We present an analysis of the temperature and metallicity profiles of 12 galaxy clusters in the redshift range 0.1-0.3 selected from the Chandra archive with at least ∼20,000 net ACIS counts and kT>6 keV. We divide the sample between seven cooling-core (CC) and five non-cooling-core (NCC) clusters according to their central cooling time. We find that single power laws can properly describe both the temperature and metallicity profiles at radii larger than 0.1r₁₈₀ in both CC and NCC systems, with NCC objects showing steeper profiles outward. A significant deviation is present only in the inner 0.1r₁₈₀. We perform a comparison of our sample with the De Grandi & Molendi BeppoSAX sample of local CC and NCC clusters, finding a complete agreement in the CC cluster profile and a marginally higher value (at ∼1 σ) in the inner regions of the NCC clusters. The slope of the power law describing kT(r) within 0.1r₁₈₀ correlates strongly with the ratio between the cooling time and the age of the universe at the cluster redshift, with a slope >0 and τ_c/τ_age≲0.6 in CC systems.
