Lenovo 4H47B03709 ThinkSystem Fan Module Option Kit Server Accessory
Overview
The Lenovo 4H47B03709 is a Performance Fan Module Option Kit specifically engineered for the ThinkSystem SR650 V4 and SR650a V4 rack servers. This high-static-pressure fan is a critical component for servers configured with high-TDP (Thermal Design Power) processors, dense NVMe storage arrays, or high-performance GPU accelerators. By delivering increased airflow and superior thermal dissipation, this performance fan ensures that the server’s most heat-intensive components maintain optimal operating temperatures, preventing thermal throttling and extending the lifespan of the hardware.
The kit is designed for high-availability environments, supporting the ThinkSystem’s hot-swap architecture. This allows IT administrators to replace or upgrade fan modules without powering down the server, ensuring continuous uptime for mission-critical applications. The “Performance” designation indicates a higher RPM and CFM (Cubic Feet per Minute) rating compared to standard fan modules, making it a mandatory requirement for specific high-performance internal configurations as defined by Lenovo’s technical thermal guidelines.
As a genuine Lenovo ThinkSystem accessory, the 4H47B03709 is fully integrated with the server’s XClarity Controller (XCC). This integration allows for precise, automated fan speed adjustments based on real-time sensor data, balancing cooling efficiency with power consumption. Each module is built to rigorous enterprise standards, featuring dual-ball bearing designs for 24/7 reliability in demanding data center environments.
