The Supermicro FAN-0113L4 is a high-performance 40x28mm axial cooling fan engineered specifically for 1U rackmount chassis environments where thermal density is a critical concern. Designed for seamless integration into Supermicro’s SC813, SC815, and SC113 series chassis, this fan provides the necessary static pressure to drive consistent airflow through tightly packed components, including high-TDP processors and dense NVMe storage arrays.
