In creation of cold dark matter (CCDM), accelerated expansion of Universe can be achieved by negative creation pressure. Entropy is a basic concept in thermodynamics which is used to analyze different models in the framework of CCDM. In this work, we investigate the thermodynamical behavior of fractal Universe and DGP brane world model with the help of different matter creation models 
through thermodynamic relations, i.e., 
(generalized second law of thermodynamics) and 
(thermal equilibrium condition), where S is the total entropy, and z is a redshift parameter. It is found that fractal and DGP brane world models provide satisfactory results for generalized second law of thermodynamics and thermodynamic equilibrium.
