Lenovo 4XH7B08937 SR860 V4 Full Length GPU Thermal KIT

Lenovo 4XH7B08937 SR860 V4 Full Length GPU Thermal Kit

Overview

The Lenovo 4XH7B08937 is a full-length GPU thermal kit designed for the ThinkSystem SR860 V4 rack server. Installing a full-length GPU in a high-density 4-socket server without the correct thermal hardware is a configuration error — this kit provides the mechanical and thermal components required to properly seat and cool a full-length GPU card in the SR860 V4 chassis, keeping the system within thermal spec under sustained compute workloads. At 10 lb, this is a substantial assembly, not a lightweight bracket — expect dedicated heatsink or airflow duct components rather than simple sheet-metal hardware.

Compatibility

Designed specifically for the Lenovo ThinkSystem SR860 V4 server platform. The SR860 V4 is a 4-socket, 4U rack server; this kit addresses the full-length GPU form factor slot configuration in that chassis. It is not interchangeable with SR860 V2 or V3 thermal kits — chassis airflow paths and GPU retention geometry differ across generations. Verify your SR860 V4 build configuration against Lenovo's system configuration guide before ordering; GPU slot assignment (and therefore which thermal kit applies) depends on your processor and PCIe riser configuration. If you are sourcing server components for an SR860 V4 GPU deployment, confirm the GPU is full-length before specifying this kit — half-length and low-profile GPUs use separate thermal assemblies.

Installation Notes

Installation requires following the SR860 V4 hardware maintenance manual sequence — GPU thermal kits in 4-socket platforms involve airflow baffles that must be seated before the GPU card is installed, not after. Incorrect baffle placement blocks chassis fan zones and can cause CPU or GPU throttling under load. Country of origin is Mexico (MX); UNSPSC code 43211600 (computer server hardware components). This is a factory-new, genuine Lenovo part sourced through distribution — no grey-market, no parallel imports.
