Click that first link, and tell me what it says above your address bar at the top
Non-reference card, so those blocks will not fit, you are looking at universal blocks and ramsinks there mate, no bad thing as you can use those on your upgraded card in the future as well
The link you posted I referred to, in non-hyperlink format.
Says non-ref to my eyes, but the cooling configurator you posted has a list of what will fit and any restrictions therein like plate adaptors etc
but as I may have mentioned to you before, avoid EK Nickel,
