Observations point toward weak levels of turbulence in protoplanetary disks, and theoretical studies now focus on magneto-thermal winds rather than MRI turbulence as the main driver of mass accretion. Although MHD turbulence might be quenched, laminar magnetic structures may still transport angular momentum and induce substantial accretion heating inside the disk. Using steady-state radiative MHD models, I will show how magnetic fields can impact the thermal structure of the inner disk despite extremely low ionization fractions.
