The first one seems like reference design so its surprising if there is some block that is not fitting on it. Second one, however, might be similar to the FleX and VaporX designs if it has the additional metal heatspreader under that two fan cooler.
Btw, any core only block (including, for example, the heat killer I have) with sufficient mounting hole distance should fit on both of these cards with heatspreader off - my reason for getting a smaller block was just that I wanted to keep the heat spreader. I could have removed it, put passive heatsinks on vRAM's and VRM's and use the blocks I have. Ot just take the heatspreader off and cut it about 3 mm shorter near the GPU core - but that would be far too obvious break of warranty. Sapphire ofc voids your warranty the second the stock cooler comes off, but as long as you keep the stock cooler and put it back on if you need to go through warranty they would have hard time proving your card is out of warranty
Given option I would prefer companies with more reasonable warranty terms, like, for example, Club 3D.
