In this paper, we prove that the maximum norm of the deformation tensor of velocity gradients controls the possible breakdown of smooth (strong) solutions for the three dimensional (3D) compressible non-isentropic magnetohydrodynamic (MHD) equations with zero heat-conductivity. Therefore, if the maximum norm of the deformation tensor of velocity gradients remains bounded, it is not possible for other kinds of singularities. Our results are same as Beale-Kato-Majda type criterion for compressible viscous barotropic flows (Huang et al., 2011 [17]), and do not depend on further sophistication of the non-isentropic MHD model, it is independent of the pressure and magnetic field. Furthermore, this extends the corresponding Zhong's results (Zhong, 2019 [46]), and removes the viscous coefficients restriction condition 3 μ> λ and the boundedness of pressure. As a byproduct, the same results also hold for compressible non-isentropic Navier-Stokes equations without heat-conductivity.
