Our BlueAM4 cooler has a more secure screw-mounted design unlike most motherboard’s clip-on mount setup that are notoriously harder to install and unreliable. In order to correctly install our fan, the stock plastic clip-on retention brackets (on each side of the processor socket) need to be removed first – simply use a screw driver to unmount them. Then you can install the BlueAM4 cooler securely simply by screwing down all 4 built in mounting screws.
