Lenovo 4F17A80568 ST50 V2 System Rear FAN KIT

Lenovo 4F17A80568 ST50 V2 System Rear Fan Kit

Overview

The Lenovo 4F17A80568 is a factory-new rear fan kit designed as a direct replacement for the ST50 V2 tower server. When a chassis fan fails or degrades — causing thermal throttling, noisy operation, or sustained high-temperature alerts — swapping in 4F17A80568 restores proper airflow through the system, protecting CPUs, storage drives, and memory from heat-related failures. This is a purpose-built Lenovo component, not a generic aftermarket substitute, which means it fits the mounting points, connector headers, and firmware fan-speed monitoring of the ST50 V2 without modification.

Compatibility

This fan kit is designed for the Lenovo ThinkSystem ST50 V2 tower server. Confirm your system model before ordering — the ST50 V2 has a distinct chassis from the original ST50, and fan assemblies are not interchangeable between generations. If you are sourcing replacement cooling components for other server platforms in your environment, verify the part number against your specific system's hardware maintenance manual, as Lenovo fan kits are chassis-matched.

Installation Notes

At 1.00 lb and 10.70 x 7.30 x 4.60 in, the fan kit ships in a package sized for safe transport of the full assembly. Installation is a tool-assisted swap inside the ST50 V2 chassis — power down and disconnect the server from AC before removing the existing fan assembly. Reconnect the fan cable to the system board header and confirm firmware recognition via the server's onboard management interface after reassembly. No additional hardware or adapters are required for a like-for-like replacement.
