The pairing gaps, heat capacities, and level densities are calculated within the BCS-based quasiparticle approach, including the effect of thermal fluctuations on the pairing field within the pairing model plus noncollective rotation along the $z$ axis for ${}^{60}$Ni and ${}^{72}$Ge nuclei. The analysis of the numerical results obtained shows that, in addition to the pairing gap, the heat capacity can also serve as a good observable to detect the appearance of the pairing reentrance in hot rotating nuclei, whereas such a signature in the level density is rather weak.
