I think its a bad move considering that not many current cases supports a 360mm radiator. To fit within the current standard mounting, CM should've gone with a 240mm/280mm radiator, higher FPI, thick radiator, or a combination of any of these three criteria.
Furthermore, running a 360mm radiator solely for the CPU alone is wasteful unless the user adds the GPU within the loop. That anemic pump will be its Achilles heel and may not be good enough to support the added restriction from the GPU block.
