ARCTIC Freezer 4U-M Rev.2 Dual 120mm CPU Air Cooler

Description ARCTIC Freezer 4U-M Rev.2 Dual 120mm CPU Air Cooler ACFRE00133B The ARCTIC Freezer 4U-M Rev.2 (ACFRE00133B) is a high-performance 4U rack-mount compatible CPU air cooler engineered for demanding server and workstation environments. Designed specifically for rack chassis and space-restricted systems, it delivers powerful airflow and thermal efficiency while maintaining reliable, long-term operation. Equipped with two 120mm PWM fans in a push-pull configuration, the cooler generates strong, directed airflow through its dense aluminium fin stack. This setup significantly improves heat dissipation under sustained loads — making it ideal for multi-core CPUs running virtualization, rendering, or server workloads. Four direct-touch copper heat pipes efficiently transfer heat from the CPU to the heatsink array, while ARCTIC’s pre-applied MX-4 thermal compound ensures optimal thermal contact out of the box. The result is dependable cooling performance tailored for professional and enterprise builds. With robust construction and ARCTIC’s long-standing reliability, the Freezer 4U-M Rev.2 is purpose-built for 24/7 operation environments. Why It’s a Great Choice True 4U Rack Solution – Designed specifically for 4U server chassis, ensuring proper clearance and airflow alignment in rack environments. Dual 120mm Push-Pull Cooling – Two 120mm PWM fans dramatically improve airflow through the heatsink, providing stable cooling under sustained heavy loads. Built for 24/7 Workloads – Ideal for servers, render nodes, and professional systems where reliability and consistent thermal performance are critical. Efficient Heat Transfer – Four direct-touch copper heat pipes quickly move heat away from the CPU, maintaining stable operating temperatures. Easy Installation – Includes pre-applied MX-4 thermal compound, reducing setup time and ensuring proper contact immediately. Long-Term Reliability – Backed by ARCTIC’s industry-leading 6-year warranty, making it a dependable choice for enterprise and workstation deployments.
