No problem man, I think I get what you're saying. The stock backplate (kind of a murky unpolished clear look right?) that sits behind the motherboard should have 4 screws going into it. 2 from the top back clip and 2 from the bottom back clip. Those 2 black back clips have to stay on to mount the cooler to them. There shouldn't be any screws that go into them from the pump mounting plate. The 2 mounting screws (1 each for for the two separate slide in pieces that slide into the pump block) that hold the pump cooler in place should have one of those little square clips with the handle inserted into each one so it kind of hangs from them. It's hard to freeze frame it but between 8:53 and 9:00 in the video you can kind of see the screws dangling off each of the two clips. Those little square clips should "clip" over the middle of the backplate brackets (freeze a 8:31 of the video and you can see the tab sticking out in the middle of the two screws) maybe try clipping the top square piece over the top middle black tab and then clip the bottom tab over the bottom middle tab and then as long as you can kind of hold the pump cooler in place, steadily tighten the 2 screws down each little by little and it should snug up holding the pump in place. I would think with no side brackets attached it might wiggle ever so slightly but it should snug up at some point and hold pretty tight. If you're already doing all this and it's still not working then disregard lol. Just trying to make sure we're on the same page as far as parts/pieces and what's being said while having that video as sort of a baseline.
