LENOVO ThinkSystem ST650 V2/V3 Performance Fan Kit (Part Number: 4M27A60832) is a high-performance dual-rotor hot-swap fan module engineered specifically for Lenovo ThinkSystem ST650 V2 and ST650 V3 servers. This fan kit features a counter-rotating dual-rotor design that delivers significantly increased airflow compared to the standard single-rotor fans, ensuring optimized cooling efficiency under demanding server workloads.

The performance fan provides N+1 rotor redundancy, meaning if one rotor fails, the system continues to operate without performance loss at ambient temperatures 27°C or below, enhancing server reliability and uptime. Please note fan types—performance dual-rotor and standard single-rotor—cannot be mixed within the same system to maintain optimal cooling balance.

Designed for hot-swap capability, this fan kit simplifies serviceability and ensures minimal operational disruption. Installation and configuration are supported by Lenovo’s comprehensive documentation, including hardware installation instructions and firmware updates. Ideal for data centers and enterprise environments requiring robust cooling solutions for Lenovo ThinkSystem ST650 servers.
