Noise is conventionally defined as an interfering signal to be eliminated in mainstream physics and engineering. Based on the universal topological axioms of the PFUSRC framework and the dual-origin system of Noetic Element and Affective Element, this paper conducts an ontological reconstruction of noise. This study demonstrates that noise is not redundant dissipation, but the intrinsic fluctuation of Noetic and Affective Element fields. It acts as the dynamic residual reverberation beyond the static order fingerprint of time crystals, sharing the same origin and field with spacetime fingerprints while maintaining complementary symbiosis with them. Moderate noise is an indispensable prerequisite for field steady states, biological rhythms, systemic self-organization and cognitive robustness. Complete silence violates the operating laws of fundamental fields, which inevitably leads to loss of systemic activity and structural rigidification. This paper establishes a universal constraint equation for noise involving a lower threshold, an optimal value and an upper threshold, and clarifies the non-monotonic topological response relationship between noise intensity and system performance. A scientific prediction is further proposed: noise with a magnitude matching the scale of the Affective Element field can improve the intellectual level and human-like reasoning capability of artificial intelligence. Noise is not universally superior when minimized; excessive denoising will break down the steady state of intelligence. As a complete counterpart to the time crystal theory (PFUSRC-39), this work realizes a cognitive upgrade of noise from a disruptive interference term to a fundamental substrate sustaining systemic activity.
