I get the impression that you would want the surrounding fan structure. Not having a frame to prevent air from escaping around the fan blades will likely result in air moving back in the opposite direction through those areas and cycling back into it. There's a reason nearly all case fans block that off. These fans instead block off an area in the direct path of the blades. This looks like a case of form over function to me. And why would anyone want to manage their case fan lighting from a phone?...an all-aluminum skeleton frame that is designed to allow the double-layer blades to generate positive air pressure without obstruction from the fan structure.
