ARCTIC Freezer 4U-M, 2x120 mm CPU Cooler, Black

This cooler is specifically engineered for high-density computing environments requiring a 4U rack profile. The thermal structure integrates a robust heatsink utilizing eight 6 mm diameter heat pipes fabricated from copper for efficient thermal transfer. The unit supports CPUs with a Thermal Design Power (TDP) up to 350 W, accommodating demanding server-grade processors and multi-core configurations. The total installed height measures 145 mm, ensuring proper clearance within standard 4U chassis dimensions.

Heat dissipation is managed by two 120 mm fans operating under Pulse Width Modulation (PWM) control, regulating speed between 400 RPM and 2300 RPM based on temperature load. At maximum rotation, the fan assembly delivers 71.9 CFM of airflow and generates 3.3 mmH₂O of static pressure, resulting in a maximum noise output of 40 dB. The fans utilize a dual ball bearing system, providing operational stability and longevity suitable for continuous 24/7 server deployment.
