We investigate a heat flow instability arising due to transverse perturbation of an initially uniform flow. Its growth rate is shown to be determined by the magnitude of the heat flux. The presence of ion acoustic turbulence driven by the flux itself leads to stabilization of the instability due to a decrease of the transverse heat flow.
