In this paper, the process of formation of high-temperature entangled states in a system of two coupled quantum parametric oscillators with a partially coherent pumping is considered. It is shown that the presence of noise in the pump has a significant impact on the dynamics of the system. It imposes a limit on the temperature at which the entangled states are formed, determines the lifetime of entanglement in the system
