Just heard back from NZXT, apparently the Kraken is supposed to stay in whatever mode you last set it to even if you uninstall CAM. But I can't actually see anyway of testing this, because after setting it to Performance mode and uninstalling CAM I have no way of seeing what mode it's in anymore, and it doesn't report its rpm to the motherboard via its 2pin connector. And whenever I reinstall CAM it just shows everything back in Silent mode.
