We evaluate the one-loop correction to the spectrum of Kaluza-Klein system for the Φ3 model on R1,d × (Tθ2)L, where 1 + d dimensions are the ordinary flat Minkowski spacetimes and the extra dimensions are the L two-dimensional noncommutative tori with noncommutativity θ. The correction to the Kaluza-Klein mass spectrum is then used to compute the Casimir energy. The results show that when L > 2 the Casimir energy due to the noncommutativity could give repulsive force to stabilize the extra noncommutative tori in the cases of d = 4n - 2, with n a positive integral.
