That is not how you do ot on this cpu cooler ,here is the link to the one I have http://www.corsair.com/en-us/hydro-series-h100i-extreme-performance-liquid-cpu-cooler
Oh yours has the newer mounting style vs the old round style. IIRC i think that one does come with an AM4 bracket.
Oh wait, that's the top mounting one. Well in that case, I'm not sure. The page says that it's AM4 compatible out of the box but that coudln't have been the case when you bought that.
