Lenovo 4XF7A82410 ST650 V2V3 GPU AIR Duct KIT

Lenovo 4XF7A82410 ST650 V2/V3 GPU Air Duct Kit

Overview

The Lenovo 4XF7A82410 is a GPU air duct kit designed for the ThinkSystem ST650 V2 and ST650 V3 tower servers. When you add a discrete GPU to one of these platforms, the standard chassis airflow path may not adequately channel cooling air across the GPU heatsink — this duct closes that gap, directing airflow precisely where the card needs it and preventing thermal throttling under sustained compute or inference workloads. This is a factory-new, genuine Lenovo server option, not a workaround or aftermarket part.

Compatibility

Designed specifically for the Lenovo ThinkSystem ST650 V2 and ST650 V3 tower servers. If you are configuring or upgrading either of these rack and tower servers with a GPU option, verify your GPU and server generation against Lenovo's options compatibility matrix before ordering — not all GPU cards in the ST650 V2/V3 lineup require the same duct configuration. This kit is not compatible with ST650 V1, ST558, or other ThinkSystem tower generations. If you are sourcing server accessories and upgrade kits for a mixed fleet, confirm the exact chassis revision before committing.

Installation Notes

Installation is performed inside the ST650 V2/V3 chassis with the server powered down and disconnected. The duct mounts in the GPU bay area to create a sealed airflow channel between the chassis fan array and the GPU cooler. No additional tools beyond standard server hand tools are required, but the chassis cover must be fully removed for access. Do not operate the server with the duct partially seated — an unsealed duct can redirect airflow away from the GPU rather than toward it, worsening thermals. Refer to the server hardware installation guide for your specific ST650 generation for torque and seating confirmation steps.
