We propose XMM-Newton observations of two middle-aged radio-quiet Fermi pulsars J0554+3107 and J0622+3749. The former is associated with the supernova remnant G179.0+2.6 which provides a great advantage for confident constraining its distance and evolution stage. Using Chandra comma eROSITA and Swift shallow exposures we have found their X-ray counterparts. Thermal spectral components dominate their X-ray emission. Measurements of the parameters of these components are important for comparison with neutron star cooling theories and the study of fundamental properties of superdense nuclear matter inside the stars. However comma any accurate conclusions are impossible due to low count statistics. We request for followup observations to study thermal emission from these pulsars.
