I don’t think you need any special software for the cooler, CAM just handles the RGB and I think the display on the block. If you can live without that (OpenRGB can potentially handle the RGB, not sure about the display) then you should be able to get rid of it (assuming NZXT let you uninstall it without needing a reinstall, unlike Asus and Armory Crate…).
