1. Overview

Fan cords are specialized power cables designed to connect cooling fans to power sources in electronic and mechanical systems. They play a critical role in thermal management by enabling efficient heat dissipation in devices ranging from consumer electronics to industrial machinery. Modern high-performance systems require precise thermal control to maintain operational stability, prevent overheating, and extend component lifespan.
