Lenovo 4M27A11843 ST650 V2 T4 GPU Thermal KIT

Lenovo 4M27A11843 ST650 V2 T4 GPU Thermal Kit

Overview

The Lenovo 4M27A11843 is a purpose-built thermal kit designed to support T4 GPU installation in the ThinkSystem ST650 V2 tower server. When adding an NVIDIA T4 GPU to the ST650 V2, the server's thermal architecture requires supplemental hardware to maintain safe operating temperatures under sustained GPU compute load — this kit provides the mechanical and thermal components Lenovo specifies for that configuration. Sourcing 4M27A11843 as a genuine factory component ensures the installation meets Lenovo's thermal validation standards rather than relying on improvised solutions that could compromise cooling margins or void service agreements.

Compatibility

Designed exclusively for the Lenovo ThinkSystem ST650 V2 tower server paired with an NVIDIA T4 GPU. This kit is specific to that server-GPU combination — it is not a universal thermal accessory and should not be applied to other ST650 generations or GPU models without confirming Lenovo's compatibility matrix. If you are deploying GPU compute in a rack or tower server environment and are unsure which thermal option applies to your specific ST650 V2 configuration, verify against the Lenovo ST650 V2 product guide before ordering.
