Lenovo 4H47A96819 SR630 V4 Standard Hot-Swap Heatsink

Overview

The Lenovo 4H47A96819 is a standard heatsink designed for the ThinkSystem SR630 V4 rack server platform. It provides the thermal dissipation required for standard processor configurations — the right fit when deploying an SR630 V4 with base TDP CPUs and you need a replacement or additional heatsink without upgrading to a high-performance cooling tier. At 10 lb, this is a substantial precision-machined component; handle with care during installation to avoid fin damage that would compromise airflow.

Compatibility

Designed specifically for the Lenovo ThinkSystem SR630 V4 rack servers. This heatsink is matched to standard (non-performance) processor TDP ranges on the SR630 V4 platform. Verify your CPU's thermal design power against Lenovo's SR630 V4 configuration guide before ordering — high-TDP processors require the performance heatsink variant, not this unit. Do not attempt cross-installation with SR630 V3 or other ThinkSystem generations, as heatsink mounting interfaces differ between platform generations.

Installation Notes

Installation follows standard SR630 V4 processor installation procedure. Ensure the system is powered down and all ESD precautions are observed before handling. Apply thermal interface material per Lenovo's service documentation if the processor is being reseated — the heatsink does not ship with pre-applied TIM noted in available evidence. Confirm torque specifications from the SR630 V4 Hardware Maintenance Manual for the retention screws to avoid warping the load plate or cracking the heatsink base. Manufactured in Mexico (Country of Origin: MX).
