The universality of the Critical Temperature included Fluctuation Model(CTFM) in explaining the evolution of the giant dipole resonance (GDR) width asa function of angular momentum is examined in the light of recent experimentaldata on $^{144}$Sm and $^{152}$Gd. We compare both the data sets with thephenomenological formula based on the CTFM and the thermal shape fluctuationmodel (pTSFM). The CTFM describes both the data sets reasonably well using theactual ground state GDR width ($\Gamma_0$) values, whereas, the pTSFM describesthe $^{144}$Sm data well but is unable to explain the $^{152}$Gd data using asingle value of $\Gamma_0$ for two excitation energies. These interestingresults clearly indicate that the phenomenological CTFM can be used universallyto describe the evolution of the GDR width with both angular momentum andtemperature in the entire mass region. Moreover, it should provide new insightsinto the modification of the TSFM.
