How does EKWB make their backplates exclusive to their waterblocks?

I was looking into buying a backplate for my GTX 970(reference PCB) I was looking at 3 different ones EVGA's which only works on EVGA cards, Heatkillers which doesnt help with cooling at all and EKWB which says it only works if you have an EKWB water block. how did they make it incompatible? I am looking at my GTX 970 and it has the screws in the same place the FCGTX 970 backplate does, so couldnt I just take them out put the backplate on and put the screws back in? I am very confused....

The backplate uses the same PCB holes that exist on the stock cooler and for reference PCB water blocks. Now, since I have an EK block and backplate, what you are speaking of is that the EK backplate actually screws into the EK waterblock on the front. You actually leave several screws out of the waterblock install steps that would normally be used to secure the PCB to the block, but instead, install the backplate, then use longer screws to secure all together, like a sandwich. EK backplate and another vendor waterblock likely aren't going to be compatible due to the waterblock not having these mounting points to use a backplate.

Hope this helps clarify.

they did not, but it sounds good and prevents most people from trying to interchange them, and I cant think of any back plate that would help with cooling?

with that stated that does not mean that a stock 980 back plate will fit on a 980Ti card or even a Asus 980 gold card if the screw hole lay out has changed on the cards PCB than they are not compatible.

the back plate is designed to prevent the card from sagging under the weight of the block so that the PCB board that the card is made from does not get damaged.
