Here we make an attempt to extend the idea of generalized Hawking temperature and modified Bekenstein entropy at event horizon in fractal universe. The modified Hawking temperature and Bekenstein entropy is considered in the governing Friedmann equations, which is modified in the background of a fractal universe. The validity of the Generalised second law of thermodynamics (GSLT) and Thermodynamic Equilibrium (TE) have been examined in a fractal universe filled with perfect fluid having constant equation of state in four different generalized Bekenstein system. Finally both laws are examined and compared numerically in all four cases.
