Present study meticulously analyzes the Shannon entropy-based magnetocaloric effect (MCE) of GaAs quantum dot (QD) containing Gaussian impurity and in presence of Gaussian white noise (GWHN). Two diverse paths for the application of GWHN viz. additive and multiplicative are assumed. The inspection unfurls highly subtle and complex interplay between temperature, GWHN, the noise mode and the nature of the physical quantities involved that eventually shapes the MCE profiles. Under some typical conditions the MCE maximizes which merits important technological relevance. The physical traits of the MCE profiles manifest greater departure from the noise-free state under multiplicative noise than its additive relative. In most cases, additive and multiplicative noise diminishes and enhances the MCE, respectively, with respect to the noise-free ambience.
