Lenovo 4M27A60831 ST650 V2 Standard FAN KIT

Lenovo 4M27A60831 ST650 V2 Standard Fan Kit

Overview

The Lenovo 4M27A60831 is a standard fan kit designed as a direct replacement or supplemental cooling component for the ThinkSystem ST650 V2 tower server. At 10 lb, this is a substantial assembly — not a single rotor, but a full fan module kit sized for the ST650 V2 chassis airflow path. Deploying this part restores factory thermal management when a fan module fails or is flagged during predictive maintenance, avoiding unplanned downtime on a production server. If you're expanding the ST650 V2 configuration toward higher CPU or memory loads, confirming proper fan population per Lenovo's thermal guidelines may require this kit to meet cooling requirements for the populated slot count.

Compatibility

The 4M27A60831 is specifically designed for the Lenovo ThinkSystem ST650 V2 tower server. Verify chassis generation before ordering — ST650 V2 fan modules are not interchangeable with ST650 V1 or other ST-series towers (ST550, ST558, ST250). Cross-reference your server's machine type and model (MTM) against Lenovo's parts compatibility list to confirm this fan kit matches your exact build configuration before installation. This part falls under UNSPSC code 43211600 (computer servers and server components), consistent with server internal hardware.

Installation Notes

Fan kit replacement on the ST650 V2 is a hot-swap-capable operation on supported configurations — consult your server's maintenance manual to confirm whether your specific build permits hot-swap before proceeding without a maintenance window. Ensure the chassis is properly grounded before handling. Follow Lenovo's documented fan installation sequence for the ST650 V2 to maintain balanced airflow across all bays; incomplete fan population can trigger thermal alerts or throttle CPU performance. No specialty tools are required for standard fan bay replacement, but an ESD wrist strap is recommended when working inside the chassis.
