NOT COMPATIBLE WITH AM4 in Cooling Posted May 14, 2018 As you can see the backplate that comes with the 240 doesnt fit. I know I'm using the backplate in the pictures but after many removals and insertion again and again of the stock cooler to try the new one. I'm not taking it back off again until I'm given a solution . I have tried with the backplate off and it doesn't fit even if I get aggressive and try to. I end up scraping parts of my motherboard every time at the holes. Also as you can see when I use the backplate as an example, only the replacement bracket I ordered (as recommended) fits. However that bracket does not fit on the 240 as you can see its not wide enough and the gap is too deep for it to sit on the 240.
