The CRESST experiment observes an unexplained excess of events at low energies. In the
current CRESST-III data-taking campaign we are operating detector modules with different
designs to narrow down the possible explanations. In this work, we show first observations
of the ongoing measurement, focusing on the comparison of time, energy and temperature
dependence of the excess in several detectors. These exclude dark matter, radioactive
backgrounds and intrinsic sources related to the crystal bulk as a major contribution.
