ARCTIC Kühler Freezer 4U-M CPU Cooler for AMD socket SP3 content_copy

The ARCTIC Freezer 4U-M Rev. 2 is a high-performance 4U server cooler, specifically designed for use in server and workstation environments with high demands for reliability, efficiency, and longevity. It is compatible with processors from AMD and Intel, including modern sockets such as LGA 4189, LGA 4677 (Socket E), LGA 4710 (Socket E2), SP6, Socket TR4, TR5, sTRX4, and socket sWRX8. With a Thermal Design Power (TDP) of 350 W, it ensures effective heat dissipation under heavy loads, making it ideal for powerful server systems. The cooling unit features 8 heat pipes with a diameter of 6 mm and an aluminum fin heatsink with 57 fins, enabling optimal heat distribution and dissipation. Two 12-cm fans with dual ball bearings ensure stable, quiet operation and a long lifespan—the maximum noise level is only 40 dB, while the airflow of 122.16 m³/h (equivalent to 71.9 cfm) provides efficient cooling. The fans are controlled via a 4-pin connector, allowing for precise speed regulation. The compact design, with a height of 145 mm and a width of 156 mm, fits perfectly into standard 4U rack systems. The cooler is made of aluminum and black and offers a robust, durable construction for continuous operation in professional IT environments.
