fit a cold plate so they have an empty area patched by that slab of stainless.
And? that was lucky. That's a £150 block, BTW.
Like I said, nearly all AIB cards didn't even get a block. So not only do you have a nightmare finding the block, but you literally need to find the block first, then buy a card to fit it. Only, if someone like CCL f**k up and show the wrong picture of the wrong model (like happened to me) you end up with a £88 paper weight.
I wouldn't mind so much, but these 30 series cards are going to thrive under water. Only, good luck getting them there in the first sodding place.
Edit. Hang on a minute.
So Nvidia designed a stock reference card, then used it to make their Founders Editions? WTF?
They never cease to amaze me, and not in good ways.
