70W Copper Passive Cooling CPU Radiator for Server 5G Optical Module Cooling

70W Copper Passive Cooling CPU Radiator designed for high-performance server and 5G optical module cooling applications.

The standard 1U heat sink measures 4.445cm in thickness, conforming to EIA industry standards recognized worldwide. As the foundational generation of server heat sinks, this product category continues to expand its applications across the computerized industry. With the growing prevalence of digital equipment, 1U server heat sinks have become essential components in server cooling systems, designed to fit standard assembly spaces while delivering exceptional cooling performance.

The 1.5U heat sink was developed for specialized server architectures. While initially limited in cooling capacity, it provided valuable technical insights that paved the way for advanced server heat sink innovations, establishing the foundation for 1.5U, 2U, and 3U server cooling solutions.
