  We explore extensive N-body simulations with two-component cold dark matter
candidates. We delve into the temperature evolution, power spectrum, density
perturbation, and maximum circular velocity functions. We find that the
substantial mass difference between the two candidates and the annihilation of
the heavier components to the lighter ones effectively endow the latter with
warm dark matter-like behavior, taking advantage of all distinct features that
warm dark matter candidates offer, without observational bounds on the warm
dark matter mass. Moreover, we demonstrate that the two-component dark matter
model aligns well with observational data, providing valuable insights into
where and how to search for the elusive dark matter candidates in terrestrial
experiments.
