The width of the giant dipole resonance (GDR) at finite temperature T in 120 Sn is calculated within the phonon damping model including the neutron thermal pairing gap determined from the modified BCS theory. It is shown that the effect of thermal pairing causes a smaller GDR width at T&2 MeV as compared to the one obtained by neglecting pairing. This improves significantly the agreement between theory and experiment, including the most recent data point at T=1 MeV.
