Fluctuations of the color superconducting gap in hot and dense quark matter are investigated in terms of the phenomenological Ginzburg-Landau approach. Our estimates show that fluctuations of the di-quark gap may strongly affect some of thermodynamic quantities even far below and above the critical temperature. If the critical temperature of the di-quark phase transition were rather high one could expect a manifestation of fluctuations of the di-quark gap in the course of heavy ion collisions.
