I recently received an AM4 bracket (part number RR-AM4B-H212-S1) and installed it according to the included directions and the posted YouTube video. Unfortunately, the heatsink is not being held tight against the processor as one should expect. The included standoffs that screw into the stock backplate do not keep it taut against the motherboard. I would say there is 1/16"-1/8" of play. This is on an ASUS PRIME X370-PRO motherboard. Also, The Hyper 212 Plus can be made to rotate on top of the processor, several degrees in either direction, with very little exertion force. Have I missed something critical in the instructions? I've tried to start a ticket about this, but it won't go through no matter what I try. I am getting very frustrated.
