A detailed experimental study of the steady-state temperature in a 3D optical lattice for cesium has been performed for a wide range of detunings. Specifically, we have investigated the situation with the cooling and trapping light detuned far red of a ()-transition, where the blue detuned interaction with a ()-transition can not be neglected. We find that the temperature scales with the optical potential due to the interaction with just the ()-transition. This indicates that blue Sisyphus cooling has essentially no effect on the dynamics of the system, when there exists a neighbouring red detuned transition.
