We investigate the thermal conductivity of classical spin chains through a Green-Kubo approach using both Monte Carlo and Langevin simulations as well as by direct numerical determination of the microscopic heat transfer processes. All three approaches show that magnetic heat conductivity is normal for all finite temperatures and magnetic fields. In ferromagnets, heat conduction grows linearly with the magnetic field while in antiferromagnets this holds only at high fields. At low fields a quadratic decrease leading to a minimum is attributed to spin mode velocity suppression.
