The AFC0712DE is a Fujitsu 12‑volt direct‑current cooling fan rated at 2.5 amperes and featuring a four‑wire interface, specifically engineered for use in the Primergy RX300 S5 server chassis. Its 12‑V DC power requirement aligns with standard server power supplies, while the 2.5‑A current draw ensures sufficient airflow for reliable thermal management. The 4‑wire configuration provides separate connections for power, ground, tachometer output, and a dedicated control line, allowing precise monitoring and control within the server’s cooling system. Designed to meet Fujitsu’s stringent quality and reliability standards, this fan is an ideal replacement or upgrade component for maintaining optimal operating temperatures in the Primergy RX300 S5 environment.
